Entomopathogenic fungi isolated from pine caterpillars, as biological control agents were evaluated against the 5th instar larvae of silkworms, bombyx mori. The body weights of silkworm larvae were reduced by entomopathogenic fungi. Virulence of the spores isolated from the insects was more stronger than that of the spores isolated from media. LD$_{50}$ value of the pathogen was 6,464${\times}$10$^3$spores/ml. Entomopathogenic fungi, Beauveria, isolated from dead pine caterpillars was possible agents for use in microbiological control.l.
