摘要

为明确陕西关中地区麦蚜田间种群对杀虫剂的抗药性现状,采用浸叶法测定了兴平、礼泉、凤翔、岐山、扶风地区麦田禾谷缢管蚜种群对高效氯氰菊酯、溴氰菊酯、吡虫啉、异丙威、毒死蜱、阿维菌素、氟啶虫胺腈等7种杀虫剂的抗性水平。结果表明,禾谷缢管蚜对高效氯氰菊酯的抗性水平最高,其中凤翔种群对高效氯氰菊酯达到高水平抗性(抗性倍数为72.5),岐山和扶风种群对该药产生中等水平抗性(抗性倍数分别为31.4、29.9);5个地区的禾谷缢管蚜对溴氰菊酯、吡虫啉、毒死蜱、异丙威和阿维菌素的抗性水平较低,表现为敏感、敏感性下降或者低抗性;5个地区的试虫对氟啶虫胺腈均表现为敏感。分析认为,高效氯氰菊酯不适合用于关中地区禾谷缢管蚜防治,氟啶虫胺腈作为一种新型杀虫剂,可以在该虫防治中推广使用,吡虫啉、阿维菌素等其他几种杀虫剂可以在禾谷缢管蚜的防治中交替使用。
        To investigate the resistance levels of Rhopalosiphum padi to seven different insecticides, we collected five populations of R.padi from five regions(Xingping, Liquan, Fengxiang, Qishan and Fufeng) in Guanzhong area of Shaanxi province. Resistance levels of the samples to seven insecticides(beta-cypermethrin, deltamethrin, imidacloprid, isoprocarb, chlorpyrifos, abamectin and sulfoxaflor) were tested by leaf dipping methods. The results showed that R.padi from different regions varied in the resistance to the tested insecticides. Five field populations showed highest resistant level to beta-cypermethrin in comparison with that to other insecticides. Population from Fengxiang showed highest resistant(RR=72.5) level to beta-cypermethrin, while populations from Qishan and Fufeng showed moderate resistant(RR=31.4 and 29.9, respectively) level to this insecticide. R.padi from the five regions showed susceptible, minor resistant or low resistance to deltamethrin, imidacloprid, chlorpyrifos, isoprocarb and abamectin. All the populations were susceptible to sulfoxaflor. We conclude that beta-cypermethrin cannot be used in the field for R.padi control. Sulfoxaflor can be recommended as a novel insecticide to control the aphid. Imidacloprid, abamectin and other tested insecticides can be used in rotation to avoid the resistance development of R.padi to insecticides.
