摘要: 【目的】明确目前褐飞虱Nilaparvata lugens田间种群对常用防治药剂的抗性现状,为制定褐飞虱的科学用药策略提供科学依据。【方法】于2009-2014年采用稻茎浸渍法监测了湖北褐飞虱武穴梅川、枣阳十里铺、孝感陈店、鄂州长港和武汉江夏稻田的褐飞虱田间种群对11种杀虫剂的敏感性。【结果】湖北稻区褐飞虱田间种群已对吡虫啉(抗性倍数RR=101.8~1 239.4)、噻嗪酮(RR=15.9~1 326.3)产生高水平抗性;对噻虫嗪(RR=24.9~146.5)产生中等水平至高水平抗性;对噻虫胺(RR=9.9~16.5)、呋虫胺(RR=13.5~15.9)、乙虫腈(RR=18.3~60.4)、毒死蜱(RR=17.4~29.8)、异丙威(RR=13.9~46.0)产生中等水平抗性;对啶虫脒(RR=5.1~9.9)产生低水平抗性;对噻虫啉(RR=3.9~7.1)处于敏感至低水平抗性水平;对醚菊酯(RR=1.3~4.9)处于敏感水平。此外,褐飞虱对噻虫嗪、噻嗪酮抗性上升明显,同时褐飞虱对吡虫啉抗性也有上升的趋势。【结论】仍需暂停吡虫啉、噻嗪酮在水稻上防治稻飞虱,严格限制吡蚜酮在水稻上的使用次数;醚菊酯可作为吡虫啉、噻嗪酮和吡蚜酮的替代药剂或轮换药剂。

Abstract: 【Aim】 The brown planthopper, Nilaparvata lugens, occurs in many parts of Asia and has developed a high degree of resistance to several chemical classes of common insecticides. The objective of this study is to assess the current status of insecticide resistance in field populations of N. lugens, so as to supply effective insecticide resistance management strategies to prevent or delay the development of insecticide resistance in N. lugens. 【Methods】 The susceptibility of the field populations of N. lugens from rice fields of Zaoyang City, Xiaogan City, Wuxue City, Wuhan City, and Ezhou City in Hubei Province to 11 insecticides was assayed by rice stem dipping method. 【Results】 The field populations of N. lugens have developed high-level resistance to imidacloprid [the resistance ratio (RR)=101.8-1 239.4)] and buprofezin (RR=15.9-1 326.3), medium- to high-level resistance to thiamethoxam (RR=24.9-146.5), medium-level resistance to clothidianidin (RR=9.9-16.5), dinotefuran (RR=13.5-15.9), ethiprole (RR=18.3-60.4), chlorpyrifos (RR=17.4-29.8) and isoprocarb (RR=13.9-46.0), low-level resistance to acetamiprid (RR=5.1-9.9), no resistance (susceptible) or low-level resistance to thiacloprid (RR=3.9-7.1), and no resistance (susceptible) to etofenprox (RR=1.3-4.9). 【Conclusion】 It is suggested that imidacloprid and buprofezin should still be suspended for the control of N. lugens and the application frequencies of pymetrozine must be limited. Etofenprox, however, could be an alternate or rotational insecticide for them.
