中文摘要：试验采用蝉拟青霉(Paecilomyces cicadae)孢子粉处理小菜蛾Plutella xylostella L.幼虫，结果表明，蝉拟青霉可以在小菜蛾幼虫和蛹上寄生，并导致小菜蛾死亡。室内试验，蝉拟青霉对小菜蛾的致死率高达96.55%；田间试验，1.6×107个/mL浓度的022017#蝉拟青霉防治
英文摘要：Treating the larva of Plutella xylostella (L.) with the spores of Paecilomyces cicadae can parasitize the larvae and pupae of P.xylostella and cause them death. The highest death rate was 96.55% in laboratory. We got 75.86% death rate
