This study was carried out to investigate pathogenicity of cordyceps on the silkworm larva, Bombyx mori. For experiment, Cordyceps, Pacillomyces sp. strain collected from Chilgab mountain area in Chungnam Province, Cordyceps pruinosa collected from Chiak mountain area in Gangwon Province and Pacillomyces japonica collected from dead silkworm larva at the rearing room in Sangju National University were used. Spores of cordyceps were propagated on sterile PDA (potato dextrose agar 39 g, water 1,000 mL) at 25℃ for 21 days. Spores of cordyceps isolated from media were inoculated on integuments of 3rd instar newly exuviated silkworm for pathogenicity on the silkworm larvae.
