Abstract

Field experiments were conducted at Aga district, Dakahlia Governorate during 2011 and 2012 cotton seasons to study the effect of five pesticides; Methomyl, Profenofos, Cholorpyrifos, Deltamethrin, Lambada-Cyhalothrin and insect growth regulator (IGR), Chlorfluazuron; against eggs and  larvae  of Helicoverpa armigera and infested cotton buds. Results showed that in case of H. armigera eggs Chlorpyrifos caused the highest reduction percentage of in egg of bollworm (72.03%), followed by Deltamethrin 69.29% , Profenofos 68.93%, Lambada-Cyhalothrin 67.29% and Methomyl 65.98%, while the least reduction was 62.44% for Chlorfluazuron. In case of the larvae, the results showed Chlorpyrifos caused the highest reduction 79.58% followed by Chlorfluazuron 73.29%, Profenofos 72.54%, Deltamethrin 64.22% , Lambada-Cyhalothrin 58.40%. While the lowest reduction percentage was 56.68% for Methomyl. In case of the infested cotton buds, Chlorpyrifos caused the highest reduction with 75.54%, followed by Chlorfluazuron 72.05%, Profenofos 70.47%, Deltamethrin 57.18% and Lambada-Cyhalothrin 57.06%, while the lowest reduction was 48.54% for Methomyl.  Generally Chlorpyrifos was most effective on the eggs and larvae of H. armigera and the infested cotton buds, while Chlorfluazuron was the least affective on H. armigera eggs, but Methomyl was the least effective on the larvae of H. armigera and infested buds.
