摘要
室内用浸渍法测定了 14种杀虫剂对山东泰安和浙江杭州两地小菜蛾种群的毒力。结果表明 ,两地小菜蛾对溴氰菊酯产生了高水平抗性 ,分别达 6 3.9和 52 .5倍 ;对氟啶脲的抗性也分别达 35.0和 12 2 .1倍 ;常用的有机磷类、灭多威和杀虫双等药剂对它们的毒力均较低 ;两个小菜蛾种群对阿维菌素和氟虫腈最敏感。
Two populations of Plutella xylostella were collected from Taian of Shangdong province (TA Population) and Hangzhou of Zhejiang province (HZ Population). The toxicity of 14 insecticides to the two populations were tested by dipping method in laboratory. The results showed that the resistance ratios of TA Population and HZ Population to deltamethrin were 63.9 and 52.5 folds, to chlorfluazuron were 35.0 and 122.1 folds, respectively. The toxicity of abamectin and fipronil were higher, but that of the tested organophosphorus insecticides and methomyl, etc. to the populations were lower.
