Evaluation of certain insecticides on nettings for their efficacy and wash resistance against mosquito species.
Five insecticides (Bifenthrin, Deltamethrin, Etofenprox, Permethrin and Lamda cyhalothrin) recommended by WHO, at their recommended dose were compared for their efficacy and wash resistance through bioassay against mosquito vectors, Culex quinquefasciatus, Aedes aegypti and Anopheles stephensi. Etofenprox treated nettings exhibited better knockdown and mortality than the other insecticides. The order of efficacy of the insecticides treated nettings was Etofenprox > or = Deltamethrin > Lambda cyhalothrin > Permethrin > Bifenthrin.
