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 arthopods responsible for carrying disease agent. 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. 3.Progress Report: This is a new project being conducted under the DoD Deployed Warfighter Protection Program. It is a sister project to the expired 6202-22000-028-12R and is continuing and expanding upon the work of that project. The goal of this project is to evaluate the effectiveness of:. 1)sprayers and methods used to make treatments for vector pest control in military settings; and. 2)the current methodology/protocols used to evaluate the efficacy of field-applied sprays. In FY 2012, a new USDA-ARS wind tunnel facility that is compliant with World Health Organization testing protocols was constructed. This new facility will be used to evaluate the spray characteristics of commonly used pesticides with and without a tracer added to the mixture. The facility will enable tracking of sprays that have been generated by spray equipment, and that drift through a mosquito-infested test area. Work by this project, as it continues, will develop improved technologies and protocols for military applications of pesticides in order to better protect U.S. WarFighters from pest and disease-transmitting arthropods.
