| 摘 要： | 作者分析了褐飞虱对噻嗪酮、甲胺磷的代谢抗药性。室内生物测定显示褐飞虱对甲胺磷的抗性与虫体酯酶活力升高有关，而对噻嗪酮的抗性则主要是由于多功能氧化酶活力的提高。褐飞虱的个体酯酶活力测定表明，甲胺磷抗性群体中的酶活力中等以上的个体频率明显增加，达２６．０８％，比对照种群提高１４．６５％；噻嗪酮抗性群体显示相似趋势，但酶活力中等以上的个体频率增幅较小，为２０．７４％，比对照提高９．３１％。说明褐飞虱对这

| Abstract: | The metabolic resistance of the brown planthopper, Nilaparvata lugens, to buprofezin and metamidophos was investigated in this article. Bioassay data revealed that the enhanced activity of aliesterase was the main factor responsible for the metabolic resistance to metamidophos, and the increase of the mixed-function oxidase activity was one of the major mechanisms of the metabolic resistance to buprofezin. The results of the aliesterase activity test showed the frequency of individuals with high and medium activity was 26. 08% in the metamidophos-selected group, increased by 14. 65% as compared with the non-selected group, and a rather slight increase by 9. 31% in the bupro-fezin-selected group. |
