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 27° C and 80% relative humidity. Each bioassay had four treatments in concentrations of 10(5),10(6),10(7)e10(8) 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.
