What opportunities for training and professional development has the project provided?Temple: Mentored 5 undergrads on SLF related projects including research skills, modeling, and web development. U Del.: This project has supported 1 graduate student - M.S. Cat Williams - who will finish in 2024. This project has also partly supported undergraduate research by 4 different undergraduate students during the reporting period and has leveraged additional support (from Hatch and department sources) for undergraduate research. Rutgers: PhD student Kasia Madalinska continues to conduct research on SLF feeding, monitoring and management in vineyards. USDA-ARS: One postdoc working in Leskey lab continue to lead experiments and publish findings. VA Tech: Training continues for 2 graduate (doctoral) student, one of whom graduated during the current reporting period, and 3 undergraduate research assistants. Provided student speaking opportunities in conferences. Graduate and undergraduate IPM training Penn State: Professional training of 2 undergraduates, 1 MS student, 1 PhD student, 3 post-doctoral scholars, 2 technicians. Many of these students have co-authored posters or presentations and presented findings at scientific meetings, and have also been mentored in writing publications from their projects. How have the results been disseminated to communities of interest?Face-to-face presentations in grower conferences and fruit schools. This includes greater focus in PA and NY on juice and wine grape growers in the Lake Erie growing region. This included a full day, in person, SLF preparation training for Erie growers held in North East, PA on May 1, 2024. In person and on-line presentations (over 50 in the current reporting period) have been provided by all project members. Numbered extension publications (recommendations and fact sheets) on Penn State Extension Spotted Lanternfly website (https://extension.psu.edu/spotted-lanternfly) Google Group mailing list for grape growers, tree fruit growers, and hop growers) Virginia Fruit web site (with dedicated SLF page) SLF Dashboard (https://iecolab.org/slfDashboard/index.html) has been shared with and updated in communication with state government agencies SCRI Project Website: StopSLF.org What do you plan to do during the next reporting period to accomplish the goals?For all aspects of the project, data collection will be completed as needed, and data analyzed and publications prepared and submitted. This includes the following stated projects (but also applies to all project objectives that comprise our major goals): 1.1 Revise and resubmit (as needed) manuscripts presently in review: Harner A, Rowles T, Kar S, Briggs L, Centinari M (submitted) Adult spotted lanternfly impacts grapevine carbon allocation post-infestation. American Journal of Enology and Viticulture. Complete 3-year field trial assessing impacts of spotted lanternfly feeding on grapevines. Complete 3-year field trial assessing impacts of spotted lanternfly feeding on grapevines. Complete host suitability testing of SLF nymphs and adults on hops. 1.3 Conduct vineyard-based test of efficacy of multiple insecticides on spotted lanternfly adults and assess impacts to grape productivity. Complete field evaluations of ovicide efficacy and submit manuscript on efficacy of malathion on spotted lanternfly egg masses in lab versus field settings. 2.1 Assess movement of SLF from surrounding vegetation and vineyard blocks into experimental (observed) vineyard blocks. 2.2 Develop methodology for rearing of SLF to F1 generation for short term colony establishment. 2.3 Assess individual variation in phloem sampled from Ailanthus altissima (tree of heaven) harboring disparate numbers of feeding SLF. Complete nutrient analyses of field collected SLF to infer feeding requirements of SLF across its life stages. 2.6 Continue experiment attempted to further test potential for transmission of Pierce's disease by adult SLF. 2.7 Complete prediction of metabolic pathways of three bacterial endosymbionts of SLF. Complete description of growing degree day model of female SLF maturation and endosymbiont transmission from bacteriomes to developing eggs. 2.8 Complete and submit manuscript on efficacy of Beauveria bassiana on spotted lanternfly egg masses tested in lab versus field settings. Conduct survey of egg parasitoids of spotted lanternfly in expanded areas of SLF infestation in Virginia. Continue to rear non-target hosts for non-target host suitability studies of the nymphal parasite of SLF, Dryinus sinicus. Test prey choice by predators when alternative prey species are available in addition to SLF. Determine which of the most effective predators display a functional response to SLF density. Evaluate ability of P. maculiventris to reduce damage to grapevines infested with SLF under semi-field conditions. Assess impacts of host switching on ailanthone levels in SLF adults. 3.1 We will continue to work with Extension personnel, primarily at Cornell (including NYS IPM and NE IPM), Rutgers, Virginia Tech., and Penn State to add and update fact sheets and educational materials based on research findings, as they become available. In the upcoming year, this will include improved management recommendations for grape growers based on thresholds established from 3-year study of impacts of SLF nymphal and adult feeding on grapevines conducted by Centinari and Acevedo. 3.2 We will also continue to deliver research and management-based presentations to stakeholders, in person and through virtual meetings and webinars, as we have in previous years. NE IPM will also publish an Insights newsletter issue with an SLF theme, which will highlight accomplishments and management recommendations from the project. Given the proximity of the SLF populations to higher value grape growing regions along Lake Erie in PA and NY, as well as in the Finger Lakes and Long Island regions of NY, we will be holding additional pre-emptive grower meetings with grape growers and cooperatives to improve their preparedness and ability to identify and monitor for SLF. Our first such meeting was held on May 1, 2024 in North East, PA, and included participation by PA Department of Agriculture, NYS IPM, and USDA APHIS. We will hold meetings throughout the next year, as needed, depending on how and where SLF infestations are imminent. 3.3 NE IPM will perform an evaluation of the impacts of the project and needs of the stakeholders using multiple focus groups of stakeholders. These groups will include grape growers and industry members (as these are the most directly and negatively impacted by SLF) as well as other representative stakeholders (e.g., green industry producers/nurseries, state regulators, and others to be determined). Data collected from focus groups will be used to assess how growers perceive SLF risks, the SLF management practices they are willing to adopt, and how perceived risks and vulnerability affect their decision making related to SLF IPM. 3.4 We will continue to mentor and support all early career professionals completing degrees and/or working on any SLF project, to bring projects to completion, and prepare and connect them to the next step in their career trajectories, from the present through to the conclusion of our project period (and likely beyond, if needed, via other funding resources that may be available). 3.5 We will host a webinar on project accomplishments and highlights, to which our Stakeholder Advisory Panel (SAP) will be invited, but will also be open to other stakeholders that have participated in the SLF Summit (which includes regulators from USDA APHIS, state departments of agriculture and the National Pant Board). We will also prepare and disseminate a project report to our SAP. We will then hold a virtual meeting with our SAP near the completion of our project (early summer 2025) to evaluate project accomplishments, remaining needs, lessons learned, and to prioritize potential future work concerning SLF impacts to grapevines.
Impacts What was accomplished under these goals?
1.1 We continued work evaluating impacts of nymphs and adult SLF on Vitis vinifera cultivars to assess effects on grape production parameters, fruit and wine quality, and primary metabolites important for grapevine health. 1.2 We conducted trials of potential ovicides and entomopathogenic fungus against egg masses and hatching nymphs. 1.3 The efficacy of Beauveria bassiana was tested on SLF nymphs (hatched first instars) in vineyard settings; efficacy of malathion and other insecticides continues to be tested in vineyards. 1.5 Additional results testing impacts of insecticides on non-target hosts tested in a previously published study by our group (Keller et al., 2022) continue to be analyzed, as taxonomic work (identification to genus) was performed on pollinators and other captured non-target arthropods (to be published in another paper). 2.1 In PA, we continued evaluating impacts of nymphs and adult SLF on other specialty crops including citrus (Valencia orange), avocado, kiwi fruit, hops, and grape. Results showed nymphs successfully survived feeding an each of these hosts, and while adult SLF did not perform as well (assessed via days of individual survival and mass change over time), adults lived at least 5 days feeding on each host, suggesting these may each be temporary hosts for SLF in field (agricultural) settings. 2.2 In PA, SLF colonies were reared in the laboratory from field collected egg masses. Using potted tree of heaven grown with modifications (developed to maximize sapling growth), SLF were reared successfully through all life stages and egg masses were laid. A paper reporting these results and tree of heaving growing protocol are in preparation. In VA Tech and Penn State, SLF have been successfully reared, at least through early instars, for use in host suitability, EPG, and chemical sequestration studies. 2.3 In PA, we are continuing to perform nutrient analysis (measuring carbohydrate, protein, and lipid levels of wild SLF from sites collected in PA biweekly from early May to end of season 2023. These nutrient levels, with recorded live mass of each sampled SLF will be analyzed and summarized in a paper on SLF nutrient status and fitness. 2.3 Additional EPG waveforms were collected on all life stages of SLF. 2.4 Additional data collection was performed for revisions to a publication on insights from DNA analysis of SLF gut content on dispersal. Additional SLF gut tissue was sampled and female reproductive status was assessed for an additional ~200 individuals to expand the current data set (in response to comments from reviewers on previous manuscript). 2.5 We are continue to develop, and make publicly available, first-principled model of SLF population dynamics and numerical methods for solving partial differential equations. 2.5 We continue to assess and include proximity of rail lines and highways to vineyards to predict risk in models under development. 2.6 · Repeated transmission experiments in grapevines to see if SLF transmitted Pierce's disease. Preliminary results suggest transmission of Pierce's disease (observation of visibly symptomatic plants) but not confirmed detection of Xyllela fastidiosa bacterium (positive qPCR results) for symptomatic plants (was detected in only one plant sample). White paper prepared for non-peer reviewed publication (peer reviewed manuscript pending additional experiment being replicated). 2.7 Specimens collected in 2020-2022 continue to be dissected and growing degree day models computed to predict mating and egg laying. Additional specimens collected from southern-most range of SLF in US (in North Carolina) for comparative computation of degree day estimates for reproductive development and endosymbiont transmission. Additional specimens collected at additional sites in US range of SLF (Kernersville, NC; Nashville, TN; Rochester, NY; and Lewistown, PA) to add to this dataset. 2.8 In DE, we continue to rear a target non-target Hemipteran species (Poblicia fuliginosa (Fulgoridae); Rhynchomitra microrhina, Scolops sulcipes (Dictyopharidae); Flatormenis proxima (Flatidae); Acanalonia conica (Acanaloniidae))to acquire eggs for host specificity testing of spotted lanternfly biocontrol agents.Non-target host suitability work continues for the nymphal parasitoid, Dryinus sinicus, which will be the main target of future work. 2.8. In PA, both Carolina and Chinese mantids, rapid wolf spiders, spined soldier bugs, and wheel bugs continue to be tested for predation of SLF populations of each life stage in enclosed conditions. 3.1 Webinars and in person presentations given by Cornell Cooperative Extension, Penn State Extension, Rutgers Extension, Virginia Tech. Extension (some individual webinars and meetings listed under Products in report. Included SLF in numbered extension publications (annual pest management recommendations, and fact sheets). 3.2 Continued SLF programming/tabling/outreach to the public during Master Gardener programming at public events. Cornell Cooperative Extension, Penn State Extension, Virginia Tech. Extension. 3.2 StopSLF.org website has seen > 30,000 visitors since launching website. NE IPM Center has facilitated video recording of annual SLF Summist and hosts videos on its YouTube channel and at StopSLF.org. We through NYS IPM have engaged with stakeholders from State Departments of Agiculture, USDA APHIS, and other regulatory officials, growers, and Extension educators by hosting the annual 2-day SLF Summit. On-line and in person (2024) SLF Summits held from 2021-2024 were attended by nearly 1800 people from >30 states and Canada. 3.4 All institutions partnering in SCRI grant project continue to train and mentor undergraduate and graduate students, postdoctoral scholars and technicians. 3.5 Across institutions, presented various aspects of SLF management to graduate and undergraduate students (quarantine, potential eradication, chemical control, biocontrol, invasion ecology, plant pathology course, introductory entomology course). We engaged with project stakeholders in the USDA APHIS Technical Working Group meeting in Jan. 2024 and at the in person SLF Summit in Harrisburg in Feb. 2024. Most of the institutions on the current SCRI gave presentations at one or both of these meetings.

What opportunities for training and professional development has the project provided?Temple: Mentored ~15 undergrads on SLF related projects including research skills, modeling, and web development. Mentored and provided professional development for 3 post-docs, 2 graduate students, and 1 research technician. U Del.: This project has supported 2 graduate students - PhD Tyler Hagarty and M.S. Cat Williams - both of whom will finish in 2024. This project has also partly supported undergraduate research by 4 different undergraduate students during the reporting period (one of whom is currently applying for graduate studies) and has leveraged additional support (from Hatch and department sources) for undergraduate research. One of the undergraduates was trained to work in the USDA quarantine facility and conduct behavioral assays of parasitoids using EthoVision software. U RI: SLF working group and the SCRI collaborative research program on biological control as regular meetings and conferences to provide professional development related to the project. Rutgers: PhD student Kasia Madalinska continues to conduct research on SLF feeding, monitoring and management in vineyards. USDA-ARS: Three postdocs working in Leskey lab continue to lead experiments and publish findings. Two of these scientists were hired into full-time scientist positions during the course of the current reporting period. VA Tech: Training for graduate student (now doctoral candidate). Providing student speaking opportunities in conferences. Graduate and undergraduate IPM training Cornell: Undergraduate and graduate students collected data, graduate students analyzed data and wrote publications. Grad students also gave several presentations at meetings and Ag Progress Days. A graduate student from Puerto Rico spent part of the 2023 summer with the Hajek research group, in the lab and field, assisting with conducting studies of insect pathogenic fungi. Penn State: Professional training of 3 undergraduates, 2 MS students, 3 post-doctoral scholars, 3 technicians. Many of these students have co-authored posters or presentations and presented findings at scientific meetings, and have also been mentored in writing publications from their projects. How have the results been disseminated to communities of interest?Results have been presented to other professionals in a variety of formats, but have been primarily through publications in peer-reviewed journals and oral and poster presentations at conferences. Additional outlets include: Via class and seminar presentations Publications, presentations at conferences and for the public and stakeholders (e.g., Cultivate 23, largest hort show in US), Quarterly meetings, press releases, etc. Face-to-face presentations in grower conferences and fruit schools Numbered extension publications (recommendations and fact sheets) Google Group mailing list for grape growers, tree fruit growers, and hop growers) Virginia Fruit web site (with dedicated SLF page) SLF Dashboard (https://iecolab.org/slfDashboard/index.html) has been shared with and updated in communication with state government agencies SCRI Project Website: StopSLF.org ? What do you plan to do during the next reporting period to accomplish the goals?For all aspects of the project, data collection will be completed as needed, and data analyzed and publications prepared and submitted. This includes the following stated projects (but also applies to all project objectives that comprise our major goals): 1.1 Impacts of SLF feeding, focusing on nymphs feeding at various densities, will continue to be monitored in the field on grapevines. 2.3 More EPG waveforms will be recorded that show reduced levels of noise compared to recordings made to date. Histology will be completed for plant tissue samples taken during EPG experiments to verify location of mouthparts and EPG feeding. 2.3 Work will continue on collecting and analyzing nutrient assays to measure the carbohydrate, protein, and lipid levels of individuals in these samples for additional insight into SLF nutrient status and fitness. 2.7 Work on endosymbiont transmission and female reproductive development and growing degree day requirements will continue. 2.8 The 4 expected future manuscripts include two on recruited parasites of SLF, summarizing all work done in this space (i.e., including collections performed by USDA cooperators) and a second manuscript focused on the results of Cat Williams' research on Anastatus reduvii. The remaining two planned publications consider the non-target fulgorid Poblicia fuliginosa - one will consider the life history and rearing of the species and a second will revise the taxonomic status of the species and other members of Poblicia. 2.8 The two graduate students supported on this project are both expected to finish in the fall of 2024. 2.8 Seek additional support to continue the investigation of potential biological control agents (mainly host suitability testing and behavioral assays of the larval parasite Dryinus sinicus in USDA quarantine and the indigenous Anastatus reduvii). For Dryinus sinicus, the needed future includes evaluating the impact of the species on native non-targets (which is a required assessment before a classical biocontrol agent can be released) and continuing to monitor and assess the impacts of the recruited parasite Anastatus reduvii. 2.8. Evaluate selected predators of SLF for a numerical response to determine if any could be used in augmentation biocontrol (spined soldier bugs are a promising candidate). Complete evaluation of how predators respond to SLF prey that have sequestered toxins from tree of heaven. 2.8 Work on any revisions to our submitted manuscript. Continue with discoveries of insect pathogenic fungal species killing spotted lanternflies. Evaluate susceptibility of different ages of adult spotted lanternflies to B. bassiana. Analyze data to describe the epizootiology of fungal diseases of spotted lanternflies. 3.1-3.5 All partnering institutions will continue all aspects of project dissemination to stakeholders.

1.1 We found that 4 years of feeding by SLF reduced tree growth, starch storage in roots, several nutrients, and altered gas exchange measurements in silver maples, willows, river birch, and tree of heaven in multi-tree enclosures during 4 seasons of SLF feeding. 1.1 We continued work evaluating impacts of nymphs and adult SLF on Vitis vinifera cultivars to assess effects on grape production parameters, fruit and wine quality, and primary metabolites important for grapevine health. 1.2 We conducted trials of potential ovicides and entomopathogenic fungus against egg masses and hatching nymphs. 1.4 Published a recommended protocol for quantifying SLF egg masses in uniform sized-plots at several satellite population locations in PA. 1.5. Bark sprays of dinotefuran on tree of heaven performed in summer did not result in sufficient residues in flowers the following summer to be toxic to pollinators. Treatment of red maples with dinotefuran in the fall showed up the following spring in flowers at levels capable of being toxic to solitary bees, but not honey bees.Ovicide and Beauveria trials would allow avoiding bee toxicity if shown to be efficacious against SLF. 2.1. In PA, host suitability and damage by SLF on select specialty crops studies continued on kiwifruit, hops, grape, avocado, and Valencia orange on potted plants/trees. Results showed that although 4th instar SLF could survive well feeding on kiwifruit, hops, grape and avocado, adult SLF could only survive well on grapes, and not any of the other tested specialty crops (Valencia orange trees were only available for adult SLF testing). 2.2 In WV, SLF colonies continue to be reared in the laboratory under optimized conditions. A paper reporting colony establishment and maintenance has been published. In VA Tech and Penn State, SLF have been successfully reared, at least through early instars, for use in host suitability, EPG, and chemical sequestration studies. 2.3 Completed and published a dendrochronological analysis of the impact of SLF feeding on several host tree species. 2.3 In PA We collected wild SLF from 11 sites across PA biweekly from early May to end of season 2023. The live mass was recorded for 20 individuals from each site to be used as a baseline indicator of fitness of wild populations. We began conducting nutrient assays to measure the carbohydrate, protein, and lipid levels of individuals in these samples for additional insight into SLF nutrient status and fitness. 2.3 Additional EPG waveforms were collected on all life stages of SLF. 2.3 Surveyed SLF for temporal host plant preference. 2.4 Additional data collection has been conducted using DNA analysis of SLF gut content to determine dispersal. Manuscript prepared and submitted for publication, and was returned for further data collection and resubmission. 2.5 Developing first-principled model of SLF population dynamics and numerical methods for solving partial differential equations. 2.5 Assessed proximity of rail lines and highways to vineyards to predict risk. 2.6 · Repeated transmission experiments in grapevines to see if SLF transmitted Pierce's disease. ·Preliminary results suggest transmission of Pierce's disease. Analyzed data on experiment to verify the physiological changes of SLF and PD on grapevines, and repeated the experiments adding water deficit as stressor. 2.7 Specimens collected in 2020-2022 continue to be dissected and growing degree day models computed to predict mating and egg laying. Additional specimens collected from southern-most range of SLF in US (in North Carolina) for comparative computation of degree day estimates for reproductive development and endosymbiont transmission. 2.8 In VA, tested whether Beauveria entomopathogen would provide a measure of biological control in field trials. 2.8 In NY, collected species of insect pathogenic fungi discovered killing spotted lanternflies (but previously not known as pathogens of spotted lanterrnfly: 1. Conducted Koch's posulates to prove pathogenicity.2. Deposited cultures in a fungal culture collection (ARSEF, Ithaca NY) so these are available to others and 3. Sequences deposited in GenBank so these are also freely available worldwide. A total of 19 species of insect pathogenic fungi have been identified killing spotted lanternflies. 2.8 In DE, a target list of five non-target Hemipteran species (listed below) was field collected and sustained in rearing cages with plant material to acquire eggs for host specificity testing of spotted lanternfly biocontrol agents. Poblicia fuliginosa (Fulgoridae) (115 field-collected this year) Rhynchomitra microrhina (~43 field-collected this year), Scolops sulcipes (Dictyopharidae) (>60 fields collected this year) Flatormenis proxima (Flatidae) (>100 field-collected this year) Acanalonia conica (Acanaloniidae) (>200 field-collected this year) Non-target host suitability work has just recently begun for the nymphal parasitoid, Dryinus sinicus, which will be the main target of future work.Additionally, field collection of SLF eggs has found significant numbers of the indigenous egg parasite Anastatus reduviireared from field collections of SLF eggs from northern Delaware and adjacent Maryland. In 2022, 95 wasps were obtained from 749 egg masses (39,743 eggs), and in 2023 52 wasps were obtained from 591 egg masses (21,250 eggs), with additional wasps obtained from field collected heteropteran eggs. Behavioral assays are being conducted using Ethovision comparing A. reduvii and A. orientalis behaviors in artificial arenas when presented with SLF or non-target hosts. Along with A. reduvii collections from SLF egg masses, several other microhymenopteran families have been collected by hand over the past field season. These will be used for sequencing in the future. 2.8. In PA, both Carolina and Chinese mantids, rapid wolf spiders, spined soldier bugs, and wheel bugs found to effectively reduce SLF populations of each life stage in enclosed conditions. 3.1 Webinars and in person presentations given by Cornell Cooperative Extension, Penn State Extension, Rutgers Extension, Virginia Tech. Extension (some individual webinars and meetings listed under Products in report.Included SLF in numbered extension publications (annual pest management recommendations, and fact sheets). 3.2 Continued SLF programming/tabling/outreach to the public during Master Gardener programming at public events. Cornell Cooperative Extension, Penn State Extension, Virginia Tech. Extension. 3.2 StopSLF.org website has seen 13,004 visitors during current reporting period. Since launching website (Sept. 1, 2020 - Oct. 31, 2023), website has seen 26,667 visitors.? NE IPM Center has facilitated video recording of annual SLF Summist and hosts videos on its YouTube channel and at StopSLF.org. For most recent Summit held Mar. 1-2, 2023, recordings have seen 697 views. For all SLF videos and SLF Summits (2021-2023) and 4 Spotted Lanternfly Basics webinars, we have seen 4,991 views. 3.3 All institutions participated in SLF working group meeting in Geneva NY to develop research approaches. 3.4 All institutions partnering in SCRI grant project continue to train and mentor undergraduate and graduate students, postdoctoral scholars and technicians. 3.5 Across institutions, presented various aspects of SLF management to graduate and undergraduate students (quarantine, potential eradication, chemical control, biocontrol, invasion ecology, plant pathology course, introductory entomology course). Due to Covid and challenges scheduling our Stakeholder Advisory Panel meeting, we did not have a meeting in early spring with our SAP as planned. However, we did engage with these representatives in the USDA APHIS Technical Working Group meeting in Feb. 2023 held on-line and at the SLF Summit. Most of the institutions on the current SCRI gave presentations at one or both of these meetings.?

Progress 09/01/21 to 08/31/22
Outputs Target Audience:The following target audiences were focused upon in this reporting period: • grape growers and wine grape industry • orchardists and other fruit growers • vegetable growers • Master gardeners • arboricultural and forestry industries • fruit and forest entomologists • graduate and undergraduate students learning about invasive species • homeowners • IPM practitioners • green industry professionals, specifically ornamental growers and nurseries • lawn and landscape managers • members of the general public, including Citizen Scientists participating in various spotted lanternfly projects • local goverernments in the following states: PA, WV, NJ, DE, NY, MD, VA, MA, OH, CT, MA, IN, RI with particular emphasis on Departments of Agriculture (especially the PA Department of Agriculture, NY DEC, and NY Ag and Markets) • industries and shippers in spotted lanternfly quarantine states: PA, WV, VA, NJ, DE, NY, MD • collaborators within the USDA, specifically those working on biological control who are not participants in the current SCRI project • Extension professionals in participating universities and those also in the spotted lanternfly quarantine states and in other concerned states at risk for invasion (i.e., OR, WA, CA, NC) and other countries (Canada, New Zealand) • university researchers at Land Grant and other universities and colleges throughout the US who are concerned about spotted lanternfly • Local county government offices • Undergraduate and graduate students in courses taught by PI and Co-PIs (e.g., > 500 at Penn State, in addition to other universities) • Some non-public schools (e.g., Montessori schools in NY) • policy makers in various government agencies within the USDA such as APHIS, NRCS, ARS, EPA, NIFA • the USDA-OPMP and the pesticide industry to develop insecticide label amendments for spotted lanternfly • agencies that work in collaboration with Northeast IPM (a member of the current grant collaboration) including NE SARE, state IPM coordinators that participate in the multistate project NEERA-1604, HUD, the NE IPM's Advisory Council, and three other regional IPM centers covering the entire US Changes/Problems:Some grant activities, particularly travel to conferences and for working group meetings have not been able to occur due to the Covid-19 pandemic and associated travel restrictions. However, meetings were held virtually and significant progress was made, and we anticipate reduced travel restrictions in the following grant year. At VA Tech, difficulties were encountered due to the locations of SLF infestation. In the initial phases, SLF has been restricted to the most northern part of Virginia. This necessitated a 3.5 hour drive each way to visit sites. We worked in a quarantine facility in Blacksburg for some objectives, but constraints of working in a Q lab greatly restricted the work we could do. This year we arranged to work in a growth room at Alson H Smith Agric and Research and Extension Center, once the infestation zone grew to encompass that part of Frederick County. This problem is decreasing somewhat with the southward expansion of SLF range. At other institutions, identification of study sites has been challenging. We have observed that SLF "move out" of areas with high SLF infestations where experiments have previously been conducted for multiple years. Given the high mobility of SLF across its nymphal instars and adult stages, it is challenging to find and establish new study sites within one field season (i.e., find the new areas of high SLF infestation for a given year). This movement of SLF populations from year to year is likely due to high infestations depleting nutrient resources, at least temporarily, and this hypothesis is now being investigated by several collaborators. What opportunities for training and professional development has the project provided?Temple University project team: hasincluded 8 undergraduates, two graduate students and three postdocs in our research on modeling spotted lanternfly. University of Rhode Island project team:the Spotted Lanternfly working group and the SCRI collaborative research program has regular meetings and conferences to provide professional development related to the project U. Delaware: During the current reporting period, we have employed and trained 2 undergraduates for field collecting and rearing colonies of Fulgoroidea and have recently added an m.s. student (Cat Williams) to investigate the recruitment of egg parasitoids by local SLF. We also have a Ph.D. student (Tyler Hagerty) who is nearing the completion of his degree in an SLF-related project. VA Tech: Professional training of graduate students in degree programs: Pfeiffer - Support of one PhD student: Jason Bielski; Tholl - Training of two PhD students: Brian Ruether and Sukhmanpreet Kaur. Cornell University including NYSYPM program: This project has created regularly scheduled outreach opportunities for extension educators in NYS. Trainings - Monthly updates through NYS IPM. Identify know SLF populations in NYS, treatment progress, etc. Professional development (networking) - connected with local PRISMS and a local grower organization. Put out a call for volunteers to help PRISMS identify and manage SLF infestations. Cornell Entomology: a postdoc has been supported in part by this project. Rutgers University: MS student Kasia Madalinska continues to conduct research on SLF feeding, monitoring and management. USDA: Three post docs working in Leskey lab continue to lead experiments and publish findings. Penn State: Professional training of 5 undergraduates, 5 MS students, 3 PhD students, 3 post-doctoral scholars, 3 technicians. Many of these students have co-authored posters or presentations and presented findings at scientific meetings, and have also been mentored in writing publications from their projects. How have the results been disseminated to communities of interest?The dissemination of project findings is enumerated in the Products and Other Products sections of this report. What do you plan to do during the next reporting period to accomplish the goals?In addition to the dissemination of project findings enumerated in the Products and Other Products sections of this report, the following ways in which results have been disseminated to communities of interest were identified by collaborators at each institution: University of RI: We plan to continue rearing non-target species to provide egg masses and nymphs as required by USDA labs for host range testing of potential SLF parasitoids. With the recent detection of SLF populations in Rhode Island in August of 2022, we plan to collect egg masses in the winter of 2022-2023 to look for egg parasitoids. One native species of interest is Anasatus reduvii, which has been documented to attack SLF egg masses in the Mid-Atlantic states. We also plan to increase efforts to document and rear native parasitoids of planthoppers collected as non-targets for host range tests. We plan to fine tune training tools to better train employees involved in these collections and will expand collections to other parts of Rhode Island and Connecticut not previously explored. U. Delaware: SLF egg collections for biocontrol agent survey (winter-spring 2022-2023). If this effort results in rearing Anastatus reduvii (as was found in the current reporting period), we will partner with USDA and URI to develop a lab colony for further study. Develop molecular resources for Anastatus, especially the COI locus downstream of the barcode region, for all available Anastatus taxa. Continue rearing of fulgoroids for non-target host specificity testing with goals of improving rearing techniques (especially overwintering), and better understanding life history parameters. We plan to publish the life history of Poblicia fuliginosa in the upcoming calendar year. Pursue EthoVision work with Anastatus orientalis and A. reduvii to investigate ecological host range. VA Tech: Will monitor injury as SLF populations develop in Virginia vineyards and orchards. Follow spread through Virginia. Continue work on Beauveria bassiana on SLF ovicidal trials on SLF egg masses. Expand Beauveria trials in greenhouses. Move Beauveria trials into vineyards. Evaluate secondary pests following grower SLF programs at Rutgers University with two different grapes (Traminette and Syrah), supported by Anne Nielsen. Completion of repellency field studies and preparation of manuscript. Potential compound analysis of SLF "hot trees" with Tracy Leskey. Comparative sequestration assays (nymphs and adults) with different secondary compounds from TOH and other SLF host plants; determination of organ specific sequestration; transcriptome analysis of SLF gut and sequestering tissue to identify putative ailanthone transporters (will continue after the end of funding period with no cost extension). Rutgers: In collaboration with VA Tech, conduct vineyard trials: Repellency of lavender oil and CNR-1 will be tested. Continue monitoring of SLF in vineyards in NJ. Continue testing efficacy of environmental DNA monitoring of SLF. USDA: Continue classical biological control studies. Continue testing of host plant suitability and feeding impacts on specialty crops. Continue studies testing entomopathogenic nematodes as biological control agent for SLF. Continue studies of SLF dispersal. Penn State: Verify if SLF transmits PD and elucidate the combined effects of SLF plus PD on grapes. Conduct laboratory analysis (plant tissues and wines) from field experimental trials conducted in 2022. Determine cumulative effects (year-after-year) of SLF feeding on grapevine health, production, fruit, and wine quality. Determine the synergistic or antagonistic effects of SLF feeding damage and pathogens on grapevine plant responses, including plant growth and primary metabolites important for vine health, and gene expression. Complete population dynamics models with 3 full years of egg to adult transitions. Determine the timing and concentrations of sequestered toxins by SLF from tree of heaven and how this impacts a variety of natural enemies by life stage. Continue SLF female reproductive development and endosymbiont transmission characterizations. Conduct nutrient analyses of wild populations of SLF to improve understanding of nutrient requirements and inform rearing of lab colonies. Continue EPG studies of SLF feeding behavior. All Institutions: Deliver management strategies and new knowledge to specialty crop stakeholders via Extension programming. Will provide information in state vineyard and orchard grower meetings. Provide SLF education and outreach using traditional and web-based platforms. Will produce and revise extension publications and fact sheets. Will update as appropriate the SLF section of project websites. Continue support of graduate student research projects. Support graduate student presentations at scientific conferences. Continue graduate student participation in stakeholder meetings.
Impacts What was accomplished under these goals?
1.1. In VA, populations capable of causing injury in vineyards have been assessed.In PA, host suitability and damage by SLF on select specialty crops was investigated for a third year, including hops, pumpkin, strawberry, cucumber, kiwiberry, and grape. We evaluated the impacts of fourth instars or adults confined to a single branch or whole trees on gas exchange attributes, selected nutrients, and diameter growth using young saplings of four host tree species. In PA, we conducted field trials on 2 Vitis vinifera cultivars to assess effects of nymphs and adult SLF density on grape production parameters, fruit and wine quality, and primary metabolites important for plant health. We also conducted a field trial to evaluate if phloem-feeding by adult SLF can alter sugar translocation among above and belowground plant sinks. 1.2. We have conducted trials of Beauveria against SLF egg masses and hatching nymphs, using different formations and treatment timings in VA. In NJ and PA, we have tested Beauveria applications in area wide treatment studies in field plots. 1.3 37 insecticides tested for contact and ingestion activity in 9 different trials on potted grape, peach and tree of heaven at PSU Berks.Developed a 24C label amendment for the use of bifenthrin for SLP control on grapes post-harvest. 1.4 Models for the probability of detection of egg masses, nymphs and adults were developed from three seasons of SLF infestation of satellite populations. A 2year study was completed assessing the efficacy of two commonly used monitoring/trapping methods, sticky bands and circle traps at sites in WV and PA. 1.5. We quantified neonicotinoid residues in whole flowers of red maple and tree-of-heaven treated with post-bloom imidacloprid or dinotefuran applications that differed in timing and method of application. Ecotoxicology of bifenthrin vs. dinotefuran for SLF control was assessed. 2.1. We have used proximity of TOH to communicate risk to grape growers. In VA we observed several grower-modified TOH control tactics. In WV, studies are underway to use DNA analysis of SLF gut content to determine dispersal. 2.2. Develop sustained SLF colonies in the laboratory and under semi-field conditions. In VA, we maintained TOH in lab for SLF rearing, contributing to a journal article.Identified a biological obstacle to growing young TOH in the lab - the eriophyid mite, Aculops ailanthii. In WV, SLF colonies have been reared in the laboratory and conditions optimized, and has been submitted for publication. In PA, SLF have been reared in lab and semi-field conditions for use in host suitability and feeding behavior (EPG) studies. 2.3. In VA, we repeated semi-field trials in July 2022 to assess effects of plant-based repellents on the retention of SLF on potted grape vine. In PA, EPG waveforms were collected on all SLF nymphal instars and adults; histology is underway to verify waveforms. 2.4. In WV, studies are underway to use DNA analysis of SLF gut content to determine dispersal. 2.5. In VA, SLF was followed in railbeds relative to vineyards to determine circumstances of SLF human assisted establishment in a new isolated area. In PA, ongoing development ofmodel of SLF pop. dynamics and numerical methods for solving partial differential equations are underway; ongoing developmentof data science methods and pipeline to identify properities associated with long distance transport and for rapid response are underway. Continued sampling ofSLF pop. genetics across dispersal pathways. 2.6. In PA, we conducted transmission experiments in grapevines to see if SLF transmitted Pierce's disease. We also onducted second year of transmission experiments to see if SLF transmitted grapevine red blotch virus, and grapevine yellows phytoplasma. Preliminary results suggest transmission of grapevine yellows phytoplasma. Completed and published transcriptomics on grapevines exposed to high SLF populations. Conducted experiment to verify the physiological changes of SLF and PD on grapevines. 2.7. Collected SLF adult females weekly from 12 locations across PA. Specimens collected in 2020 and 2021 were imaged and dissected and growing degree day models were computed to predict mating, egg laying. Endosymbiont organ positions included in data recorded in dissections. Analyses are underway. 2.8. In VA, we developed feeding assays to investigate the sequestration of plant-derived semiochemicals in SLF nymphs and adults. Feeding trials with sucrose solutions applied between parafilm membranes were successful for nymphs. Sequestration assays were performed with ailanthone, a predominant quassinoid terpene in tree of heaven. Current research project on entomopathogenic fungi is underway in VA. From a community science project, we obtained >1,000 reports of a broad diversity of generalist predators feeding on SLF adults in the field, including birds and arthropods. Experiments with SLF harboring defensive chemicals acquired from feeding on A. altissima showed that these chemicals are detectable by birds preying on SLF such that they will choose non-Ailanthus fed SLF if given a choice. Biological control In RI and DE, we are collaborating with USDA facilities with potential SLF biocontrol agents in quarantine under the hypothesis that natural enemies would reduce SLF populations to below harmful levels. In RI, we have conducted field collecting trips in Rhode Island to collect non-target insects to begin or maintain rearing laboratory colonies of these species. Rearing protocols have been developed for 28 species. In DE, during the 2022 field season, we collected 752 total SLF egg masses. From these eggs, we reared 32 Anastatus. The preliminary identification (both molecular and morphological) suggests that Anastatus reduvii has been recruited as an SLF parasite. 3.1-3.3. Information is presented in a SLF worker Google Group, and separate Google Groups for grape, orchard, small fruit, and hop growers. Traditional extension publications (posted online) contain current recommendations, including provisional thresholds. VA Tech maintains an SLF web page includes data on recommended materials including class, PHI and seasonal maximum amounts. A recorded presentation is available. Delivery of management solutions is documented in detail in the Products and Other Products sections of this report and summarized on the project's website stopSLF.org. Many are also publicly available at https://extension.psu.edu/spottedlanternfly-management-resources. NEIPM center continues to maintain our SCRI CAP project website, stopSLF.org. Project collaborators participate in the SLF Summit, which is sponsored by the Pennsylvania Department of Agriculture and in 2022 was attended by over 400 audience members throughout the US and Canada. Description of other education, outreach, and stakeholder engagement activities is included in our "Other Outputs" section of this report. 3.4. All institutions partnering on our SCRI grant project continue to train and mentor undergraduate and graduate students, post-doctoral scientists, and technicians. 3.5. In VA, a panel of researchers and grape growers to present SLF progress at Virginia Vineyards Association annual technical meeting. Additional engagement with stakeholders, particularly grape growers, fruit growers, green industry representatives, and other groups, as described in our "Other Outputs" section of this report. Due to travel limitations due to Covid and challenges scheduling our Stakeholder Advisory Panel meeting, we did not have a meeting in early spring 2022 with our SAP as planned. However, we did engage with these representatives in the USDA APHIS SLF Technical Working Group reporting meeting held in Jan. 2022 online at which each institution in our SCRI project gave a presentation of their research findings. We also were able to engage with members of our SAP at the SLF Summit where most of the institution on our SCRI presented their findings.

However, significant progress was achieved in this reporting period despite these limitations. What opportunities for training and professional development has the project provided?Cornell: NYSIPM Program: This project has created regularly scheduled outreach opportunities for extension educators in NYS. Cornell Cooperative Extension of Ulster County: James O'Connell Trainings - Monthly updates through NYS IPM. Identify know SLF populations in NYS, treatment progress, etc. Professional development (networking) - connected with local PRISMS and a local grower organization. Put out a call for volunteers to help PRISMS identify and manage SLF infestations. Cornell University: Postdoc Eric Clifton has been supported in part by this project. University of Rhode Island: URI personnel have participated in the SLF working group and the SCRI collaborative research program in its regular meetings and conferences. Temple: Mentored >10 ungrads on projects related to our modeling and web app development. University of Delaware: Graduate student Tyler Hagerty has received training in molecular sequencing and bioinformatics under Yunke Wu at the USDA Otis lab. Graduate student Tyler Hagerty and undergraduate Cat Williams have received training in USDA BIIRU quarantine protocols (including 40 hours of in-quarantine experience) to conduct ethovision studies on the behavior of Anastatus orientalis when presented with chemical cues of SLF vs non-target hemipterians. Cat Williams is planning to pursue graduate studies focused on SLF biocontrol. VA Tech: Partipated in in-service training for Virginia Cooperative Extension agents. Participated in grower education meetings. 2 graduate students (Entomology and Bio. Sciences) are involved with this project and is critical for their professional development. Rutgers University: MS student Kasia Madalinska continues to conduct research on SLF feeding, monitoring and management. USDA: Two post docs working in Leskey lab continue to lead experiments and publish findings. Penn State: Trained 1 undergrad, 1 PhD student and 1 postdoc in Horticulture; MS student in Plant Pathology; 2 PhD students and 2MS students in Entomology; 2postdocs in Entomology. How have the results been disseminated to communities of interest?In addition to the dissemination of project findings enumerated in the Products and Other Products sections of this report, the following ways in which results have been disseminated to communities of interest were identified by collaborators at each institution: Cornell NEIPM Center: a)Maintained the SLF-Research list and the general audience SLF list. b)The SAP meeting and SLF Summit notes were compiled and disseminated through the SLF-Research lyris list. There are 118 people on that list. The recordings and notes are also posted on the Stop.SLF.org meetings and presentations page with agenda and notes. Cornell NYSIPM Program: We established a listserv that's a venue for sharing of SLF information, primarily in NYS. The listserve now has over 100 members. Cornell Cooperative Extension of Ulster County: Initial contact was through CCEUC Director Jared Buono who spoke with county officials at a meeting. Follow up to this meeting, explaining SLF and its possible impact on Ulster County agriculture was through Zoom. An attendee at a CCEUC conference works at a Montessori school. O'Connell will reach out and attempt to schedule a classroom learning event. University of Rhode Island: URI has featured several of the non-target species being studied on their social media pages as "insect of the week" posts and story updates, as well as highlighting SLF and the biocontrol research. URI biocontrol has 469 followers on Instagram and 188 on Facebook. Updates on the research project are also included on the URI biocontrol lab website. All outreach presentations given by professional staff on SLF include information about the biocontrol research being conducted by the research group involved in goal 2.8. Virginia Tech: Presented in winter and summer Technical Meetings of the Virginia Vineyard Association. Presented material in annual series of orchard fruit schools. Added SLF material to management guides. Updated as needed SLF page in Virginia Fruit web site. Rugters University: The NJAES factsheet is regularly updated with information and SLF-specific Blog posts continue to be electronically posted and delivered to all subscribers. USDA: Discussions continue to be held with Dr. Hannah Broadley and Dr. Juli Gould at the USDA APHIS laboratory on working collaboratively on byicontrol using the dryinid parasitoid as well as Anastatus orientalis. Collaborations and presentations to audiences in regions where SLF has not yet gotten established (Australia, New Zealand, California) continue. Temple University: Continue engaging undergraduate students in mentoring opportunities; continue updating website and web apps with new research findings and tools. Penn State: Continued updating of Penn State Extension SLF website, publucations, presentations to Extension Educators, impacted growers, communications with state departments of agriculture and APHIS. Continued interviews with various media outlets as requested (e.g, NPR Science Friday, various newspaper articles -- summarized on StopSLF.org). What do you plan to do during the next reporting period to accomplish the goals?All collaborators will continue to follow up on findings achieved to date and publish findings in journals and other outlets as appropriate; project collaborators also identified the following plans for the next reporting period. Cornell NYSIPM Program: We will assist with the organization and facilitation of the 2022 SLF Summit. In 2022 we'll be working closer with horticulture specialists in NYS as we anticipate SLF may be found in fields next growing season. D. Olmstead will provide training and professional development opportunities in 2022 for project leaders and collaborators. Self-serve online resources will also be published in early 2022 for Extension professionals and the general public to quickly get started with the spotted lanternfly model. Once project leaders and collaborators are familiar with the spotted lanternfly life stage tracking model in 2022, targeted outreach and extension can be directly achieved through the use of this public online resource that is available free of charge. Cornell Cooperative Extension of Ulster County: Further outreach to Ulster County government - possible trainings with personnel In person trainings for general public on identifying and reporting SLF. University of Rhode Island: We plan to continue rearing non-target species to provide egg masses and nymphs as required by collaborating USDA labs for host range testing of potential SLF parasitoids. We will record our progress and send insects for testing as requested. As no-choice tests are completed and any species are found to have been parasitized by the biocontrol agents we will then provide non-target insects to allow choice tests to be conducted. Temple: Finalize and submit papers on 1) model of SLF population dynamics, 2) long-distance dispersal identification, 3) pest data science pipeline. University of Delaware: Collect SLF and related egg collections for biocontrol agent survey (winter-spring 2021-2022) Conduct microhymenoptera with Eupelmidae as focal taxon for molecular studies directed at identifying indigenous parasites that might attack SLF. Continue rearing of non-target Hemiptera with goals of improving rearing techniques, better understand life history parameters and providing needed life stages to USDA for non target host specificity testing. Continue ethovision studies to better understand A. orientalis orientation behaviors with respect to SLF and focal non-target Hemiptera. Virginia Tech: Continue ovicidal work, comparing effect of application timing. Continue work on B. bassiana. Implement and refine existing tools for monitoring, particularly trapping in areas near vineyards. Assess host plant suitability. Continue work on rearing to develop lab colonies. Continue to examine feeding behavior and repellence. Examine potential SLF management with biocontrol; determine organ specific sequestration of ailanthone in SLF nymphs and adults and determine effects of SLF palatability by natural predators. Will begin identifying potential protein binding factors or transporters for ailanthone. Determine parasitoid emergence from SLF egg masses. Continue to contribute to NEIPMC site; provide SLF education and outreach opportunities; train the next generation of scientists and Extension educators. USDA: Continue work with USDA APHIS collaborators to further develop rearing capabilities for non-target native host species to provide them with host specificity testing of the dryinid parasite and the Anastatus orientalis parasitoid. Continue to rear SLF lab colonies and determine host suitability and impacts of feeding. Continue development and efficacy testing of trapping methods. Continue evaluating SLF attraction to plant volatiles. Rutgers University: Continue monitoring SLF movement and dispersal in and near vineyards. Penn State: Continued studies of SLF feeding on grapevine health, production, fruit and wine quality; Continued study of impacts of SLF feeding on physiology of ornamental trees. Continued laboratory analysis of primay and secondary plant metabolites from field experimental trials conducted in 2021. Determine synergistic or antagonistic effects of SLF feeding damage and pathogens on grapevine plant responses, including plant growth and primary metabolites important for vine health and gene expression. Verify if pathogen transmission experiments were successful; complete analysis of grape transcriptome from 2021 study. Work will continue on modeling degree day requirements for SLF female reproductions. Characterization of endosymbiont transmission stages will continue. EPG studies of all active SLF stages will be conduted. Histology will be performed to verify what aspects of SLF feeding each waveform type is indicating based on fine scale examination of position of SLF stylets in plant tissue, to arrive at a "wave form library." Continue assessing impact of various insecticides on non-target arthropods.
Impacts What was accomplished under these goals?
1.1 Weekly surveys of vineyards and adjacent areas were conducted in NJ and VA to detect presence and level of infestation of SLF in commercial vineyards throughout the season. Key vineyards were scouted by NYS IPM in NY in close proximity to known NY infestations to detect presence of SLF. Completed and published dendrochronology study on SLF feeding on trees. Wood growth hindered by SLF, protected by dinotefuran. In PA,host suitability and damage by SLF on select specialty crops was investigated for second year, including peach, hops, raspberry, cucumber, fig, kiwiberry, and 3 grape varieties. Impact of SLF feeding on physiology of ornamental trees was assessed common garden to determine impact of varying feeding densities of SLF on tree gas exchange, photosynthesis and transpiration rates. Conducted field trials on 2 Vitis species to assess effects of SLF density on fruit and wine quality, and primary metabolites important for plant health. Conducted field trial to evaluate if SLF can alter sugar translocation among plant sinks; data currently being analyzed. 1.2 20 insecticides for control of SLF nymphs and adults were tested in 6 trials on potted peach and tree of heaven. Efficacy of Beauveria bassiana continues to be tested across all SLF life stages in lab and semi-field settings. 1.3, 1.5 Large plot trials were used to test 2 formulations of B. bassiana and dinotefuran against nymphs and adults using helicopter, ultra-low volume backpack sprayers and hydraulic handgun applications. 1.4 Multiple trap designswere used to monitor for SLF in the field in PA and WV. Field trials testing variations in eDNA survey methodology were conducted. 1.5 Large plot trials were conducted to evaluate the pyrethroid bifenthrin vs. dinotefuran using truck mounted ULF mist sparyers. Efficacy against SLF was poor but remains under analysis; impacts on non-targets is under evaluation. Insecticide-impregnated netting was tested for 2nd year on a 13-foot flight intercept barrier along a vineyard to test efficacy in preventing SLF from flying in from the surrounding landscape. Vetagaard Inseticide Netting was tested in a NJ vineyard for post-harvest application. Dispersal into the vineyard was measured by marking and tracking adult SLF. 2.1. Movement on various host plants and into vineyards monitored in VA, NJ, WV, and PA. 2.2 Methods to improve rearing of SLF in lab underway in VA, MD, PA quarantine facilities. 2.3. Testing of plant-derived repellents contines (Tholl & Ruether together with Leskey & Nixon and ArborJet). EPG waveforms successfully collected for adult SLF; histology underway to verify waveforms. 2.5 Developing first-principled model of SLF pop. dynamics and numerical methods for solving partial differential equations; developing data science methods and pipeline to identify properities associated with long distance transport and for rapid response. Sampled SLF pop. genetics across dispersal pathways. SLF life stage tracking model is complete and will be available for use and further testing at https://newa.cornell.edu/spotted-lanternfly Dec. 1. Prelim. analysis of degree day requirements will be used to validate model. 2.6 Conducted transmission experiments in grapevines to see if SLF transmit pathogens. Prelim. results suggest transmission of grapevine yellows phytoplasma. Conducted transcriptomics study to compare gene expression of grapes exposed to high SLF feeding. 2.7 Collected SLF adult females weekly from multiple locations. Dissected 160 additional SLF females and growing degree day models are being developed to predict mating, egg laying. Endosymbiont organ positions included in data collected with dissections. 2.8 Methods, bioassays, genetic diversity of fungal pathogens B. bassiana and Batkoa major being examined. Two new fungal pathogens detected. Non-targets collected for biocontrol studies in RI, CT, NY. Rearing methods developed for 20 species. Potential control parasitoid Anastatus orientalis found to consist of 4 haplotypes; A. orientalis and Dryinus sinicus continue to be studied and tested for non-target impacts in lab. SLF egg masses collected and scanned via X-ray imaging and no parasitoids found; nymphs collected and examined for D. sinicus. 3.1 - 3.3 Delivery of management solutions is documented in detail in the Products and Other Products sections of this report and summarized on the project's website stopSLF.org. Many are also publicly available at https://extension.psu.edu/spotted-lanternfly-management-resources. VA Tech website updated with new SLF pest management guides. 3.1 NYS IPM website updated to include insecticides appropriate for management of SLF in NY. 3.2 NEIPM Center supported SLF SCRI stakeholder meeting with notes, polling, webinar recording; supported SLF Summit with notes and polling; maintained StopSLF.org website. 3.3 NEIPM updated SLF impact statement and shared with Penn State Director of Extension. Made progress on evaluating economic, environmental, human health impacts associated with SLF IPM management techniques, focusing on pesticide application in PA and NY. 3.5A pre-seasonSAP update zoom meetingwas held in April2021to update our SAP on the current status of the SLF invasion and affected crops and summarize 2021research plans.

Progress 09/01/19 to 08/31/20
Outputs Target Audience:The following target audiences were focused upon in this reporting period: grape growers and wine grape industry orchardists and other fruit growers vegetable growers Master gardeners arboricultural and forestry industries fruit and forest entomologists graduate and undergraduate students learning about invasive species homeowners IPM practitioners green industry professionals, specifically ornamental growers and nurseries lawn and landscape managers members of the general public, including Citizen Scientists participating in various spotted lanternfly projects local goverernments in the following states: PA, WV, NJ, DE, NY, MD, VA, MA, OH, with particular emphasis on Departments of Agriculture (especially the PA Department of Agriculture, NY DEC, andNY Ag and Markets) industries and shippers in spotted lanternfly quarantine states: PA, WV, VA, NJ, DE, NY, MD collaborators within the USDA, specifically those working on biological control who are not participants in the current SCRI project Extension professionals in participating universities and those also in the spotted lanternfly quarantine states and in other concerned states at risk for invasion (i.e., MD, MA, OH, OR, WA, CA, NC) university researchers at Land Grant and other universities and colleges throughout the US who are concerned about spotted lanternfly policy makers in various government agencies within the USDA such as APHIS, NRCS, ARS, EPA, NIFA the USDA-OPMP and the pesticide industry to develop insecticide label amendments for spotted lanternfly agencies that work in collaboration with Northeast IPM (a member of the current grant collaboration) including NE SARE, state IPM coordinators that participate in the multistate project NEERA-1604, HUD, the NE IPM's Advisory Council, and three other regional IPM centers covering the entire US Changes/Problems:Various lab and field studies that were planned for 2020 were partially delayed due to Covid travel restrictions and Covid associated lab and univeristy closures. Overall, however, significant progress was achieved despite these limitations. With respect toGoal 2.8: Foreign exploration could not be conducted during 2020 due to Covid travel restrictions (either by US coPI & staff or by Asian cooperators), but in-house research was conducted with natural enemies already in US culture. With the assistance of APHIS cooperators, we initiated non-target testing of the egg parasitoid Anastatus orientalis. We also pursued efforts to obtain live material for lab culture of the nymphal parasitoid Dryinus sinicus, and we worked with Asian cooperators and other taxonomic specialists in the U.S. and Italy to confirm the correct identity of D. sinicus. With respect to Goal 2.6: One international postdoctoral scientist to whom a job offer to work on this project was made last spring, can not join our team until July 2021 because of VISA's issue due to the COVID-19 pandemic. The pandemic has also slowed down the exchange of infected material requested to other universities to conduct transmission experiments in 2.6.? What opportunities for training and professional development has the project provided?All collaborators in the current SLF SCRI project participated in a SLF research symposium that was held on May 15, 2020. This symposium was virtual and created due to the cancellation of other entomology and specialty crop-based conferences (due to COVID-19). The symposium allowed for presentation experience among young professionals and exposure to our project team to connect and collaborate. In addition to the SLF symposium, and 4 virtual meetings focused on reporting progress on, and plans for, work on all project objectives, the following opportunities for training and professional development were identified by collaborators at each institution. Rutgers University: Two students were trained in SLF identification and monitoring techniques through the Rutgers Fruit IPM program A M.S. student, Kasia Madalinska began research on SLF stage specific feeding, monitoring, and management. Ms. Madalinska is being trained on sampling and management tactics as well as statistical analysis. She has also been active in extension activities for SLF in wine grapes. Postdoctoral associate, Donnie Peterson was hired and began studies on eDNA for SLF. Dr. Peterson has been trained on qPCR and other lab techniques associated with eDNA lanternfly surveys, as well as statistical routines needed to analyze resultant data. Cornell University: We began a virtual 'Morning Brew' 6AM meeting this spring to provide tree fruit growers and extension specialists with the opportunity for weekly state-wide discussions on relevant pest management issues that included SLF sightings in NYS. We began planning for outreach and development training for the agricultural community in the lower Hudson Valley via virtual Zoom for 2021. University of Rhode Island: The Spotted Lanternfly working group and the SCRI collaborative research program has regular meetings and conferences to provide professional development related to the project. URI personnel presented and participated in the virtual SLF research symposium that was held on May 15, 2020. Virginia Tech: The project has supported presentations at our annual orchard fruit schools, the main educational venue for tree fruit growers. It also supported presentations for the Virginia Vineyard Association. Two graduate students are involved with this project, critical to their professional development. We support are training/certification program that is integral to Virginia's quarantine program. Students in our graduate pest management course carry out a class project. This involves creating a draft extension fact sheet and a recorded presentation. Two of the seven students in fall 2020 selected spotted lanternfly as their subject. University of Delaware: A graduate student was trained in the use of a mounted camera and EthoVision software for behavioral assays of the behavior of parasitoids in response to chemical traces left behind by potential host species. Temple University: A postdoctoral scientist is being trained on modeling spread of SLF, working in collaboration with Matthew Helmus and all associated members of the Temple modeling and forecasting team. USDA: One ARS postdoc (primarily employed for BMSB) spent ca. 10% of his time assisting a Univ. Delaware graduate student with biocontrol research on lanternfly. A visiting graduate student from Italy also spent some of his time conducting behavioral research with the egg parasitoid, also in conjunction with the ARS postdoc. Several talks were presented by these students and the postdoc based on their work to various interest groups. Two post-docs will be joining the project in 2021 in Leskey Lab, one funded by SCRI and one funded through cooperative agreement with Virginia Tech. Penn State: The project has facilitated the training of two postdoctoral researchers in incisive experimental design with Tom Baker, and the logical progression of experiments stemming from successive experimental findings, and the processing and analysis of video-recorded motion-behavior providing complex behavioral interpretations that require well-developed writing and oral communication skills. Fang Zhu served as Faculty Member of EnvironMentors for one high school student and one undergraduate student, National Council for Science and Environment, Penn State Chapter during September 2019 to May 2020. Students worked on Environmental impacts of pesticides used for Spotted Lanternfly control in Dr. Zhu's lab and gave an oral presentation in Virtual S.T.E.M. SHOWCASE in May 2020. In Greg Krawczyk's lab, three undergraduate students participated in research activities during summer related to SLF activities: Phineas Shaum (PSU undergraduate), Cole Taylor (Wilson College undergraduate), Bradley Filler (University of Pittsburgh undergraduate) A M.S. student, in entomology started his thesis research on non-target effects of insecticides used to control SLF in large-scale forest and ornamental area in the summer of 2019 and is co-advised by Drs. Biddinger & Hoover. APh.D. student is working with Dr. Biddinger whose thesis is understanding the susceptibility of honey bees and Osmia bees to field realistic doses found in plant nectar and pollen after insecticide applications and with targeted bioassays for imidacloprid and dinotefuron. One M.S. student started her degree with Co-PIs Centinari and Rosa and is working on SLF transmission of plant pathogens. One M.S. student started her Entomology degree with PI Urban working on SLF behavior and female reproductive development. EPG refresher training was taken (remotely) during Nov 2020 for early career professional Co-PI Sattar. Training provided by Dr. Elaine Backus. This project has provided training opportunities for a Plant Science Ph.D. student (Andrew Harner). Andrew was trained on the use of eco-physiological equipment and related data analysis and laboratory protocols for identification and quantification of metabolic compounds. How have the results been disseminated to communities of interest?In addition to the dissemination of project findings enumerated in the Products and Other Products sections of this report, the following ways in which results have been disseminated to communities of interest were identified by collaborators at each institution. Rutgers University: The NJAES factsheet was updated with relevant information (https://njaes.rutgers.edu/spotted-lanternfly/) and SLF-specific blog posts on Rutgers Plant Pest Advisory were electronically posted in June and August and delivered to all subscribers. Due to COVID restrictions, farm visits to grower cooperators or those within the Rutgers IPM program were performed individually or with proper social distancing protocols in place. Monitoring for SLF took place at three commercial vineyards and the surrounding woodlots resulting in 18 on-farm visits. Two management projects were conducted on-farm with a grower cooperator in northern NJ resulting in 36 on-farm visits. The Rutgers Fruit IPM program had 490 individual grower reports, 112 one-on-one consultations, and 9 electronic newsletter articles through which they conveyed monitoring results. Through the Rutgers Fruit IPM scouting program, 7 grower twilight meetings, and blog posts we were able to provide up-to-date information on SLF activity, pressure, and management strategies to our target fruit producer audience. University of Rhode Island: URI has featured several of the non-target species on their social media pages as "insect of the week" posts and story updates. URI biocontrol has 258 followers on Instagram and 90 on Facebook. All outreach presentations given by professional staff on Spotted Lanternfly include information about the biocontrol research that is being conducted as one component of this project, and the University of Rhode Island's contributions to it. VA Tech: Our data contribute to refereed journal articles. We have created 4 extension fact sheets, three of which have been translated into Spanish. A page in the Virginia Fruit web site is updated regularly. We contribute to the Virginia Cooperative Extension SLF web site. Information on SLF is disseminated through a blog, and via Pfeiffer's Google Groups for tree fruits, grapes, berry crops, and hops. Extension talks are provided for orchardists and vineyard industry. Results are disseminated in undergraduate and graduate pest management courses. University of Delaware: Open communication (via email and conference calls) with the USDA-APHIS Buzzards Bay and the USDA-ARS Newark facilities was maintained during this research to help with collaboration and dissemination of information and progress. A presentation was given on the EthoVision research at the USDA Interagency Forum on Invasive Species, and on rearing the non-target host-suitability focal species at the Spotted lanternfly virtual symposium. In addition, Tyler Hagerty was interviewed for a video for the Delaware State Parks on September 10th, 2020 and for the University of Delaware student newspaper (The Review) for an article entitles "Spotted lanternflies: a beautiful yet voracious pest" (September 18, 2020). Temple University: Temple University has been in regular communication with the Philadelphia Department of Parks and Recreation to help inform management of SLF in urban areas within the city. Matt Helmus and Julie Urban (Penn State) were interviewed in an article published in the New York Times on SLF. USDA: Discussions with Dr. Hannah Broadley and Dr. Juli Gould (USDA APHIS Otis Laboratory) who are working on biocontrol using the dryinid parasitoid lead to the conclusion that they can collect egg masses of SLF from the field so mass rearing is not essential, but essential assistance is needed to rear several non-target species for host specificity studies. Conference presentations on SLF biocontrol research and related subjects (identifying and rearing non target species needed for host range testing) were presented at the Nov. 2019 national ESA meeting in St. Louis and in Nov. 2020 (virtual meeting), the USDA Invasive Species Forum in Jan. 2020 in Annapolis, as updates within several talks presented in Feb. 2020 by the co-PI in Australia to CSIRO and New Zealand to Plant & Food Research and other regulatory audiences. Presented at USDA Invasive Species Forum in 2020. Penn State: Research updates and recorded webinars and meetings are regularly posted on our project website, StopSLF.org. This website is shared both with members of the interested public, growers, and our SAP. Management guides and basic factsheets have been updated with information generated from the SCRI project across all of our institutions. Many of these factsheets can be found here: https://extension.psu.edu/spotted-lanternfly-management-resources. Presented at the USDA Invasive Species Forum in 2020. Organized (co-organized by Hoover and Urban) and presented findings at a SLF Symposium at the Entomological Society of America Annual Meeting in Nov. 2019. Second annual meeting of the SLF Working Group Workshop and Early Career Professionals Virtual SLF Research Symposium organized by PI Urban and Co-PD Leach. Weekly lab meetings in Co-PI Rosa's research group. Undergraduate courses (50+students/year) with Co-PI Rosa as instructor. The results have been disseminated in the form of presentations to wine grape growers groups and academic community at extension meetings and webinars. Newspapers throughout Pennsylvania that published summaries of many aspects of SLF research and associated findings and the College of Agriculture's communications department has issued numerous press releases and stories about Penn State's work on SLF (some of these are posted on stopSLF.org or at https://extension.psu.edu/spotted-lanternfly). Extension activities (primarily presentations and grower talks) delivered either in person or virtually by numerous Penn State collaborators (Leach, Centinari, Baker, Hoover, Krawczyk, Biddinger, Urban). What do you plan to do during the next reporting period to accomplish the goals?In addition to continuing to follow up on findings achieved to date, project collaborators identified the following plans for the next reporting period: Rutgers: 1.3 Repeat and revise management trials as needed 1.4 Implement, test, and refine existing tools for biosurveillance and monitoring; complete all eDNA methodological field trials, analyze resultant data, and disseminate results via publication, conference presentations, and web-based instructional materials; Continue monitoring using the circle trap; write up manuscript on the distribution of egg masses for peer-review 2.1 Repeat study on the influence of host plant on cohort development and survivorship 3.1Continue Rutgers Fruit IPM program scouting efforts 3.2 Continue grower meetings on SLF biology and management 3.4 Continue training of students and researchers Cornell: 1.1Continue research,using injection technologies; surveying for SLF in the Hudson Valley; and outreach.

Impacts What was accomplished under these goals?
1.1 Weekly surveys of vineyards and adjacent areas were conducted in PA to detect presence and level of infestation of SLF in commercial vineyards throughout the season. Surveys were conducted for in commercial fruit orchard and adjacent areas in PA to detect the presence of SLF nymphs and adults. Bi-weekly surveys for SLF was conducted in Wayne county NY in apple, grape, sumac, and maple at six orchards from 8/12-9/25, 2020. A. altissima were located and scouted for SLF in 18 sites in NY in four counties where SLF had been previously detected. In VA, tree cores and dendrochronology were used to assess SLF feeding damage to A. altissima, black walnut, red maple, and tulip poplar. In PA. host suitability and damage by SLF on select specialty crops was investigated, including peach, hops, raspberry, cucumber, fig, avocado, and kiwi. Impact of SLF feeding on physiology of ornamental trees was assessed in two experiments. Tree response measurements were taken on photosynthesis rate, water efficiency, and gas exchange. Impact of SLF feeding on production, physiology and health was assessed in two experiments in which SLF was enclosed on two varieties of grape. Multiple trap designs, with and without lures, were used to monitor for SLF in the field in PA. 1.2 Insecticide bioassays were conducted on SLF eggs and early instar nymphs in lab testing efficacy of neonicotinoids, bio-rational products (oils and soaps), and nets with incorporated insecticides. 1.3 Lab tested compounds for eggs and nymphs were tested in field conditions. In potted peach, grape, A. altissima, and sunflower, 60 foliar-applied insecticides were tested. Results informed 2 (ee) label amendments for 15 insecticides that added SLF to list of pests controlled. 12 bioinsecticides using strains of Beauveria bassiana and Isaria fumerosa were tested against SLF nymphs and adults on potted plants. In a NJ vineyard, BoteGHA applied via airblast or CO2 sprayer was tested against early instar nymphs. A residual efficacy insecticide trial was carried out in a PA vineyard testing 8 products in 4 chemical classes, and at variable rates of products. Border spray applications of insecticide using a cannon-style sprayer were compared to every row application for controlling SLF in vineyards. This can be used in numerous crops to control the edges where SLF populations are highest. Insecticide-impregnated netting was installed on a 13-foot flight intercept barrier along a vineyard to test efficacy in preventing SLF from flying in from the surrounding landscape. Over the row exclusion netting was deployed in vineyards to exclude SLF from infesting grapevines across 5 different vineyards and compared to uncovered grapevines. Effects on number of needed pesticide applications between treatments was tracked. Tree injection delivery of dinotefuran was tested in urban areas. Long term efficacy of 5 months was observed for treated willow. Vetagaard Inseticide Netting was tested in a NJ vineyard for post-harvest application. Dispersal into the vineyard was measured by marking and tracking adult SLF. 1.4 Field trials testing variations in eDNA survey methodology were conducted. Landscape factors influencing egg mass abundance in wooded habitats around vineyards in NJ was conducted. A trapping studied was carried out in PA using funnel-style circle traps on 5 different hosts within a SLF infested area across each life stage. In VA, several trap designs were compared including sticky bands, and Circle traps. A student has begun research on plant semiochemicals and SLF. In PA, prototype telephone poles used behavioral 'visual traps' were established and monitored for efficacy. 1.5 Evaluations of red maple trees treated in 2019 for SLF by trunk injection or soil drenches of imidacloprid or dinotefuron were tested for persistence of residues in flowers the following spring. Non-target effects two rates of B. bassiana were evaluated two field trials found no significant non-target effects on other arthropods such as bees. 2.1. Same-aged nymphal cohorts were placed on black walnut, red maple, Ailanthus, or grape to test influence of hosts on development and survival of nymphs. Weather conditions caused high mortality for first instars overall. Development was much lower on red maple than on other host plants. Drafting MS of suitability of wild and specialty crop hosts for SLF. Development and fitness of SLF with and without access to A. altissima was tested in 2 generations of SLF. Documented 2019 and 2020 SLF seasonal phenology in Winchester, VA. Calculated the cumulative average growing degree days for each life stage per year. 2.2 Tested a SLF rearing protocol in Virginia Tech's quarantine laboratory using three types of tree-of-heaven cuttings as a food source. Develop sustained SLF colonies in the laboratory and under semi-field conditions at Fort Detrick, MD. Writing manuscript detailing laboratory rearing of SLF. 2.3. Tested the repellent effect of lavender oil in a pilot semi-field trial by monitoring retention and movement of SLF adults on TOH and grape (Tholl & Ruether together with Leskey & Nixon). Retention of SLF was higher on TOH than grape but not significantly different in the presence or absence of the oil. AC-DC EPG equipment acquired and installed in quarantine laboratory at Penn State University Park. Feeding behavior recorded for SLF 2 and 4th instars on A. altissima. 2.4 Manuscript reporting results of a mark, release, re-sight study of SLF published. 2.5 Flight capacity (measuring distance and duration of flight) of free and tethered SLF adults tested in lab and field. Five spotted lanternfly life stage observational datasets were analyzed to estimate percentage emergence for reported days of year 5%, 25%, 50%, 75%, and 95% life stage emergence. In VA we have found that SLF may be associated with TOH along rail lines. 2.6 Helped a former grad student perform an experiment assessing if SLF can vector a plant pathogen between tree-of-heaven in a lab setting APHIS permits were obtained to import plant pathogens (Xylella fastidiosa, Grape Yellows and Grapevine red blotch virus) for transmission experiments. Identified vineyards for transmission studies grapevine red blotch virus grape yellows phytoplasmas, and grapevine leafroll virus. Grafted potted healthy grapevines with virus infected buds to obtain infected plants suitable for transmission experiments in controlled conditions. 2.7 Collected SLF adult females weekly from multiple locations. Dissected over 200 females to identify developmental changes in insects and endosymbionts. 2.8 Non-target testing conducted for egg parasitoid Anastatus orientalis. We also pursued efforts to obtain live material for lab culture of the nymphal parasitoid Dryinus sinicus. Eight possible non-target Hemipteran species (planthoppers and close relatives) were collected and sustained in rearing cages for host specificity testing of spotted lanternfly biocontrol agents. Host suitability tests were conducted with Heteroptera and found parasitism in the squash bug Anasa tristis, 5 species of stink bug and the moth Anthereae polyphemus. Of 23 species included in the potential non-targets list, 21 species have been successfully in located and collected and are being reared for non-target testing. 3.1 - 3.3 Delivery of management solutions is documented in detail in the Products and Other Products sections of this report and summarized on the project's website stopSLF.org. 3.4 A student and young professional based symposium was held in May 2020 to report on current and past SLF research projects. Much of these projects are serving as baseline data and platforms to extend research supported by the SCRI. 3.5 An end-of-season SAP update call was held in October 2020 to update our SAP on the current status of the SLF invasion and affected crops and summarize 2020 research progress.
