几种杀虫剂对葡萄斑叶蝉的毒力和田间药效试验
Toxicity and Flied Control Efficiency of Several Pesticides on Erythroneura Apicalis Nawa.
摘要
Abstract
[Objecfive] The different insecticides in Xinjiang were studied to provide scientific basis for the chemical control of Erythroneura apicalis Nawa. [Method ] The toxicity of two pesticides to 3rd instar lawae of Erythroneura apicalis Nawa were determined in room by leaf - dip method . Sevreral insecticides were tested in field . [ Result] The results showed that imidacloprid and thiamethoxam had higher activities , their LC50 were 46 . 26 μg/ mL,19.31 μg/mL respectively. The results of field trial indicated that all of four insecticides including 10％ WP imidacloprid , 25 ％ WG thiamethoxam, 25％ pymetrozine WP and 99％ mineral oil had better control effects on Erythroneura apicalis Nawa, and 10％ WP imidacloprid , 25％ WC thiamethoxam had longer persistence against the insect, their controlling efficiency were 100 ％ after 7 days . [ Conclusion]Based on the results of toxicity tests and field trials, 25 ％ pymetrozine WP and 99％ mineral oil could be recommended for controlling Erythroneura apicalis Nawa .关键词
