摘  要:
用蜡蚧轮枝菌MZ041024菌株对菜缢管蚜进行室内毒力测定。研究结果表明,该菌株对菜缢管蚜具有较高的致病率。孢子浓度2.4×105个/ml造成大量菜缢管蚜感染致死,其LT50为(6.26±0.35)d;高浓度2.4×108个/ml对菜缢管蚜感染致死LT50为(3.72±0.19)d。MZ041024菌株与其他蜡蚧轮枝菌菌株相比有较强的致病力。

摘  要:
The virulence of Verticillium lecanii Viegas MZ041024 against Lipaphis erysimi(Kaltenbach) was bioassayed in laboratory.The results showed that there was still a LT50 of(6.26±0.35)d in a concentration of 2.4×105 conidia/ml and a high concentratim of 2.4×108 conidia/ml yielded LT50 of(3.72±0.19)d for Lipaphis erysimii(Kaltenbach).Then,compared with other results,the Verticillium lecanii Viegas MZ041024 had a higher virulence.
