Non Technical Summary
In 2011, Arkansas had 48,300 farms with a total of 13.5 million acres of farmland, and was home to 28,000 cattle operations. Agriculture is responsible for more than 256,000 jobs - one in six jobs in the state. Losses due to insects, weeds and diseases represent the largest preventable costs to agricultural growers in Arkansas. With expensive new seed technology in row crops, growers try to protect the investment made at planting because of varieties that confer resistance to selected herbicides and insects. Pesticides represent one approach to pest management, but we face the consequences of over-reliance on this approach; thus the need for research on integrated pest management (IPM) solutions. Arkansas cattle growers rely on research-based IPM information and strategies, whether to control pests directly on the cattle (e.g., flies, ticks) or pests of forage and pasture (e.g., fire ants, armyworm). Arkansas crop growers have traditionally used many individual IPM methods developed by researchers and extension personnel, but integrating methods needs improvement. Our applied entomology program conducts near-term research to produce solutions for agricultural producers, county agents, consultants and crop scouts about integrated pest management. Educated growers can assess information from scouts and consultants to make better pest management decisions, optimize IPM tactics and use pesticides as needed. Trained consultants are less likely to recommend use of pesticides if they recognize pests and understand thresholds. IPM helps cattle producers farm more efficiently and reduce reliance on pesticides, and our program will develop solutions that can be delivered to cattle and dairy growers and consultants.

Goals / Objectives
1) Develop improved IPM programs for crop growers, consultants and scouts, for greater IPM adoption, and increased economic and environmental benefits; 2) Conduct applied research in agronomic crops to develop robust economic thresholds; 3) Develop improved IPM programs for cattle growers (including dairy), for greater IPM adoption, and increased economic and environmental benefits..
Project Methods
Crop Pest Management The primary method of delivery of demonstrations is through on-farm research trials and field days. In recent years, the needs from county agents have increased, due to changes in crop acreage planted and threats from new pests. Target audiences are growers, consultants, farm supply store personnel, and crop protection applicators. Economic thresholds are the basis for making informed IPM decisions. Changes in crop varieties or agronomic practices have made older thresholds inappropriate, or at least needing revisited. Management of key pests requires an updated economic threshold to help Extension recommendations for appropriate IPM methods, particularly whether or when treatment is necessary Thresholds for rice stink bug are long outdated, particularly with modern varieties and changes in growing practices. We will establish on-station (Rice Research and Extension Center) trials to evaluate the threshold for rice stink bug, using current varieties and agronomic methods (e.g., herbicides, flood and soil fertility). The updated economic threshold for rice stink bug will be demonstrated at field days. Insecticidal seed treatments can provide extended protection of crop plants, especially in young plants. The insecticides are translocated systemically throughout the plants, conferring benefits for up to several weeks. We will conduct studies on Research Stations and in growers fields to assess the benefits of seed treatments, based on history of pest pressure in the fields, as well as by comparing damage and insect numbers in seed-treated and conventionally treated fields. Animal Pest Management Evaluations of phorid fly abundance and presence involves the use of a sticky type traps using either live or dead ants as the bait (Farnum and Loftin 2010). Although this method is very effective in capturing Ps. curvatus, its efficacy at capturing other species (Ps. tricuspis and Ps. obtusus) is unknown. We will modify the current sticky trap to evaluate different baits (food vs. dead ants vs. live ants) and compare trap catches to collections made by mechanical aspiration. We also will increase awareness of fire ants in northern Arkansas, to identify and control new fire ant infestations that originated from importation of baled hay from infested areas. Where new infestations are found, we will conduct demonstrations of control methods to landowners. We plan evaluations to demonstrate the value of alternative insecticide formulations (e.g., insect growth regulators) targeting fall armyworm with longer residual activity. During 2012, fall armyworm pressure was sustained with overlapping generations, which resulted in some producers making two or three pyrethroid applications. One or two applications could have been avoided if products with longer residual activity had been used. We will develop test sites in response to reports of armyworm pressures, where we will compare efficacy and residual benefits of pyrethroids versus alternative insecticides.

Outputs
Target Audience:Agricultural growers (crop and animal), crop consultants, Extension faculty, entomological scientists Changes/Problems: Nothing Reported What opportunities for training and professional development has the project provided?Two MS students and one PhD student completed advanced degrees based on research on developing solutions and treatment thresholds for major pests. Those students have shown their results at field days and scout schools to demonstrate research results to growers, crop consultants and crop scouts, in addition to presentations made at professional meetings. How have the results been disseminated to communities of interest?Crop scout schools, IPM demonstrations, field days and county-level education meetings provided research results and recommendations to agricultural producers. Research results have been presented at state, regional and national professional meetings, and published in a range of Experiment Station Reports, Conference Proceedings and professional journals. What do you plan to do during the next reporting period to accomplish the goals? Nothing Reported

Impacts
What was accomplished under these goals? We continue to address pest management challenges faced by crop and animal growers in Arkansas. Our entomological research resulted in a greater understanding of crop pests and their dynamics, and developing and delivering solutions for growers to use to manage pests of field crops and cattle, while minimizing environmental impacts. We conducted applied field research projects designed to manage crop pests such as kudzu bug, sugarcane aphid, rice stink bug and several moth species. Research on kudzu bug and sugarcane aphid assessed the spread of these pests throughout the state, tested insecticides, and developed action thresholds. We examined the extent that neonicotinoid insecticides negatively affect honeybees. We developed treatment options and recommendations to manage pastures infested by fall armyworm.

Refine and deliver methods to manage crop and animal pests, with applied research projects.

    Impacts
    What was accomplished under these goals? We addressed new and recurring pest management challenges that crop and animal growers in Arkansas must face. The outcome of our applied entomological research was greater understanding of crop pests and their dynamics, and recommendations for growers to implement to manage pests of field crops and cattle. These recommendations were made to optimize use of multiple tactics and minimize negative environmental impacts. We conducted applied field research projects designed to manage crop pests such as rice stink bug, alfalfa plant leafhopper, grape colaspis, and the species of Lepidoptera found on cotton. A recently detected pest, the yellow sugarcane aphid, has expanded throughout the state and appears to be using johnsongrass as a resource for early season. The aphid produces honeydew, which makes harvest difficult and causes economic losses for growers. Trials to assess aphid densities and test insecticide treatments were continued. Work also continues to develop an action threshold. The project to develop treatment options and recommendations to manage pastures infested by fall armyworm continued, though fewer flare-ups of armyworm occurred this past year.

      Outputs
      Target Audience: Agricultural growers (animal and crop), crop consultants, Extension faculty Changes/Problems: Nothing Reported What opportunities for training and professional development has the project provided? Field days and scout schools demonstrated research results to growers, crop consultants and crop scouts. How have the results been disseminated to communities of interest? Crop scout schools, IPM demonstrations, field days and county-level education meetings provided research results and recommendations to more than 6,500 individuals. What do you plan to do during the next reporting period to accomplish the goals? Continue to develop methods to sample yellow sugarcane aphid on sorghum, to develop appropriate control methods that minimize economic loss and environmental harm. Refine and deliver methods to manage crop and animal pests, with applied research projects.

      Impacts
      What was accomplished under these goals? We addressed new and recurring pest management challenges that crop and animal growers in Arkansas must face. The outcome of our applied entomological research was greater understanding of crop pests and their dynamics, and recommendations for growers to implement to manage pests of field crops and cattle. These recommendations were made to optimize use of multiple tactics and minimize negative environmental impacts. We conducted applied field research projects designed to manage crop pests such as rice stink bug, alfalfa plant leafhopper, grape colaspis, and the lepidopteran complex on cotton. A new pest to Arkansas, the yellow sugarcane aphid, was found infesting sorghum, producing sufficient honeydew to make harvest difficult, causing potential economic losses for growers. Trials to assess aphid densities and test insecticide treatments were conducted to provide recommendations to growers, thus reducing aphid numbers and alowing growers to harvest their crop. We also began to develop an action threshold, a research project which will continue in 2015. Pheromone traps were used throughout the corn-growing region of eastern Arkansas to detect corn borers, in order to help determine when or whether treatments were warranted. The project to develop treatment options and recommendations to manage fall armyworm in pasture continued, though there were fewer locations with flare-ups of armyworm this past year.
