Advances in studies on the insecticide resistance of Plutella xylostella (L.) and its management

It is recently reported that field populations of Plutella xylostella, a cosmopolitan insect pest of crucifers, has shown resistance to more than 50 insecticides including organochlorines insecticides, organophosphorus insecticides, carbamate insecticides, pyrethroid insecticides, insect growth regulators and Bacillus thuringiensis. In this paper, advances in the studies on insecticide resistance in Plutella xylostella are reviewed including the development of resistance, cross resistance, stability of resistance, resistance mechanism and resistance inheritance. Counter measures for resistance management are discussed.
