摘要
噻虫嗪是一种新型的高效新烟碱类杀虫剂,对同翅目(蚜虫、粉虱、飞虱等刺吸式口器害虫)、部分鞘翅目(马铃薯甲虫)和鳞翅目害虫及其对其他种类药剂产生抗性的害虫种群具有优异的防效。化学药剂的大量不合理使用是导致害虫产生抗药性的主要原因。本文简要综述了害虫对噻虫嗪的抗性发展概况、交互抗性、抗性机理及抗性治理策略。马铃薯甲虫和烟粉虱种群对吡虫啉和噻虫嗪都表现出交互抗性,然而,褐飞虱种群对吡虫啉和噻虫嗪却没有交互抗性。害虫的抗性治理应包括抗性监测、抗性机理研究、合理使用杀虫剂及实行综合治理等。
Thiamethoxam is a member of the neonicotinyl class of insecticides that has high activity against Homoptera（sucking insects such as aphids, whiteflies, planthoppers） and some Coleoptera（Colorado potato beetles） and Lepidoptera, including some species with a long history of resistance to earlier-used other kinds insecticides. The massive abuse of chemical insecticides is main reason leading to the development of insecticide resistance of pest. This article summarized the incidence of resistance, cross-resistance, resistance mechanism and resistance management strategies of posts to thiamethoxam. Cross-resistance to imidacloprid and thiamethoxam were found in the Colorado potato beetle and the tobacco whitefly populations. However, there was no cross-resistance between imidacloprid and thiamethoxam in the brown planthopper population. Insecticide resistance management should include effective resistance monitoring programs, resistance mechanism researchs, making rational use of insecticides and carrying out integrated pest management and so on.
