一株虫生真菌的鉴定及其对杉肤小蠹的致病力
Identification of Entomopathogenous Fungus and Pathogenicity Test of Phloeosinus sinensis Adult
摘要
Abstract
In 2023,a strain of entomopathogenic fungus BFZ-103 was isolated from the infected larva of Cerambycidae sp.in Zhang-pu County.To clarify the taxonomic status of strain BFZ-103,by combining morphological and molecular biological evidence to iden-tify the entomopathogenic fungus.We observed and recorded the entomopathogenic fungus biological characteristics and determined its pathogenicity to adult Phloeosinus sinensis.The results indicate that strain BFZ-103 was identified as Beauveria brongniartii.The strain cultured with CDA had a higher growth rate at 25 ℃,after 15 days of cultivation,the colony diameter was(72.36±0.67)mm.The spore production of strain BFZ-103 was(9.63±1.24)× 106spore·cm-2 15 days after culture on SDAY at 25 ℃.The Beauveria brongniartii strain BFZ-103 showed high virulence to the adult of Phloeosinus sinensis.The mortality of the adult of M.alternatus reached 80.9％15 days after inoculation.In summary,the strain BFZ-103 has the good potential to be developed as biocontrol agents for Phloeosinus sinensis.关键词
