2012 Annual Report
1a.Objectives (from AD-416):
To devise innovative methods for the suppression of insects that transmit diseases to U.S. military deployed abroad.
1b.Approach (from AD-416):
Identify and test compounds with insecticidal activity that makes them especially beneficial in the rapid control of mosquitoes, flies, and other arthropods responsible for carrying disease agents. Devise innovative means of applying control agents especially suited for use in combat or deployment conditions. Identify and test new classes of topical and area repellents for use by troops.
This project is related to Objective 2 of the in-house project - "Develop new application methods for pesticides to biting Nematocera that minimize environmental exposure and that optimize lethal or repellent effect, including presentation on clothing, aerosol application in or outdoors, residual application, disinsection of aircraft, and delivery of spatially repellent compounds."
Research continued to be conducted to identify new compounds that were toxic to mosquitoes, identify new repellents and other personal protection tools against mosquitoes and biting flies, and develop new and improved methods for applying toxicants. This research was conducted in close collaboration with active duty military personnel in the continental U.S. and internationally. Examples of research conducted under this project include: studies of residual barrier treatments on native vegetation and artificial substrates in desert, tropical, and sub-tropical habitats for control of mosquitoes and sand flies; bite protection evaluation of permethrin-treated military uniforms; studies on pesticide-induced gene expression and identification of crucial proteins; insecticide-treated targets for house fly exclusion; laboratory comparison of attraction-inhibitors against Phlebotomus papatasi sand flies; and reduction of host-seeking responses of mosquitoes by sub-lethal pesticide exposure.
Progress was monitored with meetings and discussions with the ARS National Leader for Program 104, Deployed War Fighter Protection (DWFP) Research Program committee members, and associated Department of Defense (DoD) personnel who visited the Center for Medical, Agricultural, and Veterinary Entomology or at other venues. These interactions included multiple presentations at the Annual Review of the DWFP Research Program in Beltsville, MD (November 2011) and at annual meetings of the Society for Vector Ecology in Flagstaff, AZ (September 2011), the Florida Mosquito Control Association Jacksonville, FL (November 2011), the Entomological Society of America in Reno, NV (November 2011), the American Society of Tropical Medicine and Hygiene in Philadelphia, PA (December 2011), and the American Mosquito Control Association in Austin, TX (February 2012), as well as at periodic meetings of the Armed Forces Pest Management Board in Silver Spring, MD.
