This study was conducted to investigate agents inducing conidial germination of an entomopathogenic fungus, Beauveria bassiana KK5. Different chemicals including carbohydrates were mixed with conidia of B. bassiana and incubated on water agar for 12 hours. Fructose, mannose and skim milk were useful for spore germination compared to other chemicals. Bioassays against green peach aphids were conducted with the fungal conidia suspended in 1% fructose, mannose and skim milk. Of them, a mixture of skim milk plus conidia of B. bassiana KK5 showed the highest mortalities against 3 rd instar of green peach aphid.
