<br/><br/> The toxic effects of six non-conventional insecticides belong to different chemistries in comparison with one conventional insecticide were laboratory studied on newly hatched larvae of American bollworm (ABW), Helicoverpa armigera (Hübner) and pink bollworm Pectinophora gossypilla.The results showed that  methoxyfenozide, emamectin-benzoate and spinosad were the most effective insecticides against newly hatched larvae of ABW .Emamectin-benzoate and spinosad were most effective insecticides against newly hatched larvae of PBW. LC₅₀ treatment of emamectin-benzoate had a deleterious effect on the development . Field evaluation of tested insecticides at season 2013 on cotton revealed that, emamectin-benzoate and spinosad were more efficient in controlling pink bollworm and spiny bollworm .Moreover,a field trial on tomato plants was carried out to evaluate their efficacy against ABW. Results revealed that chlorantraniliprole, emamectin-benzoate and spinosad  were more efficient in controlling the American bollworm population than pyridaly, chlorpyrifos and indoxacarb
