RESUMO
The in vitro susceptibility of Amblyomma cajennense engorged females to some isolated of the fungus Beauveria bassiana and Metarhizium anisopliae was verified and lethal concentrations (LC 50 and LC 90) were calculated. The females were dived in conidia suspensions for five minutes, and kept in climatically controlled chambers BOD under 27º C and 80 por cento relative humidity. Each bioassay had four treatments in concentrations of 105,106,107 e 108 conidia/ml. A control group was also used. The following characteristics were evaluated weight and period of oviposition, indexes of reproductive and nutritional efficiency and percentage of microbiological control. A dose dependent negative effect was observed in ticks treated with the suspension. All isolates tested cause a negative effect on in vitro tests of engorged females of A. cajennense, suggesting its potential for microbiological control of tick's species.
