What opportunities for training and professional development has the project provided? This project has provided training on molecular methods, field biology, and behavior of BMSB to undergraduates. Additionally, a postdoctoral researcher is coordinating a regional investigation on the use of border sprays for BMSB management in peach and apple. How have the results been disseminated to communities of interest? Drs. Nielsen and Hamilton disseminated research findings through grower meetings, extension meetings, and research meetings. Dr. Nielsen shared knowledge on biology and management with concerned stakeholders, industry, and federal groups in New Zealand as they prepare biosecurity protocols to prevent and/or stop the invasion of BMSB with a specific focus on eDNA for biosurveillance. At the regional level, Dr. Nielsen presented methods to integrate BMSB management while protecting pollinators and natural enemies to 100+ growers with management updates through annual meetings and twilight talks. The Rutgers Fruit Production Guide was updated for BMSB management recommendations and is available in print and online. The Nielsen lab's research was highlighted in popular press specifically on the findings and dispersal behavior of T. japonicus. What do you plan to do during the next reporting period to accomplish the goals?
Nothing Reported
Impacts What was accomplished under these goals?
Through this research, our group identified the egg parasitoid of Brown Marmorated Stink Bug (BMSB) (its primary biological control agent) at two commercial farms. Evaluated population pressure of BMSBin 1 km2 farms and surveyed for natural enemies. We investigated the habitat preference and foraging ecology of the egg parasitoid (Trissolcus japonicus) in peaches and soybean. We found that T. japonicus will readily disperse into peaches which provides promise for biological control in agricultural systems. There was refinementof BMSB monitoring methods using different aggregration pheromone lures. This research will contribute to establishing a trap-based tool for making management decisions. Also, we conducted an evaluation of border-sprays as a management tool in commercial peaches at 5, 10 and 20-acre size plots. In 2018 all plot sizes were not significantly different than full block insecticide applications in 5-acre blocks in terms of stink bug injury at harvest.Refinementof management recommendations for fruit growers. Research findings on the biology and behavior of BMSB are integrated into management tactics and recommendations for tree fruit and may also benefit homeowners.

What opportunities for training and professional development has the project provided?This project has provided training on molecular methods, field biology, and behavior of BMSB to undergraduates. Additionally, a postdoctoral researcher is coordinating a regional investigation on the use of border sprays for BMSB management in peach and apple. How have the results been disseminated to communities of interest?Drs. Nielsen and Hamilton disseminated research findings through grower meetings, extension meetings, and research meetings. As part of a national collaborative effort, the StopBMSB.org website published three electronic fact sheets on BMSB biology and management in orchards and vineyard crops, available in English and Spanish. Dr. Nielsen shared knowledge on biology and management with concerned stakeholders, industry, and federal groups in New Zealand as they prepare biosecurity protocols to prevent and/or stop the invasion of BMSB. Dr. Nielsen also shred similar information with 90+ apple growers in Michigan at a daylong workshop. At the regional level, Dr. Nielsen presented methods to integrate BMSB management while protecting pollinators and natural enemies to 200+ growers at the Mid-Atlantic Fruit and Vegetable Convention. Within NJ, we provided 100+ growers with management updates through annual meetings and twilight talks. The Rutgers Fruit Production Guide was updated for BMSB management recommendations and is available in print and online. The Nielsen lab published a blog post on the important finding of the parasitoid Trissolcus japonicus which was picked up by the trade magazine Growing Produce. What do you plan to do during the next reporting period to accomplish the goals?We will finalize the gut content analysis to detect predation of BMSB in the field. We will refine placement of baited traps for management decisions and refine timing of applications incorporating a phenological based degree-day model and incidence sampling through pheromone traps. We will investigate the distribution and ecology of Trissolucs japinoicus in peaches. We will conduct on-farm trials (year 2) investigating border sprays in peaches at scale of up to 20 acres. We will analyze a 10 year dataset on BMSB populations as measured through black light traps throughout NJ and identify abiotic parameters that influence population dynamics and densities.
Impacts What was accomplished under these goals?
This year, Nielsen and Hamilton deployed yellow sticky cards and over 435 sentinel BMSB egg masses as part of a state-wide survey for the egg parasitoid Trissolcus japonicus. This is the primary parasitoid species of BMSB in Asia and is responsible for maintaining populations below economic injury levels. A taxonomist is identifying Specimens found on the yellow sticky cards but 3 egg parasitized masses were identified in peaches indicating that T. japonicus can attack BMSB eggs within agricultural production systems. Significant progress has been made in using molecular markers (qPCR) to identify key predators of BMSB in the field. To date we have tested 400+ predators, of which 14% tested positive for BMSB DNA indicating that they had consumed BMSB within the last 48-72h. Key predatory taxa identified were damsel bugs, katydids, earwigs, and assassin bugs. Ants and spider specimens will be analyzed in 2018. This matches with the laboratory work on stage-specific predation that found that the key generalist predators identified (katydids, damsel bugs, assassin bugs, lady beetles) preferred to feed on different life stages of BMSB (egg, 1st instar, 2nd instar nymphs) and that previous estimates using sentinel egg masses underestimated predation. We compared the population response of BMSB to two commercially available pheromone lures relative to the populations within the peach tree and injury. This information will provide the basis for trap-based monitoring programs for BMSB, a critical part of IPM programs. We identified that the high release rate lure sampled from a larger area than was resident within the peach orchard, perhaps inflating perceived pest densities. A slow release rate lure best represented local population densities and did not inflate injury. To complement these findings, we investigated the spillover distance of the aggregation pheromone lure when placed in peaches. We found that injury spillover occurs to at minimum the adjacent trees. At four commercial apple orchards, we evaluated the application of insecticide to only orchard borders for management of BMSB. We found that damage was equal or less relative to that of grower's standard practices, despite not treating the interior of the orchard. This approach reduces the amount of insecticide applied and benefits beneficial insects such as predators and bees. At 5 commercial peach orchards we investigate the use of border sprays to manage BMSB and reintroduced mating disruption for internal worms and managed flowering weeds within the row middles to reduce foraging pollinators within the orchard post-bloom. We found equal or less stink bug injury at harvest for growers using border sprays to manage BMSB relative to their standard management. Border sprays have the potential to reduce insecticide sprays 25-50% over the standard. Unfortunately, no impact was seen on the beneficial insect community after 1 year. Natural enemy populations did not differ between the two management tactics, however the parasitized eggs with T. japonicus were only within the border spray plots. Pollinators sampling was done with blue vane traps at 3 time periods post bloom. We have identified over 800 bee specimens to genus. There was no impact on diversity or abundance between plots with and without flowering weeds. Bees will be identified to species to determine if diversity indices differ at a higher taxonomic level. We expect that beneficial insects will benefit long-term from this strategy. In 2017, we collected host plant volatiles during different growth of apple and peach to identify key olfactory cues responsible for dispersal or host plant selection. In previous research, nymphs had demonstrated attraction to volatiles produced during fruiting, although with less attractive hosts.

Outputs Target Audience: Specialty crop producers in the mid-Atlantic states are the primary targets of this research. Research findings on the biology and behavior of BMSB also impact management in field crops and homeowners. Efforts of this project include newsletter articles, on-farm research with collaborating growers and extension meetings. Changes/Problems:

What opportunities for training and professional development has the project provided?This project has provided training on molecular methods on field biology and behavior of BMSB to undergraduates. Additionally, a postdoctoral researcher has been trained on some of these objectives. How have the results been disseminated to communities of interest?Results have been disseminated through grower meetings, extension meetings,and research meetings. Two electronic fact sheets on BMSB biology and management in orchards and vineyard crops were developed in English and Spanish. What do you plan to do during the next reporting period to accomplish the goals?We will finalize the gut content analysis to detect predation of BMSB in the field. We will compare aggregation pheromone lures for trap-based decision management. We will survey for the egg parasitoid Trissolcus japonicus. We will investigate border sprays in peaches at scale of up to 20 acres.
Impacts What was accomplished under these goals?
A survey was conducted in untreated peaches and the adjoining woods for the egg parasitoid Trissolcus japonicus. No parasitism was found and predation was recorded as low. Significant progress was made in using molecular markers (qPCR) to identify key predators of BMSB in the field. To date we have tested 400+ predators, of which 15% tested positive for BMSB DNA indicating that they had consumed BMSB within the last 48-72h. This matches with the laboratory work on stage-specific predation that was conducted which found that thekey generalist predators identified (katydids, damsel bugs, assassin bugs, lady beetles) preferred to feed on different life stages of BMSB (egg, 1st instar, 2nd instar nymphs) and that previous estimates using sentinel egg masses underestimated predation. A stage-specific predictive model was developed for BMSB at 8 geographic locations in the US. It predictedtwo generations per year in all locations however, due to abiotic conditions, population sizes were significantly different across locations. This suggests that the range will not be throughout the entire US but that it could still have significant impacts in critical agricultural areas. Rutgers utilized a state-wide system of blacklight traps to monitor BMSB on vegetable and fruit farms. Populations were higher this year than in previous years, but still lower than the "outbreak" years of 2009-2011. We compared the population response of BMSB to two commercially available pheromone lures relative to the populations within the peach tree and injury. This information will provide the basis for trap-based monitoring programs for BMSB, a critical part of IPM programs. We identified that the high release rate lure sampled from a larger area than was resident within the peach orchard, perhaps inflating perceived pest densities. A slow release rate lure best represented local population densities and did not inflate injury. At four commercial apple orchards we evaluated the application of insecticide to only orchard borders for management of BMSB. We found that damage was equal or less relative to that of grower's standard practices, despite not treating the interior of the orchard. This approach reduces the amount of insecticide applied and benefits beneficial insects such as predators and bees. Host plant volatiles were collected during different growth stages of corn, soybean, pepper, and swiss chard. In previous research, nymphs had demonstrated attraction to these plants at the growth stage where they were producing fruit. In the greenhouse, blends of five host plant volatiles that were most attractive were compared to a control. There was a significant negative dose response suggesting that the higher concentrations were repellant. These same blends were evaluated in a mark-release-recapture scenario in the field but were not found to be more attractive than the control at 5m distances.

Progress 10/01/14 to 09/30/15
Outputs Target Audience:Sepcialty crop producers in the mid-Atlantic states, primarily pepper, apple, peach and blueberry growers, are the primary targets of this research. However, research findings on thebiology and behavior of BMSB also impact management in field crops and homeowners. Efforts of this project include newsletter articles, on-farm research with collaborating growers and extension meetings. Changes/Problems:A significant change in this research is that small fruit, specifically blueberry, will not be included going forward due to changes in the pest complex and grower priorities. What opportunities for training and professional development has the project provided?This project has provided funding to partially support 2 PhD students in the department of entomology and a post-doctoral resesarcher. Research related to this project has also provided training opporutnities for 3 undergraduate students throughout New Jersey. How have the results been disseminated to communities of interest?Science-based materials have been disseminate through collaboration with NJ growers through on-farm evaluation and demonstration trials. Growers have also permitted access to their land and crops for additional surveys. A factsheet on IPM-CPR, an approach utilizing border sprays in peaches for BMSB management, was published on the NE SARE website.Participating growers will continue in 2016 indicating a high level of satisfaction with the project. What do you plan to do during the next reporting period to accomplish the goals?Research will continue on the identification and impact of natural enemies for BMSB. The dispersal behavior of adults is also being investigated in peach orchards. Host plant characterstics, specifically chemical odor cues, are being explored for behavioral response by BMSB. Monitoring methods, particularily in peach, are being investigated to relate catches in trap to population estimates and injury within a tree to develop decision tools.
Impacts What was accomplished under these goals?
1)Assess the extent and nature of injury caused brown marmorated stink bug: Patterns of injury within field and the diel activity were studied. It was identified that BMSB nymphs are primarily active at nightand that adults are equally active throughout the day. (2)Determine the potential for biological control of the brown marmorated stink bug: Laboratory bioassays were conducted to identify feeding preferences of generalist predators. Specifically, we identified that predators showed preference for BMSB lifes tages. For example, katydids preferred to feed upon eggs while Damsel bugs preferred nymphs. Field collection of predators continued for a second year. Specimens will be processed to identify if they have consumed BMSB through molecular gut content analysis. Twoprimers for gut content analysis have been identified and refined for this purpose. (3)Develop and compare monitoring methods (light based/pheromone based traps, visual and knockdown assessments) for brown marmorated stink bug that can be used to assess emergence from overwintering sites, conduct population assessments and evaluate movement between different crops: Different commercial lures were compared in blueberries and along field edges. We also monitored BMSB abundance in blueberries using black light traps. In general, BMSB populations were very low in blueberries. (4)Develop best management practices for the brown marmorated stink bug in field crops, fruit, nursery and vegetables: Trap cropping in vegetables was researched at RAREC using a sorghum and sunflower trap crop. The addition of pheromone traps within the trap crop was also assessed. There was no distinct advantage of including pheromone traps in terms of reducing stink bug injury in peppers. However, using the sorghum and sunflower trap crop increased natural enemy abundance and reduced stink bu feeding injury in 2015. The BMSB populations were much lower than native sitnk bug populations this year and the majority of the injury may have been caused by native stink bugs. (5)Deliver research based IPM recommendations to growers: Information was devlivered to growers throughout NJ at various extension meetings, particularily the North and South NJ Fruit Growers meetings and summer twilight meetings. Timely information on pest populations was delievered through the online Plant-Pest-Advisory blog and a factsheet on border-spray management was published through NE SARE. (6)Determine host plant characteristics that impact attractiveness to BMSB and identify species that could potentially be used as a trap crop, etc.: A study was initiated on comparing aggregation pheromone lures in peaches relative to observed opulations and injury. This will lead to the development of decision-based mangement programs for BMSB in peaches, which is a primary host and highly susceptible to injury. (7)Identify the impacts of insecticide applications to manage BMSB on non-targets insects.: N/A

Progress 10/01/13 to 09/30/14
Outputs Target Audience: The target audience for this work is researchers and extension educators. The results of our work will be critical in developing IPM programs for brown marmorated stink bug, an invasive pest which has been devastating to established pest management systems. While our research at this time is primarily shared with researchers and those involved in the BMSB stakeholder group, the results are picked up by this group of 50+ researchers and shared through their own extension programs. This is accomplished through undergraduate students, international graduate student exchange program and graduate student mentoring. Additionally, information is disseminated to growers at twlight meetings, regional grower meetings and through blog posts. Changes/Problems:
Nothing Reported
What opportunities for training and professional development has the project provided? This project has trained 3 graduate students, 2 postdoctoral scholars and numerous undergraduates. How have the results been disseminated to communities of interest? Research results from laboratory and field trials in peaches, grapes and organic production were disseminated to growers via two primary mechanisms: the online newsletters and grower talks. Additionally members of the group participate in the BMSB Working Group which meets twice per year to discuss and share knowledge learned regarding BMSB biology, behavior and management across commodities. What do you plan to do during the next reporting period to accomplish the goals? Research will continue on all objectives.
Impacts What was accomplished under these goals?
1. Feeding injury diagnostics by plant phenology were conducted this year and it was determined that early season feeding was highly injurious where as feeding just prior to harvest did not cause significant injury. Phenological stage dependent injury by BMSB to wine grapes was evaluated in 4 varieties at a commercial vineyard. This was the second year of data collection for this project and it validated previous year's data demonstrating that white varietals are more susceptible to BMSB feeding and that injury beginning at veraison can lead to reduced yield. 2. Natural enemy surveys using sentinel BMSB egg masses identified that predation, while low, remains the key mortality agent. Katydids were a primary predator. However, egg mortality due to predation was found at about 6% under organic management, which is significantly less disruptive to natural enemies than conventional programs. This work will be expanded to include gut content analysis and to include additional life stages of BMSB. 3. Utilize black light traps for monitoring flight activity and identify risk periods During the summer of 2014, a network of 60+ blacklight traps were installed on vegetable farms throughout NJ. These traps were used to monitor weekly BMSB activity and to create weekly geospatial maps of BMSB distribution and density. These maps were provided to growers via a website (http://www.pestmanagement.rutgers.edu/IPM/Vegetable/Pest%20Maps/maparchive.htm#2014) and PPA Vegetable Blog (http://plant-pest-advisory.rutgers.edu/rss-2/). This work showed that BMSB populations were the lowest they have been since before 2010 (<5 BMSB per night) presenting little or no risk to vegetable crops. Because of this no maps were distributed. Locations (3-6 per week) with the highest densities were presented in the PPA Vegetable blog in tabular format. Calculate the diurnal activity of BMSB adults and nymphs to identify key sampling periods A second year examining the diurnal activity of BMSB adults/nymphs was completed using 100+ tree peach orchards located at the Rutgers Agricultural Research & Extension Centers located in Cream Ridge and Upper Deerfield, NJ. This research showed that adult activity remains constant throughout the day. However, nymphs were most active 7 to 10 hours after sunrise. These results agree with results obtained in 2013. These results are currently being summarized for publication. Identify the dispersal behavior of BMSB in peach orchards A second year examining the dispersal behavior of BMSB adults/nymphs was completed using 100+ tree peach orchards located at the Rutgers Agricultural Research & Extension Centers located in Cream Ridge and Upper Deerfield, NJ. This research showed that adults and nymphs within orchards can be related to surrounding land use and varietal ripening dates and agree with results obtained in 2013. These results are currently being summarized for publication. We have completed our study on dispersal behavior of BMSB in peach using protein markers, a mark-recapture technique. Our findings suggest that there is a strong edge effect, with 85% of insects stopping at the orchard edge before moving ot the interior. Surprisingly some individuals stayed at the edge for one week. This supports work by Nielsen and Blaauw on the use of border sprays to manage BMSB. Identify the key predators of BMSB through gut content analysis Genetic markers using a short sequence of mtCOI gene have been developed and optimized for BMSB. a BLAST search in the NIH database suggests that this sequence is unique to BMSB and can be used to identify BMSB-specific DNA in predator guts. They are currently being tested for specificity. 4 and 5. Research is being conduted at multiple states on best management practices. Discussions in tree fruit are currently underway to develop recommendations for growers impacted by BMSB. 6. Identify host plant volatiles that stimulate dispersal of BMSB nymphs Work by our group has demonstrated that BMSB nymphs make host plant decisions and that these decisions correspond to maturation of fruiting structures. In 2014 we collected head space volatiles from swiss chard, sweet corn, bell peppers and soybean every two weeks throughout the growing season. The goal is to identify any chemical odors that might be driving this movement to a more suitable host plant. Samples are currently being analyzed with GC-Mass Spectrometry. 7. Assess the response of white-peach scale and San Jose scale in peaches to BMSB treatments Due to a devastating hailstorm at the end of May 2014, we were unable to conduct this research as planned. The hailstorm damaged 95% of the fruit and there was insufficient fruit to treat. Studies will be conducted in 2015.
