小菜蛾抗药性研究及其治理

小菜蛾是一种世界性十字花科蔬菜害虫，巳报道小菜蛾对50多种杀虫剂产生抗药性，包括有机氯、有机磷、氨基甲酸酯、拟除虫菊酯类、昆虫生长调节剂及苏云金杆菌（Bt）类等杀虫剂。本全面阐述了国内外小菜蛾抗药性研究概况，包括小菜蛾抗性发展、交互抗性、抗性稳定性、抗性机理及抗性遗传等方面的研究，并对小菜蛾抗药性的治理策略进行讨论。

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.
