云杉腮扁叶蜂药剂防治试验

Tests of Pesticide Control on Cephalcia abietis

本文应用化学药剂对云杉腮扁叶蜂进行了防治试验。结果表明:利用1.2%烟碱·苦参碱乳油300倍液防治云杉腮扁叶蜂成虫,防治效果为28.57%;利用25%灭幼脲Ⅲ号悬浮剂1000倍液的防治效果为62.24%;利用4.5%高效氯氰菊酯微乳剂1000倍液防治效果达82.65%;利用弥雾机按高效氯氰菊酯、柴油、水的体积比为1∶2∶7喷洒药液,防治效果达97.45%。

In this paper,an experimental study was carried out on the control of Cephalcia abietis by pesticide.The results showed that the control effect of 300 times solution of 1.2%nicotine·matrine was 28.57%,the control effect of 1000 times solution of 25%diflubenzuronⅢwas 62.24%,the control effect of 1000 times solution of 4.5%beta-cypermethrin microemulsion was 82.65%.The mist sprayer was used to spray the liquid medicine according to the volume ratio of beta-cypermethrin,diesel oil and water at 1∶2∶7,and the control effect reached 97.45%.
