摘　　要：采用叶片浸渍法测定了2015-2019年湖北赤壁、武穴、武汉、孝感、黄冈,湖南长沙,江西南昌、萍乡,安徽合肥和河南信阳共10个地区稻纵卷叶螟田间种群对毒死蜱、茚虫威、乙基多杀菌素、阿维菌素、氯虫苯甲酰胺、溴氰虫酰胺和氟苯虫酰胺7种杀虫剂的敏感性,并对数据进行聚类分析和回归分析。结果显示,(1)稻纵卷叶螟田间种群对7种杀虫剂敏感性差异明显,杀虫剂的毒力次序为氟苯虫酰胺≥阿维菌素≥乙基多杀菌素>氯虫苯甲酰胺≥茚虫威>溴氰虫酰胺>毒死蜱;(2)不同地区稻纵卷叶螟种群对杀虫剂的敏感性差异不明显;(3)不同年份之间差异显著。一些种群对毒死蜱、氯虫苯甲酰胺、茚虫威和溴氰虫酰胺的敏感性年度间存在明显差异。如赤壁和长沙种群对毒死蜱的敏感性从2015年至2016年下降了2.3~4.1倍;赤壁、孝感、长沙和合肥种群对毒死蜱的敏感性从2016年至2019年上升了2.1~4.9倍;赤壁、武穴和孝感种群对氯虫苯甲酰胺的敏感性从2015年至2019年下降了2.6~7.3倍;武穴种群对茚虫威的敏感性从2015年至2018年下降了4.2~4.7倍;武穴和长沙种群对溴氰虫酰胺的敏感性从2015年至2018年抗性下降了2.2~6.7倍。以上结果表明,目前华中地区稻纵卷叶螟田间种群对氯虫苯甲酰胺等的敏感性下降趋势很明显,因此对氯虫苯甲酰胺等的抗性治理显得非常重要,目前田间稻纵卷叶螟防治优先推荐阿维菌素、乙基多杀菌素和溴氰虫酰胺等交替轮换使用。Continuous monitoring of the field population susceptibility to insecticides is an important measure to control Cnaphalocrocis medinalis.The present study aimed to detect the susceptibility of the C.medinalis field populations to common insecticides in Hubei,Hunan,Jiangxi,Anhui and Henan provinces.Leaf-dipping method was used to detect the susceptibility of the C.medinalis field population to seven insecticides in Chibi,Wuxue,Wuhan,Xiaogan,Huanggan,Changsha,Nanchang,Pingxiang,Hefei and Xinyang during 2015-2019.In addition,cluster and regression analysis were performed on the detected data.The results showed that:(1)The toxicities among seven insecticides were significant different,with an order of fluorobenzamide≥abamectin≥spinetoram>chlorantraniliprole≥indoxacarb>cyantraniliprole>chlorpyrifos.(2)No significant difference of the susceptibility was detected among different populations of C.medinalis.(3)There were significant differences between the years.Significant changes of sensitivity in different years were found among some populations to chlorpyrifos,chlorantraniliprole,indoxacarb and cyantraniliprole.For example,the susceptibility of Chibi and Changsha populations of C.medinalis to chlorpyrifos decreased by 2.3-4.1 times from 2015 to 2016,and that of Chibi,Xiaogan and Changsha populations increased 2.1-4.9 times from 2016 to 2019,the susceptibility of Chibi,Wuxue and Xiaogan populations to chlorantraniliprole decreased 2.6-7.3 times from 2015 to 2019,the susceptibility of Wuxue population to indoxacarb decreased by 4.2-4.7 times from 2015 to 2018,and the susceptibility of Wuxue and Changsha population to cyantraniliprole decreased by 2.2-6.7 times from 2015 to 2018.The above results indicated that the susceptibilities of the C.medinalis field populations to chlorantraniliprole and other insecticides in central China are decreasing significantly,so that the resistance management for these insecticides is very important currently.Abamectin,spinetoram and cyantraniliprole are preferentially recommended f
