Cross-resistance pattern in cypermethrin resistant Amsacta albistriga (Lepidoptera: Arctiidae) to various classes of insecticides

Cross resistance to insecticides has become a major problem in insecticide resistant insects. This has threatened the safe implementation of integrated pest management programme. To prevent development of cross resistance, a choice of suitable alternative insecticide should be made in the resistance population. In the present study, we have investigated the cross resistance pattern of several insecticides in cypermethrin resistant Amsacta albistriga (CypRes). The CypRes strain show high cross-resistance to permethrin, deltamethrin (58.1 and 70.2-fold) followed by dichlorvos, monocrotophos and profenofos (50.0, 47.01 and 27.3-fold), but moderate cross resistance to imidacloprid (3.8) and very low cross resistance to emamectin and NeemAzal insecticides (1.1 and 2.4-fold) respectively. This study provides important information for understanding cross-resistance pattern and facilitating a better strategy for the management of pyrethroid resistance in A. albistriga.
