为了明确目前褐飞虱对常用药剂的抗性现状，以便制定防治褐飞虱的科学用药策略，于2010-2011年间，在室内采用稻茎浸渍法监测了我国主要稻区19个褐飞虱种群对五种常用杀虫剂的抗性。结果表明，2010年全部监测种群对噻嗪酮均处于中等水平抗性（RR为11.3~23.4倍），2011年除广西桂林、江西上高2个褐飞虱种群为中等水平抗性（15.3~19.7倍）外， 其他80%监测种群均已达高水平抗性（40.7~119.7倍），抗性明显上升；两年19个褐飞虱监测种群对吡虫啉均为高到极高水平抗性（82.3~1935.8倍），与20062009年相比，吡虫啉抗性有再次升高趋势；2010年褐飞虱对噻虫嗪的抗性为低到中等水平抗性（6.1~14.4倍），2011年除广西桂林种群为低水平抗性外，其他8个种群均为中到高水平抗性（12.8~62.3倍），较前一年明显上升；两年18个监测种群对毒死蜱均处于敏感到低水平抗性阶段；对吡蚜酮的抗性2010年7个监测种群为敏感低水平抗性（1.9~5.1倍），2011年全部褐飞虱监测种群均已达中等水平抗性（15.7~25.4倍），暗示随着吡蚜酮的大量广泛使用，褐飞虱对其抗性较高，需要引起生产上的密切关注。为科学治理水稻褐飞虱，应严格执行无交互抗性的杀虫剂间的合理轮用或混用。
To lay a foundation for nationwide resistance management of the brown planthopper Nilaparvata lugens（Stl）, we collected 19 samples of the planthopper from 13 locations covering eight provinces to monitor the resistance to five conventional insecticides in 2010 and 2011.The results showed that the resistance of the brown planthopper to buprofezin increased obviously given all populations were at middle resistance level (11.3 to 23.4 fold) in 2010 and 80% populations were at high resistance level (40.7 to 119.7 fold) in 2011. All the monitored populations still remained to be high to extremely high resistant to imidacloprid (82.3 to 1935.8 fold), the resistance increased obviously again comparing with the period from 2006 to 2009. To thiamethoxam, the resistance ratios were between 6.1 to 14.4 fold and 12.8 to 62.3 fold in 2010 and 2011, respectively; and the resistance increased significantly in most areas in the two years. All the 18 populations remained to be susceptible to low resistant to chlopyrifos. The resistance risk to pymetrozine may be a little high since the monitored samples were susceptible or developed low level resistance (1.9 to 51 fold) in 2010, while the resistance increased to moderate level (15.7 to 25.4 fold) in the next year. It indicated that the resistance to pymetrozine might increased quickly with the wide use of this insecticide in the main rice planting areas. The scientific rotation and mixing among the insecticides without cross resistance must be adopt.
