A laboratory study was carried out to assess the residual toxicity of certain insecticides to egg parasitoids of Spodoptera frugiperda (J E Smith), Trichogramma chilonis Ishii, T. pretiosum Riley (Hymenoptera: Trichogrammatidae), and Telenomus remus Nixon (Hymenoptera: Scelioniadae). The median lethal concentrations were recorded at 24 and 48 hr after exposure period to adults of egg parasitoids to nine insecticides. Among the tested spinetoram was found to be “dangerous”, however, chlorantraniliprole, chlorantraniliprole + lambdacyhalothrin, chlorpyriphos + cypermethrin, indoxacarb, cyantraniliprole, emamectin benzoate, thiamethoxam + lambdacyhalothrin and azadirachtin were found to be “slightly to moderately toxic” to T. chilonis and T. pretiosum. Chlorantraniliprole, emamectin benzoate, indoxacarb and spinetoram were found to be “dangerous”, however, chlorpyriphos + cypermethrin, thiamethoxam + lambdacyhalothrin, chlorantraniliprole + lambdacyhalothrin, cyantraniliprole and azadirachtin were “slightly to moderately toxic” to T. remus.
