This study evaluates the effects of some insecticides on the survival of larvae of Apis mellifera L. The pyrethroids (fenvalerate and λ-cyhalothrin) caused maximum mortality at highest concentration (12.5 ppm), when compared to quinalphos and thiamethoxam. Fenvalerate was observed to be extremely toxic in its maximum concentration, as none among 1-2 days old treated larvae (after multiple exposures) survived after 24 hours (i.e., after 4th exposure. Lavae were observed to be tolerant to thiamethoxam as 66.67% survival was observed till emergence under similar conditions.
