Conteúdo: | Nine pathotypes of Beauveria bassiana (Bals.) Vuill and one pathotype of B. brongniartii (Sacc.0 Petch were characterized according to extracellular enzyme production, growth rate on different culture media, conidial dimensions, conidiogenesis in vitro, esoenzyme variation, and virulence toweard Diatraea saccharalis. Biological differences were found among isolates only one isolate showed lipolytic activity. Two isolates had limited growth at three levels of temperature LT50 value ranged from 5,9 days (virulent) to more than 8 days (non virulent). Electrophoretic analysis from alfa and beta - esterases were performed to differentiale isolates. Pairwise coefficients of similarity calculated from these parameters were used to construct phenograms in order to est imate the phenetic distance among the various fungal pathotypes. Isolates from the same regions had high coefficients of similarity, suggesting commonality within geographic populations.
