枣实蝇药剂防治试验初报

Preliminary Report on Control Test of Carpomya vesuviana Costa

经室内外药效对比试验,筛选出对枣实蝇幼虫和蛹防效较好的药剂。试验结果表明,供试药剂中对蛹土壤处理效果好的药剂是20%辛硫.灭多威乳油和48%毒死蜱乳油,其室内药效达到了95%以上。5%吡虫啉乳油、11.1%顺式氯氰菊酯乳油、2.5%功力乳油对蛹的药效较差。田间树冠喷雾防治幼虫药效好的药剂是5%吡虫啉乳油,药效达到92.37%。48%毒死蜱乳油、20%辛硫.灭多威乳油、11.1%顺式氯氰菊酯乳油对幼虫的药效较差。

This research was conducted to examine the protection effect of the pesticides on controlling Carpornya vesuviana Costa. Based on a comparison experiment between indoor and outdoor pesticides effects,several pesticides were tested to control Carpomya vesuviana Costa, and then lhe best one against Carpomya vesuviana Costa larva and pupa was selected. The results of lhe trial showed that insecticides including 20% phoxim methomyl EC and 48% chlorpyrifos EC against pupa were cffeclive, and their in door effect was above 95%. And insecticides including 5% imidacloprid EC, 1 1. 1% alphacyperm ethrin EC and 2.5% gongfu EC against pupa were not very effective. The spray insecticides including 5%0 imidacloprid EC against larvae on tree crowns were very effective in field, their effect was close to 92.37%. The insecticides including 48% chlorpyrifos EC,20% phoxim methomyl EC and 11.1 % alphacyperm ethrin EC against larvae were relatively poor.
