应用6种杀虫剂对栎线小卷蛾幼虫进行室内毒力测定,结果表明:供试杀虫剂对该虫的毒力大小依次为:1.8%阿维菌素乳油、3%高渗苯氧威乳油、20%啶虫咪可溶性粉、20%甲维.丙溴磷乳油、20%氯.辛乳油、10%吡虫啉可湿性粉剂。从中筛选出4种,开展了田间防治试验。试验结果表明:施药48h后,1.8%阿维菌素乳油0.05%、0.033%药液,20%甲维.丙溴磷乳油0.5%药液、20%啶虫咪可溶性粉0.1%药液防治效果均达96%以上。
The results showed that the virulence of the tested insecticides on the insects was 1.8% abamectin EC, 3% hypertonic benzene 10% imidacloprid soluble powder, 20% methylvalachlor, emulsifiable concentrate 20% chlorine, octoxin emulsifiable concentrate, 10% imidacloprid wettable powder. Four species were screened out and field control trials were conducted. The results showed that after 48h, 1.8% avermectin 0.05%, 0.033%, 20% methylvalachlor EC 0.5% and 20% pyridine 0.1% The effect reached more than 96%.
