内蒙古农业大学草地昆虫研究中心科研人员采用点滴法,于室内测定了阿维菌素、茚虫威和鱼藤酮等3种杀虫剂单独使用及与绿僵菌混用对沙葱萤叶甲3龄幼虫的协同致死作用,以期为协调使用化学药剂和生防制剂防治沙葱萤叶甲提供参考。3种杀虫剂单独使用时的毒力测定结果表明,阿维菌素对沙葱萤叶甲3龄幼虫的毒力最强,LD50值为4.80ng/头,其次是茚虫威和鱼藤酮,
Inner Mongolia Agricultural University Grassland Insect Research Center researchers to use the drop method to determine the indoor abamectin, indoxacarb and rotenone and other three kinds of insecticides alone and mixed with Metarhizium anisopliae third instar larvae Synergistic lethal effect, with a view to coordinating the use of chemical agents and biological control agents to provide a reference for the prevention and control of Diabrotica. The results of the virulence tests of the three insecticides alone showed that abamectin had the strongest virulence to the third-instar larvae of D. trifoliata, LD50 was 4.80ng / head, followed by indoxacarb and rotenone,
