摘要：

摘 要: 采用蜡蚧轮枝菌(Verticillium lecanii) MZ041024菌株不同分生孢子浓度对平菇厉眼蕈蚊的幼虫和蛹进行毒力测定。结果表明，MZ041024菌株杀虫活性较高，对幼虫和蛹最高校正死亡率分别为91.79%和88.94%，LC50分别达到1.745×105个/ml和4.723×105个/ml；LT50最短分别为3.51d和3.78d 。

Abstract:

Abstract : It was determined the virulence of Verticillium lecanii MZ041024 on Larvae and pupae of Lycoriella pleuroti. The bioassay results indicated that insecticidal activity of ethyl acetate was higher than that of others, their mortality rate of larvae and pupae respectively were 91.79% and 88.94%, with LC50 values of 1.745×105 spores /ml and 4.723×105 spores /ml ; LT50 was respectively3.51d and 3.78d, against Larvae and pupae of Lycoriella pleuroti , respectively.
