中文摘要: 2009年采用稻茎浸渍法测定广东省惠州地区褐飞虱Nilaparvata lugens(Stal)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。
英文摘要: The susceptibility of the brown planthopper (BPH ), Nilaparvata lugens (Stal) to imidaeloprid,buprofezin, isoprocarb, butylene-fipronil , nitenpyram and chlorpyrifos,was monitored using the rice-stem dipping method in Huizhou, 2009. The results indicate that local BPH populations have strong resistance to imidacloprid (resistance ratio of 422.2-fold), medium resistance to buprofezin and isoprocarb (resistance ratios of 11.0-14.0-fold, respectively), low resistance to butylene -fipronil (3.7-fold) and were still susceptible to nitenpyram and chlorpyrifos (resistance ratio <3-fold). The rational use of insecticides for N. lugens management is discussed in light of these results.
