Summary:
Growers in the southeastern United States plant one-fourth (~2.6 million acres) of the US cotton crop, with an annual farm gate value exceeding $800 million. Recent changes in production and advances in pest management have allowed these growers to decrease insecticide applications from >15 to approximately 3 per year. Stink bugs, which are highly mobile and utilize many different hosts, are thriving and causing economic damage in this new production environment. Due to insecticide resistance issues and limited information on basic stink bug biology, growers have few treatment options except blanketing entire fields with organophosphate insecticides. Our project is designed to develop an understanding of pest ecology so we can utilize cultural controls and formulate novel management strategies. This approach will minimize adverse environmental effects of insecticides, improve biological control, and reduce the development of insecticide resistance. Specific objectives are: 1) investigate weekly changes in stink bug population density and reproductive status within a farmscape, and 2) determine whether stink bug populations and damage in cotton can be managed by spraying alternating strips, as opposed to the entire field. All proposed objectives will be completed by the end of the project. The experiments will be conducted in grower-owned farmscapes (wheat, corn, cotton, peanuts, and soybeans) replicated in Georgia, North Carolina, and South Carolina. This proposal is relevant to the priorities of the SR-IPM program because it will increase IPM knowledge, is a partnership among states, and includes integrated approaches. Results will be widely disseminated.
