The aim of the study was to select native strains of Beauveria bassiana with toxic activity against Aedes aegypti (L.). For the bioassays, third-instar larvae of the mosquito were put into 200-ml plastic containers inoculated at an initial concentration of 1 × 106 conidia/ml of 17 strains of B. bassiana. The most-pathogenic strains were selected, and HIB-10 and HIB-4 at different concentrations (1.30 × 104, 1.30 × 105, 1.30 × 106, and 1.30 × 107 conidia/ml) were used to determine LC50 and LT50. For HIB-10, HIB-4, and GHA strains, the LC50 was 1.37 × 106, 5.87 × 105, and 4.90 × 105 conidia/ml, while LT50 was 7.2, 8.3, and 8.5 days, respectively.
