本试验用乐果、辛硫磷、杀灭菊酯、氯氰菊酯、好年冬、辟蚜雾和鱼藤精等7种常用杀虫剂对广东5个市县的菜缢管蚜进行毒力测定。试验结果说明不同用药水平地区的蚜虫种群抗药性有差异。并筛选出3种较高效杀虫剂。
In this study, seven kinds of commonly used insecticides such as dimethoate, phoxim, fenvalerate, cypermethrin, perennial winter, hatching aphids and rotenone were tested for their virulence . The test results show that there are differences in the resistance of aphid populations in different drug levels. Three kinds of more efficient insecticides were screened out.
