Abstract: The resources and pathogenicity of entomogenous fungi in Lishan National Nature Reserve in the southern east of Shanxi Province were studied.Fungi of 19 species of 13 genera of 3 orders were isolated and identificated and 2 new taxa were peculiar to Shanxi Province. Among them, fungi of Hyphomycetales were dominant. The pathogenicity test of Beauveria amorpha and Verticillium indicum to larvaes of Cerura menciana and Parnops glasunowi were tested. The average pathogenical effect of Beauveria amorpha can be increased by 16 4% higher than that of Verticillium indicum.
