    广东褐飞虱种群对4种杀虫剂的抗药性

    Resistance of Nilaparvata lugens (Stål) populations to four types of insecticides in Guangdong Province

      摘要
    • 摘要:
      目的  测定广东省褐飞虱Nilaparvata lugens (Stål)对常用杀虫剂的抗药性，为科学防治水稻褐飞虱提供依据。
      方法  在室内采用稻苗浸渍法测定了采自广东省广州市、雷州市、连州市、南雄市、海丰县、大埔县和怀集县等7个地方田间褐飞虱种群对噻嗪酮、吡虫啉、噻虫嗪和吡蚜酮的抗药性。
      结果  广东褐飞虱种群对吡虫啉抗性仍处于极高水平抗性阶段(161.9~3576.4倍)，对噻嗪酮抗性仍处于高水平至极高水平抗性阶段(93.4~1497.8倍)，对噻虫嗪抗性仍处于高水平至极高水平抗性阶段(61.0~517.8倍)，对吡蚜酮抗性处于敏感性下降至中等水平抗性阶段(3.7~11.0倍)。
      结论  在水稻上防治稻飞虱需暂停使用吡虫啉、噻嗪酮和噻虫嗪；减少吡蚜酮在褐飞虱防治中的使用次数，以延缓抗药性的产生。

       

      Abstract:
      Objective  To determine resistance of brown planthopper, Nilaparvata lugens (Stål), to common insecticides in Guangdong Province, so as to provide a basis for controlling N. lugens.
      Method  N. lugens were collected from Guangzhou, Leizhou, Liangzhou, Nanxiong, Haifeng, Dapu and Huaiji of Guangdong Province. The resistance of N. lugens to buprofezin, imidacloprid, thiamethoxam and pymetrozine were determined by dipping rice seedlings in laboratory.
      Result  N. lugens populations in Guangdong were extremely highly resistant to imidacloprid with the resistance ratios from 161.9 to 3 576.4, highly to extremely highly resistant to buprofezin with the resistance ratios from 93.4 to 1 497.8, and to thiamethoxam with the resistance ratios from 61.0 to 517.8, and less sensitive to pymetrozine with a medium level of resistance ratios from 3.7 to 11.0.
      Conclusion  Imidacloprid, bprofezin and thiamethoxam should be suspended, and pymetrozine should be restricted to use on rice, so as to slow down the insecticide resistance and properly control N. lugens.
