Abstract
Caged Aedes aegypti were exposed to a range of concentrations of d-phenothrin, d-allethrin and tetramethrin in a wind tunnel. Mortality, blood engorgement and egg production among these mosquitoes and their progeny were recorded. Tetramethrin was the most effective (LC50 of 0.0017%), followed by d-phenothrine (LC50 0.0031%) and d-allethrin (LC50 0.01%). Blood engorgement was decreased by treatment with each pyrethroid at the high concentration (0.002%, 0.003% and 0.01% respectively). Treatment with d-phenothrin or d-allethrin decreased egg production, but tetramethrin increased oviposition. These effects had ceased in the F2.
