１９９４－１９９５年用浸虫法测定６种杀虫剂对广西南宁、永福稻纵卷叶螟三龄幼虫的毒力，南宁虫群对杀虫双的敏感性最低，对溴氰菊酯的敏感性最高，６种杀虫剂的敏感性顺序依次为：溴氰菊酯＞喹硫磷＞三唑磷＞甲胺磷＞氧化乐果＞杀虫双；永福虫群对氧化乐果的敏感性最低，对溴氰菊酯的敏感性最高，６种杀虫剂的敏感性顺序依次为：溴氰菊酯＞喹硫磷＞三唑磷＞甲胺磷＞杀虫双＞氧化乐果。两地虫群对同一种杀虫剂的敏感性有一定差异。
In 1994-1995, the toxicity of 6 kinds of insecticides to third-instar larvae of C. medinalis in Nanning of Guangxi and Yongfu was determined by the method of soaking insects. The sensitivity of Nanning population to insecticidal double was the lowest, and it was sensitive to deltamethrin The highest susceptibilities of the six pesticides were as follows: deltamethrin> quetiapine> triazophos> methamidophos> omethoate> insecticidal double; the susceptibility of Yong flies to omethoate The lowest, the highest sensitivity to deltamethrin, six insecticides in the order of sensitivity: deltamethrin> quetiapine> triazophos> methamidophos> insecticidal double> omethoate. Insecticide susceptibility of the same insecticide between the two groups have some differences.
