Aschersonia aleyrodis (Webber) one of the fungal entomopathogens utilized as a bio-control agent and was reported as the cause of epizootics amongst citrus black fly populations. The present study was aimed to find out cost effective suitable medium for mass multiplication of Aschersonia aleyrodis. Influence of synthetic, semi-synthetic culture media and food grains as solid substrate on growth and sporulation of A. aleyrodis was studied under laboratory condition. Amongst the different culture media tried, Potato dextrose agar and Asthana and Hawker’s media produced good growth (9.0 cm and 8.90 cm respectively) and abundant sporulation (2.31 x 106 and 2.12 x 106 spore/ml respectively) of A. aleyrodis within short span of time. Among the six food grains, sorghum as solid substrate resulted in highest spore (3.40 x 107 spore/ml) production and next best was maize (3.32 x107 spore/ml) proved to support the production of maximum spore load of tested fungus whereas rice and barley were least preferred substrate in producing the spores (1.44 x 107 spore/ml and 1.13 x 107 spore/ml respectively.
