摘　　要：2006-2009年,用稻茎浸渍法连续监测了广西南宁市、广东阳江市、湖南东安县、福建福清市、江西上高县、湖北孝感市、浙江金华市、江苏通州市和安徽和县共9个地区褐飞虱种群对吡虫啉、噻嗪酮和氟虫腈的抗性变化。结果表明:褐飞虱种群对吡虫啉的抗性仍处于高水平至极高水平抗性阶段(105.5～459.7倍),但2009年监测到东安、孝感、上高种群对吡虫啉的抗性已有下降趋势;褐飞虱种群对氟虫腈的抗性有增长趋势,2006到2009年褐飞虱种群对氟虫腈由敏感至低水平抗性(<6.9倍)发展到了中水平至高水平抗性(13.5～43.3倍);由于2005年吡虫啉在高抗地区的禁用,褐飞虱种群对噻嗪酮的抗性上升速度加快,2009年已处于低水平至中水平抗性阶段(7.0～14.4倍)。这表明在吡虫啉、氟虫腈被禁用后,大面积单一使用噻嗪酮进行防治,褐飞虱对噻嗪酮的抗性有可能加速发展。Resistance of Nilaparvata lugens（Stl） to imidacloprid,buprofezin,fipronil was monitored using rice stem dipping method in 9 different regions,including Nanning,Yangjiang,Dong＇an,Fuqing,Shanggao,Xiaogan,Jinhua,Tongzhou,Hexian from the year of 2006 to 2009.The results indicated that most of populations developed high level of resistance to imidacloprid（resistance ratios are 105.5-to 459.7-fold）,but the data collected in 2009 revealed that populations from Dong＇an,Xiaogan,Shanggao showed slightly decreasing resistance to imidacloprid,and increasing resistance to fipronil.During 2006-2009 populations of N.lugens changed their resistance to buprofezin from being susceptible or low level（resistance ratios are below 6.9-fold） to moderate or high level（resistance ratios are 13.5-to 43.3-fold）.Because imidacloprid was prohibited in highly resistant regions beginning from 2005,N.lugens increased its resistance to buprofezin rapidly,and it was already at low or moderate level（the resistance ratios are 7.0-to 14.4-fold） in 2009.As a result,after imidacloprid and fipronil were prohibited,using buprofezin singly to control N.lugens in large areas will lead to resistance rapidly.
