[Variability in esterases of Metarhizium anisopliae]. / Variabilidad de las esterasas de Metarhizium anisopliae.

The variability in esterases of the entomogenous fungus Metarhizium anisopliae was determined electrophoretically on 8.5% polyacrylamide gel. Ten isolates from diverse taxonomic groups of insects were analyzed. The electrophoretic analysis showed differences and similarities between these isolates and it was possible to distinguish six different patterns. The results obtained show a great polymorphism for the esterase system of M. anisopliae.
