摘要
为筛选防治核桃举肢蛾效果较好的杀虫剂,本试验选用毒死蜱、乙酰甲胺磷和杀灭菊酯3种杀虫剂对核桃举肢蛾进行试验。试验结果表明,试验选用的3种杀虫剂不同剂量处理对核桃举肢蛾均有一定的防治效果。其中,40%乙酰甲胺磷乳油以1000倍液处理对核桃举肢蛾表现出了最高的防效,为92.11%;48%毒死蜱乳油以1000倍液处理对核桃举肢蛾的防效次之,为85.35%;20%杀灭菊酯乳油以1500倍液处理的防治效果最低,为76.27%。3种试验药剂中40%乙酰甲胺磷乳油和48%毒死蜱乳油以1000倍液处理对核桃举肢蛾的防效较好,可以在生产中推广应用。
The control effects of three pesticides, Chlorpyrifos, Acephate and Fenvalerate canopy spraying, on Atrijuglans hetaohei were experimented. The results showed that their control effects are different. Acephate of 40% diluted 1000 times had the highest control effect of 92.11%; that of Chlorpyrifos of 48% diluted 1000 times was the second with 85.35%, and that of Fenvalerate of 20% diluted 1500 times was the worst with 76.27%. The control efficacies of Chlorpyrifos of 40% and Acephate of 48% were the best, and they could be popularized in the production.
