2.5%鱼藤酮乳油防治黄守瓜药效研究

Research on Effect of 2.5% Rotenone EC Against Aulaeophora femoralis chinensis wesise

常德地区蔬菜生产中对黄守瓜认识和防控不够重视,在防治上比较传统,加上其受惊后即飞离逃逸或假死,耐饥能力很强,防控难度加大,并表现出对化学杀虫剂的抗药性,危害不断加剧。使用2.5%鱼藤酮乳油对黄守瓜进行了室内毒力测试和室外药效对比试验,结果表明:2.5%鱼藤酮乳油600倍液防治黄守瓜效果显著,它属于低毒、环保、高效、不产生抗药性的植物源杀虫剂,适宜在常德地区推广使用。

A ulaeophora femoralis chinensis wesise did not attach enough importance to the understanding and the prevention and controiling in the vegetables production in Changde region,and its prevention and controiling was more traditional.h flied away from the escape or feign death after frightening, hunger resistance ability very strong, difficulties of prevention and control increased, and it showed the resistance of chemical pesticides, its harm is also increasing.We targeted the use of 2.5% rotenone EC on keeping Aulaeophora femoralis chinensis wesise indoor toxicity test and outdoor efficacy experiment.The results showed that the effect of 2.5% rotenone EC 600 times liquid against Aulaeophora femoralis chinensis wesise was remarkable.It was low toxicity,environmental protection,high efficiency and no resistance of botanical pesticides.It was suitable to use in Changde region.
