RESULTS AND DISCUSSION
In the present study, several naturally available substrates of both solid and liquid media were tested for mass
multiplication of M. anisopliae. The success of microbial control of insect pests depends not only on the isolation,
characterization and pathogenicity, but also on the successful mass production of the microbial agents in the
laboratory. Large-scale availability of the pathogen is a primary requirement in the bio-control program. For a
successful integrated pest management program, the agents like the entomopathogenic fungi should be amenable
to easy and cheap mass multiplication.
The results (Table 1) showed that there were significant differences among the culture Medias tested, M.
anisopliae spore production on both media.
