2008年保定市首次发现美国白蛾入侵危害，美国白蛾危害日趋严重，防治美国白蛾刻不容缓。本试验通过调查其主要危害的树种确定其寄主范围，室内测定几种作用机制不同化学药剂对美国白蛾致死率，为今后治理检疫美国白蛾提供理论依据。试验结果表明：苏云金杆菌和菊酯类药剂防治效果最好，致死率100％；活体生物类农药中，阿维菌素对美国白蛾的防治药效较差，5000倍液第二天致死率仅为45％；生物代谢产物苦参碱，有较好的开发利用前途，致死率100％，但幼虫死亡时间长；有机磷药物药效也较好。

In 2008 ,Hlyphantria cunea was firstly discovered in Baoding City and seriously harm forest plant .Therefore ,the prevention of Hlyphantria cunea is a urgent task .The study surveyed Hlyphantria cunea host range ,tested lethality of some kinds of chemical a-gent to the pest in lab .The results showed bacillus thuringiensis pesticide and the chrysan-themum ester insecticide were the best with 100% lethality rate .Abamectin was lower ,with 45% lethality of 5 000X of abamectin .Biological metabolite matrine had the best ppesticide effect ,with 100% lethality rate ,but larve died sowly .The efficacy of organophosphorus pesticide was good ,but it harmed environment .
