Non Technical Summary
Since its first detection in 2008, spotted-wing drosophila (SWD),Drosophila suzukii(Matsumura), has become a keystone pest of small- and stone-fruits in the United States valued at $5.8 billion. Our team made substantial progress by refining monitoring tools, developing effective insecticide-based management programs, cultural controls, and screening native and exotic biological control agents to address the crisis phase of SWD invasion. However, SWD management is still highly insecticide-dependent and is further challenged by secondary pest outbreaks, insecticide resistance, and increased input costs. Now that SWD is established as a keystone pest in the U.S., it is critical to develop more sustainable strategies to manageSWD. Thus,goal of this project is to implement systems-based integrated management programs that are cost-effective and environmentally-sustainable for long-term management of SWD. Major objectives of this project include: 1) Implementation of best management programs for sustainable SWD management in collaboration with grower influencers;2)Develop economics-based decision aid tools to increase profitability; 3) Evaluate sustainable alternatives to insecticides for long-term SWD management;4) Assess and reduce the risk of insecticide resistance development; and 5)Develop and disseminate actionable recommendations that enable producers to optimize pest management decisions, and evaluate their impact.This stakeholder-driven transdisciplinary project addresses SCRI program focus areas: 2) Pest Management; 3) Plant Production and Production Efficiency; 4) New Innovations and Technology; and 5) Food Safety. Grower-stakeholders were engaged to develop objectives of this proposal and will continue to play central role through Stakeholder Advisory Board, and crop- and region-specific grower influencer teams.

Goals / Objectives
The overarching goal of this proposal is to develop and deliver systems-based integrated management programs to berry and cherry growers that are cost-effective and environmentally-sustainable for long-term management of SWD in the U.S. We will achieve this goal through the following objectives: 1) Implementation of best management programs (BMPs) for sustainable management of SWD in collaboration with grower influencers;2)Develop economics-based decision aid tools to increase profitability; 3) Evaluate sustainable alternatives to insecticides for long-term SWD management;4) Assess and reduce the risk of insecticide resistance development; and 5)Develop and disseminate actionable recommendations that enable producers to optimize pest management decisions, and evaluate their impact.

Project Methods
Objective 1. Implementation of best management programs (BMPs) for sustainable management of SWD in collaboration with grower influencers:Project leaders (PDs/PIs) in each state and region have will work in collaboration with "Grower Influencers" to implement best management programs for sustainable management of SWD.Objective 2.Develop economics-based decision aid tools to support the identification and implementation of profit-maximizing SWD management strategies.(2.1) Assess short- and long-term economic impacts of conventional SWD control strategies:We will select 6-8 areas of focus to develop SWD economic assessments of prevailing conventional control strategies based on sprays. For each area of focus, we will collect detailed data to 1) develop partial crop budgets to establish baseline profit figures (i.e., profits for a farm free of SWD infestation); 2) estimate the costs and benefits of both conventional and sustainable alternative control strategies, and 3) assess economic losses due to SWD.(2.2) Develop economic decision-aid tools to help growers make optimal SWD control decisions:The development of the economic decision-aid tool will be based on the data collected from Obj. 2.1. The tool will be Excel-based (a tool commonly employed by growers and extension educators), interactive, and the context will be tailored to region and crop-specific management comparison and concerns.The tools will reflect the budgets to simulate the profit implications of SWD management, accounting for production and economic risks.Objective 3. Evaluate sustainable alternatives to insecticides for long-term SWD management.(3.1) Improve biological control using native and exotic natural enemies:Develop Regional Insectaries and Improve Rearing Programs.To facilitate parasitoid release, regional insectaries will be established with different state agencies (e.g., California Dept. of Food and Agriculture, Michigan Dept. of Agriculture and Rural Development) for mass-rearing of bothG. brasiliensisand the resident pupal parasitoids. Studies will also be conducted to improve rearing and release methodologies.Release Exotic Parasitoid.Our primary goal is to releaseG. brasiliensisand intensively monitor those sites to determine establishment, effectiveness, and spread of this exotic larval parasitoid. Releases will be conducted regionally (CA, GA, MI, OR, WA), and in a variety of different orchards and unmanaged habitats. For open field releases, we will use methodologies similar to those used to establish parasitoids of the olive fruit fly (Wang et al. 2011, Daane et al. 2015).Additionally, regional cage-studies will be conducted to gain a better understanding of biotic and abiotic parameters that may affect field parasitism rates in order to optimize parasitoid establishment (after Wang et al. 2011).Release of Endemic Pupal Parasitoids (ifG. brasiliensis is not permitted for release).Adults and parasitized pupae ofP. vindemiaeand/orT. drosophilaewill be released in netted crop systems, organic systems, and non-crop systems adjacent to susceptible crops. Parasitoid impact will be monitored using sentinel traps and collection of infested fruit.(3.2) Develop economically-viable behavioral management tools.Optimize and implement behavior-based strategies to manage SWD. The goal of these experiments is to evaluate attract-and-kill strategies to reduce insecticide applications. We will compare the efficacy of various attract-and-kill strategies including the SWD HOOK® formulation and a food-grade gum in field and semi-field experiments. In addition, semi-field experiment will be conducted to optimize these attract-and-kill strategies alone and in combination in NJ, OR, GA, and NY.Discover and test novel and existing repellents and oviposition-deterrents for SWD. We plan to identify and evaluate repellents and oviposition-deterrents from various sources (e.g., octenol (Wallingford et al. 2016),Botrytisvolatiles (Cha et al. 2019), and essential oils (Renkema et al. 2016) for the development of push-pull strategies in NJ, NY, OR, and GA. Finally, in years 3 & 4, we will evaluate the combination of repellents/deterrents at the most efficient concentration, with an attract-and-kill strategy in a push-pull strategy under (small-plot) field (blueberry and raspberry) conditions in NJ, NY, OR, GA, CA, and ME.OBJECTIVE 4. Assess and reduce the risk of insecticide resistance development.(4.1) Monitor development and extent of insecticide resistance:We will establish regional hubs in Western, Central, and Eastern U.S. (California, Oregon Michigan, and Georgia) for resistance monitoring to annually assess SWD susceptibility, especially in areas where control failures have been reported. Team members and other extension colleagues across the country will collect SWD from field sites across the country at the end of crop harvest, and assess susceptibility to commonly used insecticides using the rapid assessment bioassay developed by our team (Van Timmeren et al. 2019).(4.2) Determine mechanisms of insecticide resistance:We will establish confirmed field-resistant SWD isogenic strains in the lab to determine resistance mechanisms using high-throughput sequencing approaches. Transcriptome sequencing as described in Mishra et al. (2017) will be effective in determining molecular mechanisms underlying target site and metabolic resistance.Afterthe identification of specific mutations that may confer insecticide resistance, we propose to engineer the homologous mutations in the closely relatedDrosophila melanogasterby leveraging molecular genetics approaches. We can then subject these transgenic fly lines to insecticide bioassays and confirm that specific mutations indeed confer insecticide resistance.(4.3) Examine fitness costs of insecticide resistance to inform resistance management:Potential fitness costs of field-resistant SWD strains will be investigated as described in Cao et al. (2014) andGuillem-Amar et al. (2020)to determine if they may counteract selection and ultimately impact expression of resistance within local populations, or spread of resistance to new regions.Objective 5.Develop and disseminate actionable recommendations that enable producers to optimize pest management decisions, and evaluate their impact.(5.1) Develop and disseminate actionable IPM recommendations to stakeholders (Extension & outreach):We have developed a comprehensive outreach program to ensure effective and timely dissemination and implementation of information generated in this project. We have a diverse outreach plan that includes partnership with Southern IPM Center to provide technological assistance to widely disseminating information generated in this project. Our outreach plan will be primarily achieved by on-farm demonstrations in collaboration withGrower Influencers, grower meetings, on-farm field days, and Extension Bulletins and Circulars. We will also disseminate the results from this project through technology-driven online resources including our project website (https://swdmanagement.org/), via regional and commodity-based email listservs, eNewsletters, blogs, social media, and webinars.(5.2) Evaluate the impact of this project on SWD management and grower profitability:Systematic monitoring and evaluation are an integral part of this project to capture social and biological impacts of the project. The evaluation will be led by evaluation specialists from the Impact Evaluation Unit at the University of Georgia. Monitoring of project activities will start at the beginning of the project for program improvement (formative) and continue through the life of the five-year project for accountability (summative) purposes following best practices in evaluation methods.

Outputs
Target Audience:Target audience for this project included small fruit growers, small fruit processors and marketers, pest management consultants, research and extension personnel, as well as private industry personnel. Our project team reached out to those target audience through research and extension presentations, extension publications, online resources, blog posts, field days, as well as one-on-one meetings throughout the United States. Changes/Problems: Nothing Reported What opportunities for training and professional development has the project provided?During Year 4, this project provided multiple training and professional development opportunities for 7 post-docs, 11 research technicians, 5 graduate students, and 7 undergraduate students who were supported full- or part-time through this project. Additionally, most of the labs involved in this project worked in collaboration with local Extension personnel and Pest Management Consultants and trained those individuals specifically on identification, monitoring, and management of SWD. How have the results been disseminated to communities of interest?The results were disseminated to growers and other stakeholders through numerous research and extension presentations, publications, project webinar, blog posts, web articles, field days and one-on-one meetings with growers. Please see products section for detailed listing of the activities and outputs of this project. What do you plan to do during the next reporting period to accomplish the goals?For the next year, we got no-cost extension for this project to complete ongoing field and lab studies under each objective, analyze data, and develop research and extension publications to further disseminate findings of this project. Final report for this project will be submitted at the end of no-cost extension period next year.

Impacts
What was accomplished under these goals? Spotted-wing drosophila (SWD) was first detected in California in 2008 and since then has become established throughout the United States asthe most economically significant and persistent pest of small fruits including blueberries, blackberries, raspberries, strawberries, and cherries, with annual value of over $5.8 billion (USDA NASS 2018). Crop losses due to SWD in the United States have been estimated to exceed $718 million annually. To meet zero tolerance thresholds by marketers and consumers, fruit growers have been in crisis mode using calendar-based spray programs to control SWD which are both economically and environmentally unsustainable.The long-term goal of this project is to develop and deliver systems-based integrated pest management programs to berry and cherry growers that are cost-effective and environmentally sustainable for long-term management of SWD in the U.S.The leading researchers from 11 major land-grant universities and USDA-ARS are involved in this multistate project. The team members met with the advisory board virtually via zoom on February 12-13, 2024 to get their feedback and finalize plans for Year 4. Annual project webinar was delivered on December 4, 2023 which was attended by over 350 stakeholders live and the recording has since been watched 272 times online. During this reporting period we were able to accomplish the proposed projects. Crop and region-specific monitoring and management strategies were implemented at commercial farms. Developed economic decision tools for farmers to determine economic benefits of fruit sampling for SWD infestation and postharvest cooling. Oviposition deterrent and other behavioral control technologies including Combi-protec were evaluated to develop attract-and-kill strategies. Laboratory colonies of exotic parasitoid Ganaspis kimorus (= brasiliensis) were established in all participating states and parasitoids were released in participating states. Some states successfully re-captured parasitoids in post-release sampling indicating that the exotic parasitoids may have survived and established at release sites. High level of insecticide resistance to spinosad, malathion and zeta-cypermethrin was detected in SWD populations in CA and further genetic analysis is underway to determine mechanisms. Stakeholder surveys conducted by evaluation team indicated that implementation of all research and extension activitieswas highly successful, and the achievements were beyond the promised deliverables through synergistic collaborations that resulted in creative and leading-edge innovations to mitigate SWD. During Year 4 of this project, the proposed field and laboratory studies were implemented in participating states and here are the specificaccomplishments: Objective 1:Based on stakeholder feedback, studies were conducted in all participating states. During the field season, on-farm research for Objective 1 related activities were conducted at multiple farms across six states including NC, GA, MI, OR, ME, and NY. Research studies evaluated new dry trapping methods, developed an easy method to detect SWD in fruit, and evaluated efficacy of perimeter only sprays to control SWD. To minimize insecticide sprays, we developed decision tree-aided management plan and conducting a pilot study to evaluate male counts in red panel taps and fruit sampling as predictors of SWD infestation levels, and triggers to implement SWD management programs in the field. Abundance of non-target species in fruit crops was also assessed to determine non-target impacts of SWD management. Objective 2:The economists analyzed cost of multiple SWD monitoring and management strategies evaluated in field trials to develop crop budgets and conducted cost-benefit analysis on various SWD management strategies to determine profitability for growers. A grower panel was conducted to determine their choice of SWD management strategies and growers preferred non-chemical strategies over use of insecticides to control SWD and indicated their willingness to pay additional cost for non-chemical control methods. As a result, crop-specific integrated SWD management strategies were developed and shared with growers to maximize profitability. Objective 3: Behavioral control studies focused on evaluating attract and kill method using Combi-protec with and without insecticides. When combined with Combi-protec, half rate of some insecticides was just as effective as full rate. A new product 2PF was also evaluated in a push-pull system to control SWD. As a result of these methods, insecticide residues were decreased by 90% and control costs decreased by 40%. The biological control studies focused on releasing and recapturing of exotic parasitoids in the field and evaluating efficacy of both Ganaspis kimorum and Leptopilina japonica to control SWD. Other studies focused on evaluating compatibility of these parasitoids with commonly used chemical and biological insecticides. Objective 4: SWD field populations were collected from several sites in berry and cherry producing regions in CA, WA, NC, MI, and GA and screened for insecticide resistance. Highly levels of insecticide resistance to spinosad, malathion and zeta-cypermethrin was detected in SWD populations in CA. Analysis of resistance mechanisms showed evidencemetabolic resistance for populations resistant to pyrethroids, and evidence of penetration resistance and metabolic resistance for populations resistant to spinosads.Further lab studies showed that resistance was stable in the absence of migration of susceptible individuals. However, resistance quickly declines when resistant flies were mixed with susceptible flies. Objective 5: Evaluation team conducted national stakeholder surveys and concluded that the overall implementation of the research activities of the SCRI research team according to the project narrative submitted to USDA was highly successful and the achievements were beyond the promised deliverables through synergistic collaborations that resulted in creative and leading-edge innovations to mitigate SWD.

Outputs
Target Audience:Target audience for this project included small fruit growers, small fruit packers, processors and marketers, pest management consultants, research and extension personnel, as well as private industry personnel. Our project team reached out to those target audience through research and extension presentations, extension publications, online resources, blog posts, field days, as well as one-on-one meetings throughout the United States. Changes/Problems: Nothing Reported What opportunities for training and professional development has the project provided?DuringYear3,thisprojectprovidedmultipletrainingandprofessionaldevelopmentopportunitiesfor6post-docs,12 research technicians,5graduatestudents,and6undergraduatestudentswhoweresupportedfull-orpart-timethroughthisproject.Additionally,mostofthelabsinvolvedinthisprojectworkedincollaborationwithlocalExtensionpersonnel and PestManagementConsultantsandtrainedthoseindividualsspecificallyonidentification,monitoring,andmanagementof SWD. How have the results been disseminated to communities of interest?Theresultsweredisseminatedtogrowersandotherstakeholdersthroughnumerousresearchandextensionpresentations, publications,blog posts,web articles, fielddaysandone-on-onemeetingswithgrowers.Please see products section for details. What do you plan to do during the next reporting period to accomplish the goals?DuringtheYear 4,we will continue to work with growers to implement and evaluate improved region- and crop- specific IPM programs, conduct field and semi-field studies to evaluate novel technologies, and disseminate our findings to growers and other stakeholders.

Impacts
What was accomplished under these goals? Spotted-wing drosophila (SWD) was first detected in California in 2008 and since then has become established throughout the United States asthe most economically significant and persistent pest of small fruits including blueberries, blackberries, raspberries, strawberries, and cherries, with annual value of over $5.8 billion (USDA NASS 2018). Crop losses due to SWD in the United States have been estimated to exceed $718 million annually. To meet zero tolerance thresholds by marketers and consumers, fruit growers have been in crisis mode using calendar-based spray programs to control SWD which are both economically and environmentally unsustainable.The long-term goal of this project is to develop and deliver systems-based integrated pest management programs to berry and cherry growers that are cost-effective and environmentally sustainable for long-term management of SWD in the U.S.The leading researchers from 11 major land-grant universities and USDA-ARS are involved in this multistate project. The team members met with the advisory board virtually via zoom on February 22-23, 2023 to get their feedback and finalize plans for Year 3. Annual project webinar was delivered on December 8, 2022 which was attended by over 300 stakeholders live and the recording has since been watched numerous times online. During this reporting period we were able to accomplish the proposed projects. Crop and region-specific monitoring and management strategies were implemented at commercial farms. Developed economic decision tools for farmers to determine economic benefits of fruit sampling for SWD infestation and postharvest cooling. Oviposition deterrent and other behavioral control technologies including Combi-protec were evaluated to develop attract-and-kill strategies. Laboratory colonies of exotic parasitoid Ganaspis brasiliensis were established in all participating states and initial releases were made in several states. Some states successfully re-captured parasitoids in post-release sampling indicating that the exotic parasitoids may have survived and established at release sites. High level of insecticide resistance to spinosad, malathion and zeta-cypermethrin was detected in SWD populations in CA and further genetic analysis is underway to determine mechanisms. Stakeholder surveys conducted by evaluation team indicated that implementation of all research and extension activitieswas highly successful and the achievements were beyond the promised deliverables through synergistic collaborations that resulted in creative and leading-edge innovations to mitigate SWD. During Year 3 of this project, the proposed field and laboratory studies were implemented in participating states and here are the specificaccomplishments: Objective 1: Based on stakeholder feedback, studies were conducted in all participating states. During the field season, on-farm research for Objective 1 related activities was conducted at multiple farms across six states including NC, GA, MI, OR, ME, and NY. Research objectives included developing decision tree management aid and conducting a pilot study to evaluate male counts in red panel taps and fruit sampling as predictors of SWD infestation levels, and triggers to implement SWD management programs in the field. Other studies detected multiple bee species nesting in commercial blackberry fields and a time series was conducted to document establishment across the field season. Objective 2:The economic analysis and a research paper comparing adult trapping and fruit sampling in Oregon state was published. Results show thatcontrol strategies that incorporate fruit sampling exhibit higher average profits than calendar-based spraying control strategies in our baseline scenario for organic blueberry production in Oregon. Data were alsocollected on exclusion netting at "The Berry Patch" farm in Upstate New York State to conduct a cost-benefit analysis of using exclusion netting as a strategy to control for SWD. A consumer survey to assess impact of IPM methods and food safety measures on fresh blueberries and cherry consumption. Objective 3: On-farm trials were conducted to evaluate efficacy of a standard insecticide program with and without Combi-protec. The initial results look promising. In some trials reduced insecticide rate when applied with Combi-protec provided just as good a control of SWD as full insecticide rate. Laboratory colonies of exotic parasitoid Ganaspis brasiliensis were established in all participating states. Most states have started releasing these exotic parasitoids at commercial farms. Some states successfully re-captured parasitoids in post-release sampling indicating that the exotic parasitoids may have survived and established at release sites. Objective 4: Highly levels of insecticide resistance to spinosad, malathion and zeta-cypermethrin was detected in SWD populations in CA. Analysis of resistance mechanisms showed evidencemetabolic resistance for populations resistant to pyrethroids, and evidence of penetration resistance and metabolic resistance for populations resistant to spinosads.Further lab studies showed that resistance was stable in the absence of migration of susceptible individuals. However, resistance quickly declines when resistant flies were mixed with susceptible flies. Objective 5: Based on the stakeholder surveys,evaluation team concluded that the overall implementation of the research activities of the SCRI research team according to the project narrative submitted to USDA was highly successful and the achievements were beyond the promised deliverables through synergistic collaborations that resulted in creative and leading-edge innovations to mitigate SWD.

How have the results been disseminated to communities of interest?Theresultsweredisseminatedtogrowersandotherstakeholdersthroughnumerousresearchandextensionpresentations,publications,blog posts,web articles, fielddaysandone-on-onemeetingswithgrowers.Please see products section for details. What do you plan to do during the next reporting period to accomplish the goals?DuringtheYear 3,we will continue to work with growers to implement and evaluate improved region- and crop- specific IPM programs, conduct field and semi-field studies to evaluate novel technologies, and disseminate our findings to growers and other stakeholders.

Impacts
What was accomplished under these goals? Spotted-wing drosophila (SWD) was first detected in California in 2008 and since then has become established throughout the United States asthe most economically significant and persistent pest of small fruits including blueberries, blackberries, raspberries, strawberries, and cherries, with annual value of over $5.8 billion (USDA NASS 2018). Crop losses due to SWD in the United States have been estimated to exceed $718 million annually. To meet zero tolerance thresholds by marketers and consumers, fruit growers have been in crisis mode using calendar-based spray programs to control SWD which are both economically and environmentally unsustainable.The long-term goal of this project is to develop and deliver systems-based integrated management programs to berry and cherry growers that are cost-effective and environmentally sustainable for long-term management of SWD in the U.S.The leading researchers from 11 major land-grant universities and USDA-ARS are involved in this multistate project. The team members met with the advisory board virtually via zoom on February 9-10, 2022 to get their feedback and finalize plans for Year 2. During this reporting period we were able to accomplish the proposed projects. Crop and region-specific monitoring and management strategies were implemented at commercial farms. Developed interactive economic decision tools for farmers to determine economic benefits of fruit sampling for SWD infestation and postharvest cooling. Oviposition deterrent and other behavioral control technologies including Combi-protec were evaluated to develop attract-and-kill strategies. After getting APHIS permits, laboratory colonies were established in all participating states and initial releases were made in several states, sampling is underway to determine recovery and establishment of exotic parasitoids. Highly levels of insecticide resistance to spinosad, malathion and zeta-cypermethrin was detected in SWD populations in CA and further genetic analysis is underway to determine mechanisms. Evaluation team conducted formative evaluation of the project to establish baselines and interviewed many growers and researchers and determined that the project has been successfully implemented. During Year 2 of this project, the proposed field and laboratory studies were implemented in participating states and here are the specificaccomplishments: Objective 1: All states met with their respective task force growers in early winter/early spring to discuss findings and plan upcoming projects. During the field season, on-farm research for Objective 1 related activities was conducted across 6 states at a total of at least 25 farms. Research objectives included comparing data from fruit sampling to data collected from various monitoring trap methods. Objective 2:We developed an interactive economic decision tool for cold storage investment analysis on SWD control strategies used for blueberries in North Carolina, and it has been published in the NC extension website. The economic analysis and a research paper draft for comparing adult trapping and fruit sampling in Oregon state will be finished soon. We have collected data on different chemical application needs according to different SWD pressures in sweet cherries in WA state. We will use these data to determine the potential efficacy of using Extenday to control SWD. Objective 3: Field trials were conducted to evaluate efficacy of repellent 2pf and attractant Combi-protec with full and half-rate of insecticides. The initial results look promising, and the data are currently being analyzed. Findings will be shared with the growers as soon as they ready. After getting APHIS permits, laboratory colonies of the most important exotic larval parasitoid of SWD,Ganaspis brasiliensis,were established in all participating states and initial releases were made this year in several states, sampling is underway to determine recovery and establishment of exotic parasitoids. Objective 4: Highly levels of insecticide resistance to spinosad, malathion and zeta-cypermethrin was detected in SWD populations in CA and further genetic analysis is underway to determine mechanisms and fitness costs associated with resistance. Field populations screenings in other states didn't detect significant resistance in their SWD field populations. Objective 5: Evaluation team conducted formative evaluation of the project to establish baselines. The evaluation team found that the SCRI team was operating in full performance mode (Bonebright, 2010; Largent, 2016), which was favorable to the achievement of project objectives. We found that major research decisions were taken with implementing novel research protocols, monthly team and sub-team meetings to develop protocols for delivering research results to growers, implementing new ideas for the emergence of team engagement in multi-site experimentation, and prolific publication of research results.

Outputs
Target Audience:Traget audience for this project included small fruit growers, small fruit processors and marketers, pestmanagement consultants, research and extension personnel, as well as private industry personnel. Our project team reached out to those target audiencethrough research andextension presentations, extension publications, online resources, blog posts, field days, as well as one-on-one meetingsthroughout the United States. Changes/Problems: Nothing Reported What opportunities for training and professional development has the project provided?DuringYear1,thisprojectprovidedmultipletrainingandprofessionaldevelopmentopportunitiesfor7post-docs,8research technicians,6graduatestudents,and8undergraduatestudentswhoweresupportedfull-orpart-timethroughthisproject.Additionally,mostofthelabsinvolvedinthisprojectworkedincollaborationwithlocalExtensionpersonnelandPestManagementConsultantandtrainedthoseindividualsspecificallyonidentification,monitoring,andmanagementofSWD.

What do you plan to do during the next reporting period to accomplish the goals?DuringtheYear 2,we will continue to work with growers to implement and evaluate improved region- and crop- specific IPM programs, conduct field and semi-field studies to evaluate novel technologies, and disseminate our findings to growers and other stakeholders.?

Impacts
What was accomplished under these goals? Since it was first detected in California in 2008, spotted-wing drosophila (SWD) has become established throughout the United States asthe most economically significant and persistent pest of blueberries, blackberries, raspberries, strawberries, and cherries, which have a combined value of more than $5.8 billion annually (USDA NASS 2018). Crop losses due to SWD in the United States have been estimated to exceed $718 million annually. To meet zero tolerance thresholds by marketers and consumers, fruit growers have been in crisis mode using calendar-based spray programs to control SWD which are both economically and environmentally unsustainable.The long-term goal of this project is to develop and deliver systems-based integrated management programs to berry and cherry growers that are cost-effective and environmentally sustainable for long-term management of SWD in the U.S.The leading researchers from 11 major land-grant universities and USDA-ARS are involved in this multistate project. The team members met with the advisory board virtually via zoom on March 1-2, 2021 to get their feedback and finalize plans for Year 1. Our research plans for Year 1 (2020-2021) were significantly affected by COVID-19 pandemic. However, we were able to accomplish most of the proposed projects this year. Crop and region-specific monitoring and management strategies were implemented at commercial farms. Developed economic decision aid tools for farmers to determine economic benefits of fruit sampling for SWD infestation and postharvest cooling. Oviposition deterrent and other behavioral control technologies were evaluated to develop attract-and-kill strategies. We successfully obtained APHIS permits to release exotic parasitoid to enhance SWD biocontrol in the field in participating states. Laboratory colonies are currently being prepared in quarantine labs for distribution and field releases. Highly levels of insecticide resistance to spinosad, malathion and zeta-cypermethrin was detected in SWD populations in CA and further genetic analysis is underway to determine mechanisms. Evaluation team conducted formative evaluation of the project to establish baselines and determined that the project has been successfully implemented in its first year of operation (2020-2021). During Year 1 of this project, all participating labs had planned to conduct on-farm research projects to achieve the objectives. However, our studies were significantly affected by COVID-19 pandemic due to varying levels of restrictions on field research in various states and here are the specificaccomplishments: Objective 1: Grower influencer teams were established in participating states and researchers in some states were able to implement region- and crop-specific monitoring and management strategies at commercial farms. Follow up meetings with grower influencers will be conducted to get their feedback to evaluate the implemented programs and improve them for the next year. Objective 2: We focus on the economics of SWD monitoring and fruit sampling to identify optimal control strategies that minimize insecticide applications for different region and crop combinations. This will allow us to develop economics-based decision aid tools to increase profitability. We documented the buyer's testing behavior of SWD for North Carolina blueberry production. We also developed a model to examine the economics of SWD sampling. This model addresses the following question: what type of sampling strategy maximizes grower profits in the presence of SWD infestations? An initial model is currently being calibrated to Oregon blueberries. We are currently developing an economic-based decision aid tool for Oregon blueberries. Objective 3: Large-scale trials with Food Grade Gum in Western production regions resulted in ~50% reduction in damage by SWD when compared to Untreated Control, or Grower standard compared to Grower Standard + Control.Food Grade Gum can therefore be used as a synergist with conventional control to manage damage by SWD. Areawide sampling resulted in significant savings with collaborator grower.Sampling of eggs resulted in ~10 day early warning compared to fruit sampling only. Novel behavioral control technologies including attractants (ACTTRA and Combi-Protec) and repellents (2pf) were evaluated to develop attract-and-kill or push-pull strategies. Initial data look promising and further field trials will be conducted next year to determine efficacy in field settings. One most important exotic larval parasitoidGanaspis brasiliensisofDrosophila suzukiihas been finally approved for field release in the US. We have developed rearing protocols for this parasitoid. We have also imported another strain of this parasitoid (originally from Japan) and developed similar rearing protocols for the new strain Objective 4: Highly levels of insecticide resistance to spinosad, malathion and zeta-cypermethrin was detected in SWD populations in CA and further genetic analysis is underway to determine mechanisms and fitness costs associated with resistance. Field populations screenings in other states didn't detect significant resistance in their SWD field populations. Objective 5: Evaluation team conducted formative evaluation of the project to establish baselines. The evaluation team found that the SCRI team was operating in full performance mode (Bonebright, 2010; Largent, 2016), which was favorable to the achievement of project objectives. We found that major research decisions were taken with implementing novel research protocols, monthly team and sub-team meetings to develop protocols for delivering research results to growers, implementing new ideas for the emergence of team engagement in multi-site experimentation, and prolific publication of research results.
