2011 Annual Report
1)sprayers and methods used to make adult and barrier treatments in military settings; and.
2)the current methodology/protocols used to evaluate the efficacy of field-applied sprays. In FY 2011, eight unique sprayers were evaluated for spray droplet size. Each was tested using generic spray solutions across the full operational ranges of spray pressure, nozzle setting, and flow rate. The data from these tests are being incorporated into a smartphone application that will be made available to the user communities. Using aircraft provided by the U.S. Air Force, Youngstown, OH, field trials were conducted in conjunction with personnel of the U.S. Navy Entomology Center of Excellence, Jacksonville, FL, and ARS scientists at Gainesville, FL. These studies focused on measuring spray movement and insect mortality in an open field and within vegetative canopies. 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.
