Entomopathogenic fungi have been known as promising candidates in biological control. However, a large number of conidia with higher stability should be produced for industrialization. In this work investigated the possibility of several grains for the production of thermotolerant Isaria javanica and I. fumosoroseus conidia. The fungal conidia were produced on ten grains for 14 days in Petri dish conditions. Of the ten granular substrates, millet, perilla seed and barley showed the high conidial production, 15.7 ± 8.4, 17.3 ± 5.2 and 13.5 ± 1.9 × 109 conida/g in I. javanica and 15.9 ± 0.6, 15.0 ± 0.5 and 15.0 ± 0.7 ×109 conida/g in I. fumosoroseus, respectively. However, the two strains showed relatively low thermal stability regardless of substrates, when exposed to 45℃ for 1, 2 and 3 hours. This work suggests a possible substrate for conidial production of entomopathogenic fungi with low cost.
