Four native isolates of Beauveria bassiana were evaluated for food consumption and mortality over time against adults of Asynonychus cervinus (Boh.) through inoculation at different concentrations (0-10⁸ conidia mL^-1). The results indicated that food intake of insects treated with B. bassiana decreased linearly, reducing 70% consumption after 35 days. As to mortality, no differences were observed among the four isolates, all were lethal for A. cervinus and the deadliness increased with the concentrations of the isolate. From the mortality curves, the lethal concentrations LC₅₀ and LC₉₀ were calculated, and the best isolate (Qu-B299) had values of 1x10^4.7 and 1x10^8.3 conidia mL^-1, respectively.
