摘要:

为筛选防治草地贪夜蛾的高效安全药剂,本研究以草地贪夜蛾幼虫为试验对象,采用浸渍法测定了5种杀虫剂对草地贪夜蛾的室内毒力,并进行田间防效试验。室内毒力试验结果表明,5种供试杀虫剂对草地贪夜蛾均有不同程度的毒杀作用,其LC50值的大小顺序为:5%甲维盐ME<60 g/L乙基多杀菌素SC<10%虫螨腈SC<40%辛硫磷EC<90%敌百虫SP。田间防效试验结果表明,5种供试杀虫剂都对草地贪夜蛾幼虫有很好的防治效果,60 g/L乙基多杀菌素SC、10%虫螨腈SC和40%辛硫磷EC在72 h后防效均可达到100%,5%甲维盐ME和90%敌百虫SP在72 h后防效达到90%以上。因此,这5种杀虫剂可作为防治草地贪夜蛾的有效药剂。

Abstract:

In order to select effective and safe insecticides for controlling Spodoptera frugiperda, larvae of S. frugiperda were used as experimental materials in this study. The indoor toxicity of five insecticides was determined by impregnation method, and field control tests were conducted. The results of indoor toxicity test showed that the five insecticides had different indoor toxicities to the third instar larvae of S. frugiperda, and their LC50 values from low to high were: 5% emamectin benzoate ME<60 g/L spinetoram SC<10% chlorfenapyr SC<40% phoxim EC<90% dipterex SP. The results of field control efficacy test showed that all the five insecticides had good control effects on the larvae of S. frugiperda. The control efficacies of 60 g/L spinetoram SC, 10% chlorfenapyr SC and 40% phoxim EC were 100% at 72 hours after the treatment, and the control efficacies of 5% emamectin benzoate ME and 90% dipterex SP were more than 90% at 72 hours after the treatment. Therefore, these five insecticides can be used as effective agents to control S. frugiperda.
