2011 Annual Report
The World Health Organization cone bioassay touch test was used to evaluate mosquito knockdown and mortality caused by the insecticide-treated durable wall lining against 3 mosquito species. A second test method, which utilized 100 free-flying female mosquitoes of each species, was also used. During the first 9 months of the study, 100% mortality was observed with the cone test and there was approximately 90 percent mortality among the free-flying mosquitoes released in the huts. Both of these results reflected the capability of the treated wall lining to kill mosquitoes over a 9-month period. Since this project began, ARS staff met with Vestergaard-Frandsen personnel to review these results and discuss ongoing research at the Annual Meeting of the American Society of Tropical Medicine and Hygiene in Atlanta, GA and at the ARS Center for Medical, Agricultural and Veterinary Entomology in Gainesville, FL. Progress was monitored through meetings, telephone calls, and e-mails.
