中文摘要：
采用稻茎浸渍法监测湖北省武穴、天门、监利、通城、孝感、公安及枣阳七地褐飞虱Nilaparvata lugens (Sta1)田间种群对吡虫啉、噻嗪酮、氟虫腈的抗药性。结果表明：2006、2007和2008年3年7地褐飞虱种群对吡虫啉的抗性分别为98.89～389.19倍、69.00～153.33倍和56.32～116.89倍，达高水平至极高水平抗性，但3年期间总体抗性水平呈现一定程度的下降趋势；2007和2008年2年7地褐飞虱对噻嗪酮的抗性分别为13.39～41.06倍和6.94～20.44倍，达低水平至高水平抗性；2007和2008年2年7地褐飞虱对氟虫腈抗性分别为0.97～2.64倍和0.63～1.42倍，为敏感阶段。此外，还对褐飞虱的治理进行讨论。
英文摘要： tRice stem dipping method was used to monitor the susceptibility of Nilaparvata lugens (Sta1) to imidacloprid from 2006 to 2008 and to buprofezin and fipronil from 2007 to 2008 in 7 field populations collected in Wuxue, Tianmen, Jianli, Tongcheng, Xiaogan, Gong'an, and Zaoyang of Hubei province. The results showed that the collected population produced resistance to imidacloprid with resistance index varied from 98.89 to 389.19, 69.00 to 153.33, and 56.32 to 116.89 respectively compared with the susceptible colony from year 2006 to 2008 although the resistance level decreased in three years, while the resistance to buprofezin with resistance index from 13.39 to 41.06 in 2007 and 6.94 to 20.44 in 2008 And the susceptible to fipronil with resistance index varied from 0.97 to 2.64 in 2007 and 0.63 to 1.42 in 2008. The strategy of resistance management of N. lugens was also proposed.
