Cordyceps militaris is a entomopathogenic ascomycetous fungus and cultivated as a medicinal mushroom having many valuable biological and pharmaceutical activities. It was cultivated on five different grain media which were compared with silkworm pupa medium for the artificial fruiting body production. C/N ratio of pupa and bean media was low at 5.9 and 5.8 respectively, which was attribute to low nitrogen contents compared to others. The various media had a significant effect on mycelial growth, cordycepin contents, fruiting body production. The mycelial growth were greatest at barley and wheat media but least at pupa medium. The cordycepin contents were highest at bean and pupa media with 2.9 and 2.6 mg/g, respectively. This was followed by wheat, corn, barley and brown rice media. The yield of fruiting body was greatest at barley and wheat media but the yield and days to harvest were least at silkworm pupa medium.
