云杉幼树落叶松球蚜瘿蚜防治试验初报

摘要

Adelgs laricis gall aphid control experiment was carried through 4 kinds of agentia.The result showed that the control effect of 40%omethoate EC1 000 times was worse relatively.The average insecticidal effect of 10% imidacloprid WP1 000 times, 25%thiamethoxam WG3 000 times and 3%acetamiprid EC1 500 times were more than 90%.It was not easy to appear cross resistance for insects.%通过4种不同药剂对落叶松球蚜瘿蚜进行防治试验，结果表明：40％氧化乐果EC1000倍液防治效果相对较差；而10％吡虫啉WP1000倍液、25％噻虫嗪WG3000倍液、3％定虫脒EC1500倍液平均杀虫效果均能达到90％以上，且不易使害虫对其产生交互抗性。
