2009年采用稻茎浸渍法测定广东省惠州地区褐飞虱Nilaparvata lugens(Stl)种群对吡虫啉、噻嗪酮、异丙威、丁烯氟虫腈、烯定虫胺和毒死蜱等杀虫剂的敏感性,测定结果表明:当地褐飞虱种群对吡虫啉产生了极高水平抗性(抗性倍数为422.2倍),对噻嗪酮、异丙威产生了中等水平抗性(抗性倍数分别为11.0和14.0倍),对丁烯氟虫腈仍处于敏感性降低(抗性倍数为3.7倍),对烯定虫胺和毒死蜱敏感(抗性倍数<3倍)。基于褐飞虱对这6种药剂抗性的明显差异,对田间治理褐飞虱合理使用药剂进行了讨论。 In 2009, the susceptibility of imidacloprid, buprofezin, isoprocarb, fipronil, buprofen, chlorpyrifos and other insecticides to Nilaparvata lugens (Stl) population of the brown planthopper, Nilaparvata lugens, The results showed that the local population of BPH had a very high level of resistance to imidacloprid (resistance multiple of 422.2 folds) and moderate level of resistance to buprofezin and isoprocarb (resistance multiples of 11.0 and 14.0, respectively Fold), the sensitivity to butylene-fipronil is still reduced (3.7 fold) and to olechin and chlorpyrifos (<3 fold). Based on the obvious difference of resistance of Nilaparvata lugens to these six agents, the rational use of Nilaparvata lugens in field management was discussed.
