Ecological diversity of entomogenous fungi in Luyashan,Pangquangou and Manghe national nature reserves of Shanxi were documented continuously from 1996 to 2001. 276 fungal strains were isolated from 469 specimens. 124 strains of entomogenous fungi were preliminarily identified to the generic level by characteristics of fruiting body, vegetative cells and spores. In total, 25 species (including varieties and forms) belonging to 10 genera were recognized, showing high diversity and high endemicity. Entomogenous fungi from Manghe National Nature Reserve are in a dominant position in terms of strains, genera and species. Statistical comparisions of the main entomogenous fungi from different sites, elevation and habitats show that distribution and diversity of the entomogenous fungi are influenced by many environmental factors, such as climate and vegetation. These strains have apparently vertical distribution bands and micro habitat distribution characteristics. Almost all species and 66% of the strains were isolated from a medium elevation range (1000~2000 m). Entomogenous fungal species in mixed forest, deciduous broad leaved forest and scrub near river were more plentiful and well distributed than those in other habitats, especially mixed forest. These results have important implications for exploitation and utilization of entomogenous fungal resources.
