用点滴法测定稻纵卷叶螟５龄幼虫对杀虫双等４种杀虫剂的触杀毒力反应及抗药性，结果表明，以甲胺磷的毒性最高，其余依次为巴丹、乙酰甲胺磷和杀虫双。在抗药性测定中，除了个别地区对杀虫双有低水平的抗性、相对毒力指数为１３．８９外，广东不同地区稻纵卷叶螟对杀虫双等４种杀虫剂的抗药性发展是缓慢的，相对毒力指数均在４．０６以下。
The contact toxicity and drug resistance of the 5th instar larvae of rice leaf roller were studied by using the drip method. The results showed that the toxicity of methamidophos was the highest, followed by that of Bata and acetylacetonate Amine phosphorus and insecticidal double. In the drug resistance test, in addition to individual areas have low levels of insecticide resistance, the relative virulence index of 13.89, different parts of Guangdong rice leaf roller on insecticidal double four kinds of insecticide resistance The development of the drug is slow, relative toxicity index below 4.06.
