ABSTRACT
The mosquito Aedes aegypti is a serious public health concern since it is the principle vector of several arboviruses. Insecticide application is the most essential component of the present global strategy for the control of mosquito-associated diseases, and vector control is a critical component of that strategy. However, the present study was conducted to evaluate the toxicity of five different insecticides (Spinosad 100%EC, chlorfenapyr 36%SC, pyriproxyfen 10% EC, matrine 0.5 AS and imidacloprid 70% WDG) against Aedes aegypti larval mortality under laboratory conditions. Result indicated that Spinosad (77.32% mortality) and pyriproxyfen (66.28% mortality) are more toxic to A. aegypti larvae as compared to matrine, chlorfenapyr and imidacloprid after 72-h exposure. While minimum mortality was recorded after 24-h exposure of insecticides in all treatments. So, it can be concluded that spinosad was more toxic to kill A. aegypti larvae.
