褐飞虱抗药性研究现状

褐飞虱Nilaparvata lugens(Stal)对杀虫剂产生抗药性是其近年来暴发频繁的重要原因。文章综述国内外关于褐飞虱抗药性的研究成果,包括褐飞虱抗性测定方法、抗药性的发展、交互抗性、抗性遗传、抗性机理及抗性治理等。田间褐飞虱种群对新烟碱类药剂产生不同程度的抗药性,其中对吡虫啉产生高水平到极高水平抗性,对氯噻啉和噻虫嗪分别产生中等水平和低水平的抗药性,对呋虫胺和烯啶虫胺仍然处于敏感性阶段。此外,褐飞虱种群对噻嗪酮(昆虫生长调节剂)产生低水平到中等水平抗性。长期大面积使用化学药剂是褐飞虱产生抗药性的重要原因。因此,必须加强褐飞虱的抗性治理,以延缓其抗药性进一步发展。

Current status of insecticide resistance in the brown planthopper, Nilaparvata lugens

In recent years, insecticide resistance might be associated with frequent occurrence of the brown planthopper, Nilaparvata lugens （Stal）, in China. The advance and achievements at home and abroad in the research of insecticide resistance of N. lugens were reviewed in this paper, which includes the bioassay method, insecticide resistance development, cross-resistance, resistance inheritance, resistance mechanism and resistance management, etc. Field populations of N. lugens have developed variable resistance to neonicotinoids, with a high or extremely high resistance level to imidacloprid, a low and medium resistance level to imidaclothiz and thiamethoxam, respectively, and no resistance to dinotefuran and nitenpyram. Further examination indicated that some field populations had evolved a low or medium resistance level to buprofezin, an insect growth regulator. Long-term use of chemical insecticides in a wide range of rice-growing areas is the important reason for resistance of N. lugens to insecticides. Therefore, insecticides resistance management strategies must be developed to prevent further increase in resistance of N. lugens.
