A number of media for culturing and mass propagation of the enthomopathogenic fungus, Bueaveria bassiana strain NBCRSO1 were screened under laboratory condition. At 25-30 deg C the artificial media, Sabouraud Dextrose Agar (SDA) and Malt Extract Agar(MEA) were the most suitable ones.They promoted highest mycelium growth rate and sporulation averaging 0.33 +- 1.24 cm per day and 7.28 +- 1.07 x10sup8 spores per ml respectively.Likewise steamed sorghum seed was the most suitable medium for its mass propagation. It could promote within a 14 day period averaging 100%, 99.33 +- 1.54% and 1.2 +- 1.1 x 10sup10 spores/ml respectively for hyphal colonization, proportion of sporulation area on the media, and spore concentration.The results from this preliminary study could be further applied for the utilization of B. bassiana as a microbial control of several insect pest species adopting this simple method for mass propagation by the small farmers.
