稻纵卷叶螟是我国水稻生产上威胁较大的害虫。目前用以防治稻纵卷叶螟的常用农药对硫磷、甲胺磷等对人畜的毒性较大,杀虫脒、杀虫双等对蚕桑生产影响严重。针对这一问题,1985年,我们选用不同毒级的有机磷农药进行了田间筛选试验,通过试验,明确了低毒性的乙酰甲胺磷对稻纵卷叶螟有显著的防治效果。在此基础上,还进行了乙酰甲胺磷杀虫性能、使用技术等方面的试验研究。
Rice leafroller is a threat to China’s rice production pests. Currently used to control the rice leafroller common pesticides parathion, methamidophos and other toxic to humans and animals, chlordimeform, insecticidal double Serious impact on sericulture production. In response to this problem, in 1985, we selected different poisonous levels of organophosphate pesticides for field screening tests. Through experiments, we found that the low toxicity of acephate has a significant control effect on C. medinalis. On this basis, we also carried out experimental research on insecticidal properties of acephate, the use of technology and so on.
