The Physiologic Response of Moroccan Locust to Common Pesticides in North of Golestan Province

The present study was carried out under a complete randomised block design with 3 replications in one of the pastures of Chapar Quimeh village, under Gonbad-e-Kavous district. The pesticides used in this research are included, malathion 57% EC at the rate of 500 and 1000 cc per hactare, deltamethrin 2.5% EC at the rate of 200 and 500 cc per hactare and lambda cyhalothrin 23% EC at the rate of 100, 150 and 200 cc per hactare. The results showed that the highest reduction of pest population was obtained due to use of lambda cyhalothrin 200 and 150 cc per hactare and the least reduction by the application of malathion 500 cc per hactare. According to the highest reduction of Moroccan locust that was obtained in application of lambda cyhalothrin treatment it can be conluded that this pesticide is suggestible in Gonbad-e-Kavous district and malathion pesticide due to the least reduction of pest, is not suggestible in this region.
