摘    要:为了调查浙江省水稻飞虱抗药性现状,采用稻茎浸渍法测定了2010—2011年采自浙江省嘉兴市褐飞虱田间种群、杭州市白背飞虱种群以及长兴市和嘉兴市灰飞虱种群对几种常用杀虫剂的敏感性。测定结果表明,嘉兴种群褐飞虱对吡虫啉分别产生了615.9~814.2倍抗性,对噻虫嗪产生了66.2倍抗性,对噻嗪酮具有13.0倍抗性,对烯啶虫胺尚敏感;相对于2008年种群,2010年杭州白背飞虱种群对毒死蜱的敏感性降低了9.5倍,说明白背飞虱对毒死蜱的抗性上升很快;相对于2007年种群,2010—2011年长兴灰飞虱对噻虫嗪、毒死蜱和吡虫啉的敏感性分别降低了1.6,2.5和2.3倍;噻虫嗪和毒死蜱对长兴种群灰飞虱的毒力略高于嘉兴种群。根据敏感性测定结果,提出了针对防治水稻飞虱的田间用药和抗药性治理的参考意见。

Abstract:To investigate the current status of the resistance to insecticides of rice planthoppers in Zhejiang province,rice stem-dipping method was used for detecting the susceptibilities to insecticides of brown planthopper,Nilaparvata lugens(Stl),collected from Jiaxing city,and white-backed planthopper,Sogatella furcifera(Horvth),collected from Hangzhou city,and small brown planthopper,Laodelphax striatellus(Fallén),collected from Jiaxing city and Changxing city.The results showed that the Jiaxing population of N.lugens had developed a high level of resistance to imidacloprid with 615.9-814.2 fold,and to thiamethoxam with 66.2 fold,and to buprofezin with 13.0 fold,and still susceptible to nitenpyram.The susceptibility of the Hangzhou population of S.furcifera to chlorpyrifos was dropped 9.5 times from 2008 to 2010,which suggested a rapid evolution of resistance of S.furcifera to chlorpyrifos.The susceptibilities of the Changxing population of L.striatellus to thiamethoxam,chlorpyrifos and imidacloprid were reduced 1.6,2.5 and 2.3 fold,respectively,from 2007 to 2010 or 2011,and toxicities of thiamethoxam and chlorpyrifos against the Changxing population of L.striatellus were slightly higher than those against the Jiaxing population.Based on the bioassay data,strategies of the application of insecticide in field and insecticide resistance management for the control of rice planthoppers were also proposed.
Keywords:brown planthopper  white-backed planthopper  small brown planthopper  susceptibility  resistance
