The U.S. Department of Agriculture (USDA) and the U.S. Department of Defense (DOD) have joined forces to create effective barriers and gear that help shield deployed soldiers from disease-causing insects.
Scientists at the Agricultural Research Service (ARS) Center for Medical, Agricultural and Veterinary Entomology (CMAVE) in Gainesville, Fla., are evaluating insecticides, testing pesticide application equipment, and treating military tents, camouflage screening and sun awnings with long-lasting residual pesticides. The research is a component of a USDA-DOD initiative called the Deployed War-Fighter Protection Research Program. ARS is USDA's principal intramural scientific research agency.
Biting insects and arthropods can transmit pathogens that cause devastating diseases such as malaria, dengue fever, yellow fever and Japanese encephalitis (spread by mosquitoes), or leishmaniasis (spread by sand flies infected with Leishmania parasites). Such illnesses are a particular problem for susceptible U.S. troops deployed to countries where these diseases are common.
Entomologist Seth Britch, who works in CMAVE's Mosquito and Fly Research Unit and is also a captain in the U.S. Army Reserve, found that camouflage netting treated with a specially formulated insecticide effectively reduces mosquito populations and provides long-lasting protection for military personnel. Desert-pattern netting material was sprayed, allowed to dry, packed and shipped to Tallil Air Force Base in Iraq, where it was stored for five months, tested and then shipped back to CMAVE for analysis. Almost 300 days after it had been treated, the material was still successful in controlling mosquitoes. Treated netting also provided protection against sand flies and filth flies.
