Figure 2. Anopheles gambiae sensu lato mortality rates associated with various insecticides and study sites, western Kenya. A) Mortality rates associated with pyrethroid insecticides deltamethrin, permethrin, and lambdacyhalothrin. In Chulaimbo, permethrin was not tested because of a lack of mosquitoes. B) Mortality rates associated with DDT (organochlorine), bendiocarb (carbamate), and malathion (organophosphate). The susceptible Kisumu strain at Kenya Medical Research Institute was used as a control. Error bars indicate 95% CIs.
