ABSTRACT
This study was aimed at developing a physical extraction method of M. ansiopliae and B. bassiana conidia from precooked rice culture media by agitation with inerts. Evaluation was made of the abrasive effect of the following inerts: Caulin SAZ, Caulin ML, Filito Cremogeo, Argila Lopes, Diatomita and Leucita Calcinada, at different times of the agitation. It was verified that Diatomita was the most efficient for M. anisopliae conidia extraction and the sieve for B. bassiana.
