Project Number: 6615-32000-045-13-T
Project Type: Trust
Start Date: May 1, 2010
End Date: Sep 30, 2013
Evaluate the ability of insecticide-treated materials to kill mosquitoes indoors over extended periods of time. In Phase II will determine the bioefficacy of treated Durable Lining (DL) in huts in which the walls are partially covered.
Insecticide-treated wall linings will be placed on the inner walls of small, wooden huts. Bioassay tests will be conducted in these huts with three genera of laboratory-reared mosquitoes on a weekly basis. Some wall linings will be subjected to simulated weathering conditions before being tested. In Phase II the same five huts located on CMAVE property that were used in Phase I of the project will be used. Three huts will remain covered as they were in Phase I; two completely covered with untreated DL and one completely covered with treated DL. Two additional huts will be utilized in which only half the wall space will be covered with treated DL. In one the top half will be covered and in the other the bottom half will be covered. Bioefficacy of these configurations will be determined in the same manner as outlined in Phase I: WHO cone tests and release of free flying mosquitoes of three species of colony reared insects. One modification will be that WHO cone tests will be conducted on both the covered and uncovered wall surfaces. Both bioassay techniques will be conducted on a monthly basis.
