Metarhizium anisopliae var. anisopliae and Metarhizium flavoviride var. flavoviride are entomopathogenic fungi with proved action against several species of insects. In this work, the behavior and cytology of the M. anisopliae var. anisopliae (PL43) and M. flavoviride var. flavoviride (CG291) were evaluated after the passage in eggs, larvae and adults Chrysomya albiceps, an important causer of secondary myiais. The experiment was carried out under an acclimatized environment's humidity and temperature of 60 ± 10% and 28 ± 1oC. The most expressive results of the biological parameters studied (percentage of germination, quantity of conidia, quantity and diameter of colonies) were reached from re-isolated fungi of larvae. No significant differences were observed in the cytological aspects of the life cycle of the fungi post-passage in eggs, larvae and adults. These results suggest the possibility of the use of the fungi in the control of C. albiceps fly.
