不同杀虫剂对红花指管蚜的室内毒力测定及田间药效试验

Toxicity Measurement and Field Trial Test on the Effects of Different Pesticides on Uroleucon gobonis

以6种杀虫剂为供试药剂,以红花指管蚜为供试虫源,采用室内毒力测定与田间试验相结合的方法,进行了6种杀虫剂对防治红花指管蚜室内毒力测定与田间筛选试验。结果表明:室内毒力测定6种杀虫剂,其浓度与死亡率存在高度的正相关;由室内毒力测定与田间药效试验结果综合分析,在防治红花指管蚜时优先选用10%吡虫啉可湿性粉剂、4%阿维·啶虫脒乳油、1.8%阿维·高氯乳油,可以有效控制红花指管蚜的发生。

Taking 6 kinds of pesticides as test drug,with Uroleucon gobonis as test pest,using the combination method of toxicity measurement and field trial combined method, 6 kinds of pesticides to prevent Uroleucon gobonis were tested. The results showed that toxicity measurement the density of 6 kinds of pesticides existed a high positive correlation with the mortality rate;by comprehensive analysis of toxicity measurement and field trial, 10% Irnidacloprid WP, 4% Abamectin- Acetamiprid EC and 1.8% Abamectin · Cypermethrin EC to prevent Uroleucon gobonis were preferred, they could effectively control of Uroleucon gobonis.
