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。
In order to select the best insecticide for the prevention and treatment of Ligusticum wallichii, three insecticides, chlorpyrifos, acephate and fenpropathrin, were selected to test the Ligustrum lucidum. Test results show that the three pesticides tested selected different doses of walnut Liugong moths have some control effect. Among them, 40% acephate EC with 1000 times liquid showed the highest control effect on the walnut moth, which was 92.11%; 48% chlorpyrifos EC , 85.35%. The control effect of 20% fenvalerate EC with 1500 times solution was the lowest, which was 76.27%. The control efficacy of 40% acephate EC and 48% chlorpyrifos EC in the three kinds of test chemicals was better than that of the control.
