Growth of Metarrhizium flavoviride var. minus and Hirsut lle strigosa showed good yield in the carbon source media adding dextrose, starch and saccharose, but Hirsutella sp. from korea greq well in the other media except in the dextrose media. Yeast extract was necessary for the mecelial growth of the fungi, but the fungi tested in this experiment showed a difference in the amount of required yeast extract. Growth of Nomurea rileyi was fastidious in the carbon and nitrorgen sourced media and the optimum pH of the media for growth was at 6.7. Sporulation of M. Flavoviride var. minus was high on media, containing 1%~2% of yeast extract as nitrogen and carbon source media, but N. rileyi sporulated abundantly on the media with nitrogen and dextrose.
