| Abstract | Beauveria bassiana s.l. is a cosmopolitan fungus used in the control
of different species of arthropods. The current study explored the
virulence for ticks, proteolytic and lipolytic activities of 10 Brazilian
B. bassiana s.l. isolates. For this purpose, Rhipicephalus microplus
biological parameters was evaluated after immersion of the
engorged females in fungal suspension (108 conidia mL−1) and
the enzymatic activities were performed posteriorly the fungal
growth in minimal medium. After the biological assays, five
isolates changed all parameters analysed with highest efficacy of
approximately 61% (CG 206) and 66% (CG 481). However, we
observed that the most virulent isolates did not show the highest
enzymatic activities. Interestingly, CG 500, considered an isolate of
intermediate efficacy, demonstrated higher enzymatic activities
than the other isolates in four of five analyses (total protease, Pr1,
Pr2 and lipase; p < .05). Based on these data, it seems reasonable
to suggest that these enzymatic activities should not be used as
markers of virulence for these fungal isolates. It is noteworthy that
complementary studies regarding chitinase analyses, gene
expression, production of toxins and hydrophobicity of conidia
can be used in the selection of pathogenic isolates. | pt_BR |
