Non Technical Summary
The primary purpose of this project is to bring together a comprehensive team of scientists and stakeholders to develop a holistic research and extension plan to address flatheaded borer issues in multiple specialty tree crops and to identify other knowledge gaps and critical needs.Deciduous tree crops provide billions of dollars in economic impact and jobs for rural agricultural communities in the U.S., but tree damage from flatheaded borers is a major source of revenue loss in these production systems. Flatheaded borersin the genus Chrysobothris are key pests of deciduous nursery, nut, and orchard tree crops because their damage can be extensive, difficult to detect, hard to manage, and can either kill the tree or ruin the tree quality. Because flatheaded borers destroy water and nutrient conducting tissues in tree trunks, any damage is unacceptable to tree producers. If trees survive flatheaded borer attacks, they have lower nut yields or aesthetic damage that makes them unmarketable as nursery trees. The flatheaded appletree borer (FAB) (Chrysobothris femorata Olivier) and Pacific flatheaded borer (PFB) (Chrysobothris mali Horn) are the major flatheaded borer pests of specialty trees in the U.S. with damage often exceeding 40% of the crop without insecticide intervention. The Oregon Hazelnut Commission (OHC) recently ranked the PFB as their number one priority pest in young orchards. Both PFB and FAB are major drivers of insecticide use in tree crops.Tree crops have similar production practices during propagation and establishment, which increases the feasibility of developing a systems approach for flatheaded borer management in multiple specialty tree crops. Many tree producers currently use prophylactic trunk sprays of contact insecticides (e.g., bifenthrin, permethrin, or chlorpyrifos) or systemic neonicotinoid drenches (e.g., imidacloprid) to manage flatheaded borers. Most of these insecticides have broad spectrum activity on non-target organisms, are older chemical classes associated with greater acute human toxicity, and some like neonicotinoids have been under scrutiny for possible pollinator effects. Routine borer sprays are used by producers because there is a long time period between egg-laying and the first detectable borer damage. However, sprays that are poorly timed can lead to unnecessary environmental contamination, harm to beneficial insects, higher costs, and ineffective borer control. Over-use of insecticides also can increase the risk of insecticide resistance in borers.The current project will engage specialty tree crop stakeholders in development of a comprehensive management plan for flatheaded borer. State focus group meetings will be held for specialty tree crops of hazelnut (Oregon), pecan (Georgia), and ornamental nursery (former states and Alabama, North Carolina, Ohio, and Tennessee). Input from these stakeholder groups and their representative marketing organizations will be combined into an action and outreach plan during our two-day group planning meeting. Information will be compiled into a written summary and proceeding for dissemination via university extension and the Southern Region Integrated Pest Management Center (http://sipmc.org/index.cfm/center-projects/working-groups/wood-borer-working-group/). Long-term benefits anticipated from the project will include the development of a trans-disciplinary approach to solve a pest problem across multiple specialty tree cropping systems throughout the United States.

Goals / Objectives
The project goalis: To develop a comprehensive research and extension plan for addressing nursery, nut, and orchard stakeholder needs for improved, cost effective, and sustainable flatheaded borermanagement. These priorities will be developed by engaging stakeholders and a trans-disciplinary team of scientific experts to identify areas of critical need and knowledge gaps and build on collaborative interactions to develop a comprehensive management strategy for three specialty tree cropping systems that include ornamental nurseries, hazelnuts, and pecans. The project objectives are:a) To developa comprehensive IRB-approved needs assessment survey for nursery, nut, and orchard producers, extension, and state-ag to capture data on tree losses, current control methods, and costs associated with flatheaded borers. b) To summarize needs assessment survey data and share results withproducers at focus group meetings held atcollaborator states andobtainadditional producer inputon knowledge gaps and criticalneeds for project plandevelopment. c) To hold a two-day workshop and planning meeting of team members at the Conference Center of the Tennessee State University Otis L. Floyd Nursery Research Center, McMinnville, TN. d)To developa workshop proceeding of information captured from surveys, needs assessments, and workshop presentations and posting of the information on the Southern Region Integrated Pest Managementunder the newly established Wood Borer Working Group section(http://sipmc.org/index.cfm/center-projects/working-groups/wood-borer-working-group/).
Project Methods
The primary purpose of the project is to develop research and extension plans for the management of flatheaded borers in specialty tree crops. To achieve the project purpose, planning activities will focus on sharing current knowledge of flatheaded borer (e.g., Pacific flatheaded borer and flatheaded appletree borer) ecology and management, building consensus among scientists and stakeholders regarding the impact of these pests in nursery tree, nut and fruit commodities, and identifying current knowledge gaps and future research and extension objectives. Researchers will also exchange ideas for experimental techniques for working with flatheaded borers to achieve results. Needs assessment survey will be given to growers and other relevant stakeholders impacted by flatheaded borers and information obtained will be shared through producer town hall meetings in team member states to facilitate knowledge dissemination and obtain additional feedback on flatheaded borer critical needs and issues. A two-day workshop will bring team members together to identify knowledge gaps and overlapping areas of need and to prioritize achievable research and extension goals. Surveys, summaries of town hall events, and presentations and information exchanged at the workshop will be compiled into a summary and proceeding for the Southern Region Integrated Pest Management website on our Wood Borer Working Group section and information will be used to develop a comprehensive plan of priority research and extension objectives for future projects.

Outputs
Target Audience:Target audiences of this project were nursery and nut tree growers, university extension and research personnel, tree care consultants, government personnel from state agencies and federal (USDA-ARS and APHIS), agrochemical companies, landscapers, forestry personnel, and graduate students. Two planning grant flatheaded borer workshops involving stakeholders were held at the Tennessee State University Otis L. Floyd Nursery Research Center, McMinnville, TN (1-2 July 2019) and at the Oregon State University North Willamette Research and Extension Center, Aurora, OR (20 Aug. 2019). A stakeholder survey was completed by 75 participants including nursery growers (n=7), fruit and nut orchard growers (n=53), and non-grower extension and consultant personnel (n=15) from states that included Alabama, California, Georgia, Maryland, Oregon, Pennsylvania, Tennessee, Texas, and Washington. Proceedings and other outcomes of workshops were shared on the Southern IPM Center (SIPMC) website under SIPMC Working Groups under Wood Borers - Flatheaded Borers, which reaches the target audiences of the SIPMC. Changes/Problems:No major problems occurred during the project. However, we are still in the process of summarizing the nursery and nut grower and extension personnel results from our needs assessment survey. We intend to complete this summary after the project termination period and to post the data on the Southern Integrated Pest Management Center site with a target date of 1 Feb. 2020. Data will be available for referencing in the future full Specialty Crop Research Initiative proposal submission by this flatheaded borer working group. What opportunities for training and professional development has the project provided?Professional development occurred during the project in the form of the Flatheaded Borer Workshops at McMinnville, TN (42 participants) and Aurora, OR (40+ participants). In addition to nursery and nut producers who attended the workshops and the additional nursery grower town hall meeting in McMinnville, Master graduate students also participated in workshops and received training. One graduate student is pursuing research on flatheaded borers and cover crops and has benefitted directly from training received. The student also presented to extension and research personnel at the Tennessee Entomological Society meeting on flatheaded borer management in nurseries with cover crops. Nursery growers also were trained on flatheaded borer management and provided with research updates at the International Plant Propagator Society tour of the Tennessee State University Nursery Research Center (21 Oct. 2018; 160 participants), the Annual Nursery Crop Field Day in Lenoir, NC (30 Sept. 2019), South Valley Tree and Vine Nut and Citrus Conference, Tulare, CA (20 Nov. 2019; ~60 participants), and California Walnut Board-Entomology Production Research Action Committee Meeting, Sacramento, CA (27 Nov. 2019; ~30 participants). How have the results been disseminated to communities of interest?Results have been distributed directly to producers by research scientists and extension personnel interactions on farm, as well as workshops in Tennessee and Oregon, a town hall meeting in Tennessee, and field day presentations in participant states. A flatheaded borer section has been established under the Wood Borer Working Group on the Southern Integrated Pest Management Center (SIPMC) (https://southernipm.org/partners/working-groups/wood-borers/flatheaded-borer/), which includes the Proceedings from the Flatheaded Borer Workshop in McMinnville, TN. The SIPMC site is the central source for IPM-related information in the southern region. The site is publicly available to any producer or other interested party and the proceedings specifically can serve as a needs assessment for researchers and Extension personnel. The stakeholder needs assessment survey results are still being processed, but we are targeting 1 Feb. 2020 for posting of the data summary on the SIPMC site. What do you plan to do during the next reporting period to accomplish the goals?The project has ended and there is no future reporting period. We do intend to complete the data summarization from the needs assessment survey with a target date of 1 Feb. 2020. A new pre-proposal has been prepared for a full Specialty Crop Research Initiative proposal and the working group established as a result of this planning grant intends to prepare a new full proposal submission based on the information and knowledge gathered during this planning grant process (if the pre-proposal review allows a full proposal submission).

Impacts
What was accomplished under these goals? The IMPACTS of this planning grant project included: 1) establishment of an interdisciplinary team of research and extension personnel from university and USDA agencies in the western, eastern, southern, and Midwestern U.S., who serve tree crop stakeholders in nursery, fruit trees, and hazelnut, pecan, and walnut nut orchards, 2) identification of critical stakeholder needs in these tree crop groups via a national needs assessment survey, a grower town hall meeting, and 2 grower/scientist planning grant workshops held in eastern (Tenn. State Univ. Otis Floyd Nursery Research Ctr., McMinnville, TN [TSU-NRC]) and western (Oregon State Univ. North Willamette Research & Extension Ctr., Aurora, OR [OSU-NWREC]) U.S. (producers identified in these regional groups will continue to serve as a core stakeholder advisory group for future wood borer working group activities), and 3) development of a comprehensive pre-proposal for a full Specialty Crop Research Initiative grant proposal targeting identified stakeholder goals. The list of identified stakeholder critical needs from Tennessee and Oregon workshops can be found in the Proceedings of the Flatheaded Borer Workshop posted on the Southern Integrated Pest Management website (https://southernipm.org/partners/working-groups/wood-borers/flatheaded-borer/), which also includes the summaries of the National Plant Diagnostic Buprestid Detections in North America and the Tennessee nursery grower town hall meeting. The major flatheaded borer critical needs identified for these tree crop grower industries were: 1) new insecticide or biopesticide options including rotational alternatives for the limited systemic insecticide options to reduce resistance development, optimization of application methodology, improved treatment timing for greater efficacy, and methods to reliably induce tree attacks for product testing studies, 2) improved flatheaded borer biological control including development of entomopathogenic nematodes (EPN) to augment chemical options, better EPN field deployment strategies, and identification of other natural enemies in the crop system like parasitoids and their importance, 3) improved taxonomy of the flatheaded borer species attacking nursery, nut, and orchard trees in the Chrysobothris genus, including molecular and cuticular hydrocarbon tools paired with traditional morphological taxonomy, 4) phenology of flatheaded borers in tree systems including clear understanding of oviposition timing and adult beetle activity across regional tree-growing areas to improve treatment timing, 5) flatheaded borer biological data including life history studies of key species in the systems, pathogen interactions, origin and patterns of invasion into tree crops, larval development factors, etc., 6) improved adult attractants and trapping, which is critical for determining activity patterns, timing treatments and development of mass trapping efforts, 7) production related factors and their relationship to tree attacks, new cultural control methods, better understanding of tree stress factors leading to tree attacks, and alternative production methods (e.g., tree wraps), 8) outreach to address grower needs including a comprehensive extension program for borer management in each tree cropping system, damage recognition and treatment timing recommendations for regional areas, 9) economic and social assessments including complete cost-benefit assessment of all strategies developed in items 1-8, impacts of treatment option loss (e.g., regulatory action) or value-added benefits of treatments post-harvest, and social impediments to new method adoption. A complete list of key Chrysobothris species has been developed (SIPMC website; Table 1, p. 67) that includes needs assessments for advanced molecular diagnostics and the current state of knowledge about the species like ease of trap collection, known larval tree hosts, range distribution, ecological importance, and pest status. Some of the key flatheaded borer species have been submitted for preliminary whole genomic assessment, which will benefit future projects. Specific project outcomes are described below for the 4 project goals that included 1) development of a comprehensive IRB-approved needs assessment survey for nursery, nut and orchard producers, extension personnel, and state-ag to capture data on tree losses, control methods, and costs associated with flatheaded borers, 2) summarize the needs assessment survey data and share results with producers at focus group meetings at collaborator states, 3) hold a two-day workshop and planning meeting at the Conference Center of the TSU-NRC, and 4) develop a workshop proceeding of information captured from surveys, needs assessments, and workshop presentations and post on the Southern Integrated Pest Management Center (SIPMC) website under a newly established Wood Borer Working Group. For objective 1, a needs assessment survey to identify key problems, control methods, and estimated flatheaded borer losses was prepared for three target groups, including nursery, nut & orchard producers, and non-growers (research/extension or other). The survey was assigned an exempt status by North Carolina State Univ. (NCSU) IRB Committee under Title 45 Part 46 CFR for NCSU Assurance No.# FWA00003429 (IRB Protocol 16612) and was approved by participant IRB Committees at Auburn Univ., Oregon State Univ., Tenn. State Univ., and Univ. of Georgia. The survey was hosted on NCSU website with confidential content protected by NCSU protocols. A total of 75 participants completed all or a portion of the survey from states listed under Targeted Audiences. The second objective to summarize the needs assessment survey is on-going with a target date of Feb. 1, 2020 for completion and posting on the SIPMC website. The survey was available through September and a large quantity of data for 42 questions is presently being coded for statistical program summary. If results are suitable for a journal, an additional outlet could be the Entomol. Soc. Amer. J Integrated Pest Mgmt, which publishes extension-type data. For objective 3, a 2-day workshop and planning meeting was held at TSU-NRC on 1-2 July 2019. The workshop had 42 in-person or Zoom participants including university personnel from Auburn Univ., Clemson Univ., Univ. Georgia, North Carolina State Univ., Oregon State Univ., Tenn. State Univ., Texas A&M Univ., Univ. California, Univ. Florida, and Univ. Tenn.; USDA-ARS participants with Horticultural Insects Res. Lab. (Wooster, OH), Fruit & Tree Nut Res. Lab. (Byron, GA), National Arboretum (McMinnville, TN); USDA-APHIS-PPQ; state agencies including Florida Division of Plant Industries and Tenn. Dept. Agric.; grower representing agencies including AmericanHort and IR-4 Program; industry representatives with Bartlett Tree Experts and BASF Corp.; and grower stakeholders from Hale & Hines Nursery, Hidden Valley Nursery, Moore Nursery, Plantation Tree Co., and an unspecified horticulturist. Flatheaded Borer Workshop details are in the proceedings posted on the SIPMC, including critical needs (p. 64), National Plant Diagnostic Buprestid detections in North America (p. 53), Tenn. nursery grower town hall results (p. 57), and attendee list (p. 68). The key outcomes, agenda, and participants at the OSU-NWREC stakeholder workshop are also in the SIPMC post proceeding (p. 62). The fourth objective of the project was to develop a workshop proceeding, which has just been detailed and is presently on the SIPMC website.
