Abstract: An experiment was conducted to evaluate the efficacy of different insecticides against wheat aphid and impact on their natural enemies’ lady bird beetle and syrphid fly. Three different pesticides (Imidacloprid, Thiamethoxam and Tubaonazole) with different concentrations used to check the efficacy against wheat aphid and their impact on syrphid fly larvae and lady bird beetle adult, larvae both. Actara showed less aphid population but also affected predators population. Results revealed that among these three insecticides (imidacloprid, thiamethoxam and tubaconazole + imidacloprid) thiamethoxam showed very effective against wheat aphid. This also toxic to lady bird beetle and syrphid fly as compared to remaining other two insecticides. So judicious use of insecticides is very necessary. Those insecticides used which are highly effective against wheat aphid and least toxic to their predators.
