摘  要:
室内毒力测定结果表明 ,溴虫腈对甜菜夜蛾幼虫的毒力随着龄期的增加而减弱 ,对 1~ 2龄期幼虫的毒力最高 ,3龄后敏感性降低。田间试验结果显示 ,溴虫腈对甜菜夜蛾有优异的防治效果 ,用 5 %溴虫腈EC 80ml/ 6 6 7m2 ,防治效果 95 %以上 ,持效期 2 0天

摘  要:
The result of laboratory testing showed that the toxicity of chlorfenapyr to S exigua deduced with the increase of instar Larva in 1~2 instar was the most sensitive The toxicity to larva in 3 instar decreased obviously In the field, the control efficiency was over 95% and residual activity lasted 20 days as this 5% chlorfenapyr EC was 80ml/667m 2
