不同球孢白僵菌菌株生物学特性与其对家蚕致病力的关系
Relationship between Biological Characteristics of Beauveria bassiana ( Bals.) Vuill and Pathogenicity to Bombyx mori L.
摘要
Abstract
[Objective] This study was to investigate the relationship between biological characteristics of Beauveria bassiana ( Bals. ) Yuill and pathogenicity of Bombyx mori L. , with the aim to provide scientific basis for the control of white muscardine in Bombyx mori L. . [ Method ] The strains isolated and purified from the 6 Beauveria bassiana biocontrol agents from all over the country and the 3 white muscardine silkworms collected from Guangxi provincial silkworm rearing areas were identified by the morphological observation and molecular biology technology. The pathogenicity of silkworms to B. bassaina was determined, and the biological characteristics such as growth diameter, spore production amount and the extracellular protease activity of the different B. bassiana strains were compared. [ Result] The isolated 9 strains were al] B. bassaina (Bals. ) Vuillemin, and all strains had high pathogenicity to silkworm, but with different pathogenicities. The growth diameter, spore production amount and extracellular protease activity of different B. bassiana strains were also different, and showed correlation with the patheogenicity to silkworms. [Conclusion] B. bassiana spores production amount and exocellular protease activity had significant positive correlation with their pathogenicity to silkworm.关键词
