Non Technical Summary
The Florida Panhandle has a landscape consisting of a mosaic of natural vegetation, forests and field crops. Peanut and cotton are the prevalent crops, with approximately 150,000 and 100,000 acres, respectively. Region-specific research and information are needed to develop integrated pest management (IPM) recommendations for growers in this area. In peanut, the development of pest management decision-making based on an IPM framework is needed. In cotton, with almost 100% of the cultivars representing Bt technology, there is need for IPM programs that accommodate this technology, since arthropod pests such as mites, trips, stinkbugs and aphids are not targets of Bt technology, and reports indicate an increase in their occurrence. In addition, IPM for Bt cotton has relevance since there is the risk of the evolution of resistance of target pests to Bt toxins. This should be taken into consideration when designing strategies to delay the evolution of resistance in an IRM approach. In addition, the future possibility of Bt soybean in the U.S demands a better understanding of the role of this crop as a source of unselected pest populations to Bt toxins, such as Cry1Ac. Carinata is a new and emerging winter/spring cultivated crop in the Florida Panhandle, and it is suitable for the biofuel industry. As a new crop in the region, there is need for a complete inventory of the pest species associated with the crop, and research to support the development of a carinata IPM program. Finally, the Florida Panhandle, and especially the Gulf Coast region, is a likely pathway of introduction of quarantined pests. This project will contribute to a statewide pest-monitoring network for the early detection of the quarantine pests H. armigera and Tuta absoluta.

Goals / Objectives
Document and characterize the spatial and temporal occurrence and population dynamics of arthropod pests in severalfield crops in the agricultural landscape of the Florida Panhandle. The long-term contribution will be to improve pest management decision-making and efficiency in the agriculture of the region.Determine the economic impact of regional peanut pests, based on the relationship between pest density and yield loss. The long-term objective is to support the development of economic injury levels and economic thresholds and develop an improved monitoring system for detection of the pest activities in peanut. It is particularly important to focus on early detection and the development and validation of sampling plans.Screen peanut cultivars and germplasm for host plant resistance in collaboration with the peanut breeding program in order to identify variability and sources of resistance in breeding lines. Laboratory and field studies will be performed to evaluate the mechanisms of antibiosis and antixenosis.Contribute to the IRM for the southeastern U.S. considering a framework complimentary to an IPM approach in Bt crops. Research on the ecology, behavior and operational factors that influence insect resistance evolution will be conducted in collaboration with other states to provide more comprehensive recommendations for IPM/IRM.Characterize the ecology of the arthropod pests associated with carinata, addressing parameters of pest survival, fecundity, number of generations, injury, seasonal occurrence, and economic damage.Contribute to a statewide pest-monitoring network for early detection of the quarantine pests H. armigera and Tuta absoluta, with the investigation of methods of trapping.
Project Methods
The documentation of the seasonal occurrence and abundance of the pests associated with field crops and carinata will be conducted in the Florida Panhandle. At a spatial scale, the agroecosystem structured with the prevalence of cotton and peanut, other neighboring crops, and wild hosts will be characterized with respect to how it affects the population dynamics of polyphagous pests though the season, especially in the case of Lepidoptera (e.g. H. zea). On a temporal scale, the ovipositional and feeding preference of the pest will be determined for specific phenological stages of the plants with respect to early and late-planted crops, different crop cultivars, Bt technology and cropping systems in the Florida Panhandle (e.g. irrigated versus dryland). Information concerning the effect of biological controlsand the effect of the abiotic factors and their variability in the ecological transition climatic zone of the Gulf Coastal Plain on the survival of pests will also be determined. For that, experimental plots at West Florida Research and Education Center (WFREC) in Jay, FL and commercial fields in the Florida Panhandle will be sampled with pheromone traps to survey the presence of Lepidoptera. The samples will be screened at the Entomology Laboratory at the WFREC. Larval sampling will also be conducted. Plant inspection, destructive samples, ground cloth samples, and sweep net samples will be taken at ten locations along a transect across each field. The average plant growth stage will be recorded at sampling. The insects collected in each field will be held in containers, transported to Entomology Laboratory at the WFREC, and the emergent adults will be identified to species. The data will be analyzed to document the seasonal pest abundance and field crop utilization in the Florida Panhandle for species such as H. zea, Spodoptera frugiperda, Chrysodeixis includens, etc. In addition, surveys with pheromone traps for early detection of H. armigera and T. absoluta will be conducted as a contribution to the statewide and regional pest detection program of the Cooperative Agricultural Pest Survey (USDA/CAPS).A stock colony of select Lepidoptera species will be established and reared on artificial diet, at 25ºC and photoperiod of 16:8 [L:D] h, to provide a supply of larvae for laboratory, greenhouse and field experiments. Studies will be conducted at WFREC to screen peanut and carinata genotypes for pest resistance by attraction studies, consumption assays, and effect of host plant in the reduction of growth, inhibition of reproduction, or induction in behavioral abnormalities in pests. In addition, larval consumption and the relationship between larval density, plant injury and yield will be characterized.

Additionally, as a row crop entomologist based at the WFREC, my clientele also includes the general public, particularly middle and high school students and community and state leaders. I have used information on pests and beneficial insects to promote science literacy and build awareness of the values of IPM. What do you plan to do during the next reporting period to accomplish the goals? Nothing Reported

Impacts
What was accomplished under these goals? Brassica carinata has the potential to become an economical biofuel winter crop in the Southeast U.S. and studies for the development of an IPM program were performed, including the inventory of pest occurrence, pest position within the canopy, and the impact of defoliation on B. carinata yield. Developing and validation of IPM tools to peanut producers. For the first time in the U.S., the seasonal flight of soybean looper using year-round trapping was documented, including a complete inventory of Plusiinae species cross-attracted to the commercial pheromone lure (Shaw et al., 2021). Improvement in pheromone trapping of soybean looper has been possible by collaboration with researchers from the southern U.S. and industry, which involved testing a more specific pheromone formulation for this species (Fleming et al., 2021). Host plant resistance is another IPM tool has been explored for peanut. A collaborative work with peanut breeders from southeastern U.S. has been documented host plant resistance in breeding lines of peanut. The new peanut cultivar "Walton" (Balota et al., 2021), launched in 2021, besides agronomic desired characteristics, has antibiosis resistance to soybean looper. Improvement of the technology of management of soybean looper has been under validation, based on larval behavior studies and using the canopy opener technology (Rabelo et al., submitted). The predation potential of lepidopteran pests by Solenopsis invicta (red imported fire ant) is now documented as a natural biological control agent in cotton and peanut in the Florida Panhandle (Baldwin et al., 2020). Collaborative work with researchers from U.S. documented the current distribution (Huseth et al., 2021) and information for correct identification of pests associated with soybean supporting management decisions (Hodgson et al., 2021), in addition to the estimation of economic thresholds for management decision (Justus et al., 2022). Documented the susceptibility and demographic performance of target and non-target pests of Bt technology (Rabelo et al., 2020). The performance of the transgenic Bt technology in the Florida Panhandle have been contrasted with other states (citations Yu et al., 2021; Ni et al., 2021; Reisig et al., 2018). Contribution to the review of the national Bt cotton and corn IRM policy in the U.S. serving in the EPA scientific advisory panel "Resistance of lepidopteran pests to Bacillus thuringiensis (Bt) plant incorporated protectants (PIPS) in the United States." This panel generated recommendations that have been used in the refinement of national IRM policy for transgenic Bt crops. Development of an innovative approach to assessing susceptibility of lepidopteran pests to broadly adopted insecticides and associated risks of control failure (Rabelo et al., 2020). Estimation of the risk of insecticide resistance to commonly adopted insecticides in the Florida Panhandle in row crops, including populations of eight economic lepidopteran pests. The first case of resistance of beet armyworm to the novel diamide insecticides was documented and a study of the stability of the resistance has been conducted, with results directly impacting in the management recommendations of this pest in row crops in the U.S (Rabelo et al., submitted). The susceptibility and demographic performance of cotton bollworm, a target pest by Bt technology was documented. Collaborative studies with USDA/APHIS, Australia, and Brazil on the invasive species H. armigera, the invasive old-world bollworm. The timeline of the pest's spread in South America (Specht et al., 2021), its life history traits (Silva et al., 2020), a post-invasion genetic characterization (Silva et al., 2018; Valencia-Montoya et al., 2020), and niche inter competition with other economic noctuid pests in the Americas (Bentivenha et al. 2016a and b, 2017a and b) have been documented. Based on the risk of future entrance and potential establishment of H. armigera in the continental U.S being extremely high, she cooperatively conducted a pheromone trapping and larval sampling study of this species in commercial fields in the Florida Panhandle, a possible migratory route from the Caribbean to the U.S. This work confirmed that H. armigera is currently not present on the U.S. Gulf Coast. This information is highly important to agriculture in the U.S. because establishment of H. armigera could cost producers billions of dollars in production of major crops such as cotton, corn, and specialty crops. The fall armyworm, Spodoptera frugiperda, is currently an outbreak invasive species in Africa, Asia, and Australia and information developed by Dr. Paula-Moraes's program has been documenting the ecology and genetics of this species the Florida Panhandle. Additional studies, with collaboration with other states and specialists from South America has been used to support IPM recommendations and validate the use of refuge areas as an IRM strategy (Gonçalves et al., 2020). An extensive list of host plants (Montezano et al., 2018) of this pest in Americans has been produced, with essential information on the life history traits of this species on transgenic Bt crops, detailed data on oviposition behavior, and a greater understanding of on-plant larval movement and feeding behavior (Pannuti et al., 2019). These results have contributed for the development of IPM/IRM in Asia and Africa.

Target Audience:Farmers, ag professionals, researchers, undergrad and grad students, general public Changes/Problems: Nothing Reported What opportunities for training and professional development has the project provided? Nothing Reported How have the results been disseminated to communities of interest? Nothing Reported What do you plan to do during the next reporting period to accomplish the goals?A new Hatch project will be submitted.

Impacts
What was accomplished under these goals? During the period of the report the followingaccomplishments were reached: The seasonal flight of lepidopteran pests has been documented. In collaboration with APHIS/USDA, year-around monitoring for the invasive species H. armigera was conducted via pheromone trapping and larval sampling in commercial fields. Specimens cross-attracted to H. armigera have been identified using DNA analysis by APHIS, and this targeted species has not been detected in the state of Florida during the period reported. Study of host plant resistance of peanut lines to Chrysodeixis includens were performed and in collaboration with breeding specialists from Virginia Tech, Clemson University, and University of Florida the resistance by antibiose was documented in the new virginia-type peanut cultivar "Walton" (Reg. no. CV-146, PI 695073). Field derived colonies of lepidopteran pests associated with row crops in the Florida Panhandle has been established at WFREC, and the insecticide susceptibility documented. Collaboration with other states from southeastern U.S has allowed documentation of the incidence of cotton aphids in the region, the performance of insecticides, and validation of field trapping.

Impacts
What was accomplished under these goals? Several research activities have been performed under this Hatch project. The seasonal flight o lepidopteran pests has been documented. The regional occurrence of Solenopsis invicta and its predation potential of lepidopteran pest eggs, including those of Helicoverpa zea, were documented. In collaboration with APHIS/USDA, year-around monitoring for the invasive species H. armigera was conducted via pheromone trapping and larval sampling in commercial fields. Specimens cross-attracted to H. armigera have been identified using DNA analysis by APHIS, and this targeted species has not been detected in the state of Florida. Field derived colonies of lepidotperan pests associated with row crops in the Florida Panhandle has been established at WFREC, and the insecticide susceptibility documented, including the first report of resistance of Spodoptera exigua to diamide. Life history trait studies were performed and the demographic performance of populations of H. zea, including collections from Bt and non-corn, was documented for dual and triple-gene Bt cotton traits in different areas of the region. Helicoverpa zea overwintering survival studies continue under Florida Panhandle conditions, including studies examining survival rate and infestation levels in corn and other hosts late in the crop crop season, such as cotton, peanut, and soybean. Collaboration with other states from southeastern U.S has allowed documentation of the incidence of cotton aphids in the region, the performance of insecticides, and validation of field trapping. In addtion, the susceptibility of targeted species to Bt technology has been performed. International collaboration with Brazil and Australia have been allowed studies of the invasive species H. armigera.

What do you plan to do during the next reporting period to accomplish the goals?In the next reporting period the activities will continue to be performed to reached the objetives of the project. Moreover, grants will be submitted to support complementary studies associated with the current objetives.

Impacts
What was accomplished under these goals? 1. Since June 2017, pheromone trapping and pest sampling have been performed in commercial fields and experimental areas in the Florida Panhandle to document the spatial and temporal occurrence of pest species. 2. Experimental areas of peanut at WFREC have been sampled todocument the prevalent species associated with this crop in the Florida Panhandle. This represents the first step todefine species of pests that should have documented therelationship between pest density and yield loss. 3.A small plant growth unit to evaluate resistance of peanut genotypes was developed using white plastic pipe cylinder (15cm high x 7.6cm diameter) and filled with sand soil. This unit will be used to evaluate sources of resistant in peanut genotypes, based on larval survival and development, and plant injury rating; 4.Several activities have been performed in order to document the ecology, impact of pests and the baseline susceptibility to insecticides of several species of lepidopterans associated with field crops in the Florida Panhandle. A collaborative work with other states in southeastern U.S has been also developed in order document the susceptibility of H. zea to Bt toxins. Results of bioassay with Cry1Ac demonstrated a range of susceptibility of H. zea across the southeastern United States, indicating that it is probable that resistant populations are common. In the same way, the first documentation of field resistance of H. zea to Bt corn in the U.S. mid-south region has been performed, documenting the susceptibility levels to Cry1A.105 and Cry2Ab2. The results indicated a mosaic distribution of the resistance in the region of H. zea populations collected in Louisiana, Georgia, and Florida. 5. A pest survey in Brassica carinata has been conducted through samplings in commercial fields and in experimental area with 16 genotypes. The occurrence of pests has been sampled weekly by plant inspection. In each plot, one B. carinata plant is divided in three canopy zones (upper, medium and lower canopy) and inspected for the presence of pests. The biology and defoliation potential of yellowmargined leaf beetle (YMLB) were evaluated in laboratory and greenhouse in a CBD. The survival and development of YMLF feeding on carinata leaves were performed in growth chambers, held at 25ºC/24h dark. In greenhouse, a feeding study was performed in order to measure the larval and adult defoliation potential. The overall results indicated that diamondback moth was the predominate species associated with commercial fields of carinata. The preliminary results from laboratory and greenhouse indicated that larval survival of yellowmargined leaf beetle was around 40%, feeding occurred during 9 days (±2.4), causing 5% defoliation, and the pupal weight was 0.0088 g (±0.0006). 6. The pheromone trapping conducting at WFREC has not been detected the presence for H. armigera and other species of invasive species of Lepidoptera.
