球孢白僵菌对浙江双栉蝠蛾幼虫的致病力研究
A Study of the Virulence of Beauveria bassiana Strains against Bipectilus zhejiangensis Wang Larvae
摘要
Abstract
8 strains of B. bassiana were used to test for pathogenicity against B. zhejiangensis larvae. The results indicated that the strain B3 had higher pathogenicity. After inoculating strain B3 with (1.0±0.5)× 106 conidia mL for 12 days, the correct mortality and the cadaver rate of larvae were (90.71±2. 16)% and (87.07±0.95)% respectively, and its median lethal time (LT50) was the shortest (6.20 days). The average conidia individual of cadaver was significantly higher with 5.75×1010 conidia per larva. The stronger lethal time of the strain B3 against larvae was the 6th day to 8th day. The median lethal concentration (LC50) of the 5th and 6th day to larvae were determined at 1.35×108 conidia perlarva and 1. 23×106 conidia perlarva respectively. It suggests that the strain B3 has great development application value, and strain B187 has certain application potential.关键词
