What opportunities for training and professional development has the project provided?I have offered three presentations, six in-service trainings, and sixteen hands-on trainings from 2011 through 2017 to increase the ability of stakeholders to monitor and identify key pest and beneficial arthropods associated with horticultural crops in Florida. More than eight hundred participants have benefitted from these trainings, including extension agents, crop advisors, growers, master gardeners, industry representatives and graduate students in the agricultural sciences. Trainings have been offered in Hendry, Hillsborough, Manatee, Palm Beach, Polk and St. John's counties in collaboration with UF/IFAS extension personnel Gene McAvoy, Alicia Whidden, Crystal Snodgrass, Lisa Hickey, Mary Beth Henry, Anne Yasalonis, Chris Miller, James DeValerio, Cami McAvoy, Bonnie Wells and Mark Warren. UF graduate students Nicole Casuso and Jeff Cluever played a crucial role in developing and delivering the learning tools for these workshops, including co-producing 15 photo identification guides and a hands-on tool for identifying thrips to the species level. UF faculty who have collaborated in the delivery of these trainings include Drs. Amanda Hodges, Norm Leppla, Joe Funderburk, Lance Osborne, and Adam Dale. Through one in-service training, three statewide Polycom presentations and thirty-two grower meeting presentations from 2011 through 2017, I have communicated with approximately one thousand five hundred participants regarding sustainable approaches to pest management and insecticide resistance management. The audience in these meetings consists of growers, crop protection consultants, extension agents, and industry representatives. The primary venues for these presentations are annual grower meetings organized by UF/IFAS extension agents Crystal Snodgrass (Manatee County) and Alicia Whidden (Hillsborough County), and Regional Extension Director Gene McAvoy (Hendry County). I also present each year at the annual meeting of the Florida Tomato Institute in Naples and at the Florida Ag Expo at GCREC. Faculty collaborators include Joe Funderburk and Phil Stansly. How have the results been disseminated to communities of interest?Results have been disseminated to the scientific community through the publication of 19 articles or book chapters between 2013 and 2017. I have made twenty presentations at national, regional and state level scientific meetings during the course of this project, and graduate students under my mentorship have collectively made seven presentations of results at scientific meetings. I have co-authored 93 extension publications during the course of this project, including 64 Electronic Data Information System publications with the University of Florida, nine articles in the Florida Tomato Institute proceedings, ten reports in Arthropod Management Tests, and ten newsletter articles. In addition, results have been disseminated at the thirty-two grower meetings, sixteen hands-on trainings, and seven in-service trainings outlined above. What do you plan to do during the next reporting period to accomplish the goals?

What was accomplished under these goals?
I have demonstrated that resistance among whiteflies to neonicotinoids is variable across the state, but that as resistance to one neonicotinoid increases in a given population, resistance to others increases (cross-resistance is common). In addition, I was the first to document cross resistance between neonicotinoid insecticides and the new "pollinator-friendly" butenolide insecticide flupyradifurone. This research was published in the journal Insects (Impact Factor 1.94). My research program evaluates pest management methods in combination in order to reduce over-reliance on insecticides and their negative impacts. Synergistic effects of combining repellant metalized plastic mulches, host plant resistance and biopesticides are evaluated for suppression of virus vectors. Integrated factors are evaluated using replicated split plot and randomized complete block designs at the Gulf Coast Research and Education Center or on-farm with collaborating growers. Biopesticides are distinct from conventional insecticides in that they tend to be less harmful to pollinators and beneficial insects. Biopesticides tend to exert less selection pressure than conventional insecticides, and so are less likely to contribute to the development of insecticide resistance. I have carried out field trials demonstrating the efficacy of conventional, non-neonicotinoid insecticides for protecting the tomato crop from Tomato yellow leaf curl virus during the first five-week treatment window, when infection produces the greatest impact on yield. Results have been published in the Florida Entomologist (Impact Factor 0.975) and Journal of Insect Science (Impact Factor 1.04). I carried out the first survey of thrips species associated with Florida strawberries. My program demonstrated that thrips species respond differently to insecticides, which can decimate native species and allow more damaging, insecticide-resistant thrips species to predominate. This research and the first photo-based identification key of thrips associated with Florida's horticultural crops have been published in the Florida Entomologist. This research builds on Dr. Joe Funderburk's work with thrips in fruiting vegetables. Understanding the role of weeds as hosts of pests, diseases and beneficial arthropods is crucial for the development of sustainable pest management programs. Weeds can contribute to a pest problem by serving as a reservoir for pest and disease, or they can help alleviate pest pressure by providing habitat for predators and parasitoids that suppress pests. I developed a novel approach to evaluate the importance of weeds as hosts of Tomato yellow leaf curl virus, and demonstrated that of the four most common weeds in central Florida, one (Amaranthus retroflexus) is a host of Tomato yellow leaf curl virus, while three are not (Bidens alba, Emilia fosbergii, Raphanus raphanistrum). This research was published in Environmental Entomology, which has an Impact Factor of 1.59 and is one of the premier journals of the Entomological Society of America. Additional research on the role of weeds, published in the journal Insects (Impact Factor 1.94), confirmed that Bidens alba plays a positive role in mitigating whitefly populations by supporting high densities of whitefly parasitoids. Biopesticides offer an important alternative to conventional insecticides including neonicotinoids, and are one of the few options for organic growers. My research with biopesticides and biological control provides pest management guidelines for Florida's small but growing certified organic and protected agriculture sector. My program demonstrated the importance of plant connectivity in the dispersal of the predatory mite Amblyseius swirskii for management of broad mites on greenhouse bell pepper. Research on A. swirskii has been published in the Journal of Economic Entomology (which has an Impact Factor of 1.84 and is "the most cited entomological journal" according to its website), the Journal of Insect Science (Impact Factor 1.04) and Plant Health Progress (Impact Factor 0.29). My contributions to pest management science include: demonstrating the role of weeds in managing whiteflies (Bemisia tabaci) and Tomato yellow leaf curl virus; demonstrating that whitefly populations are variable in their susceptibility to neonicotinoid insecticides, but that cross resistance is common; demonstrating that cross resistance can develop between neonicotinoid insecticides and butenolide insecticides: therefore butenolides should be grouped with neonicotinoids for purposes of resistance management; demonstrating that thrips species respond differently to insecticides, and that insecticide applications can lead to the predominance of resistant invasive thrips species; demonstrating that biopesticides and host plant resistance can contribute to pollinator-friendly pest management guidelines and offset the development of insecticide resistance; demonstrating that plant connectivity is essential for the effective use of predatory mites in protected agriculture.

Target Audience:The target audience we have reached during this reporting period includes producers of vegetable, berry, ornamental and landscaping plants, industry representatives, extension agents, master gardeners, home gardeners, and other crop protection professionals including pesticide applicators, crop consultants, and contract researchers. Changes/Problems:The only major change to report is the detection of the Q biotype of Bemisia tabaci in the Florida landscape. The Q biotype has the reputation of being harder to control than the B biotype, which is also known as the silverleaf whitefly, and which is the whitefly established in Florida horticultural production. Because of the detection of the Q biotype in the Florida landscape, we are directing resources toward assessing the threat the Q biotype may pose to Florida agriculture. What opportunities for training and professional development has the project provided?We have offered trainings at seven meetings for growers and industry and four hands-on pest identification workshops.

Spring issue. http://gcrec.ifas.ufl.edu/media/gcrecifasufledu/docs/pdf/berry-newsletter/berry-newsletter/Spring-2016.pdf. What do you plan to do during the next reporting period to accomplish the goals?We will continue field trials evaluating the potential of biopesticides to control whiteflies, Tomato yellow leaf curl virus and irregular ripening in tomato, and continue our resistance monitoring program to evaluate the susceptibility of the silverleaf whitefly to imidacloprid, thiamethoxam, buprofezin, pyriproxifen, and spirotetramat (insecticides commonly used in vegetable production). We will continue evaluations of the predator Dicyphsu hesperus for control of silverleaf whitefly in greenhouse tomato. We will survey Florida tomato fields for the presence of the Q biotype of Bemisia tabaci (the silverleaf whitefly is the B biotype of Bemisia tabaci). In addition, we are evaluating optimal approaches for managing the diamondback moth, a key pest of cole crops which has re-emerged as a priority for growers of cabbage and other brassicas across the state and region.
Impacts
What was accomplished under these goals?
We demonstrated that resistance among whitefly populations to neonicotinoid insecticides is quite variable in tomato producing regions across the state, and that resistance in some cases is quite high. Neonicotinoids are very much a matter of public and regulatory concern, because of the perception that they have a negative impact on pollinators. Our research with biopesticides has identified "softer" insecticides that may be used in the field and greenhouse as alternatives to neonicotinoids in some instances, namely insecticidal soaps, stylet oils and some new products that are not yet registered. The development of less toxic approaches to manage whiteflies and other pests in greenhouse production is particularly important because of the restrictions on insecticide use in enclosed production, and the need for insecticides that do not impact the commercial pollinators that are needed for the prodcution of tomato, peppers and other crops in protected culture. To that end we have initiated research on managing whiteflies in greenhouse tomato with the commercially available predator Dicyphus hesperus.

Approximately 486 clients participated in these meetings. What do you plan to do during the next reporting period to accomplish the goals?I will be focusing on evaluating biopesticides for management of silverleaf whitefly and Tomato yellow leaf curl virus during the next reporting period. I will initiate studies on the whitefly predator Dicyphus hesperus for control of whiteflies in the greenhouse, and resume studies evaluating resistance of silverleaf whitefly to imidacloprid and thiamethoxam.
Impacts
What was accomplished under these goals?
We demonstrated that Frankliniella bispinosa, the most common thrips in Florida strawberry, is susceptible to most insecticides while the invasive Frankliniella occidentalis is not. We demonstrated that Frankliniella schultzei is present in strawberry in Hillsborough County at low numbers. We carried out trials demonstrating the efficacy of combining virus resistant tomato, metalized mulch and insecticides to manage Tomato yellow leaf curl virus and silverleaf whitefly. We demonstrated the efficacy of a range of biopesticides for managing silverleaf whitefly in greenhouse tomato.

Greenhouse and field studies were carried out to evaluate and compare new insectcides for management of Bemisia tabaci and Tomato yellow leaf curl virus. Materials evaluated include flupyradifurone, cyazypyr and pyrifluquinazon, each of which is nearing registration for use by vegetable growers in the US. Field trials were carried out to evaluate the efficacy of new and establsihed materiasl for management of pepper weevil, broad mites, caterpillars, and spider mites in vegetable crops. Greenhouse studies were carried to determine if key weeds of Florida agricultural fields are hosts of Tomato yellow leaf curl virus. Field studies evaluated the comparative suitability of weeds as hosts for Bemisia tabaci and parasitoids of B. tabaci.
