It has recently become a serious problem in Antalya (southwestern Turkey) due to its high resistance to insecticides used. To address this problem, the present study aimed to evaluate the pathogenicity of five indigenous <i>Beuveria bassiana</i> (Balsamo) Vuillemin (Deuteromycotina: <i>Hyphomycetes</i>) isolates (BbFn-2, BbKm-2, BbSr-2, BbDs-4, and BbDm-2) with high virulence in previous studies against the pest. All the isolates were tested at five different conidial concentrations (1 × 10⁵, 1 × 10⁶, 1 × 10⁷, 1 × 10⁸ and 1 × 10⁹ conidia mL⁻¹) against the nymphs and adults of <i>A. gossypii</i> using Petri dish and pot trials in the laboratory. The results from the bioassays showed that virulence of the isolates increased significantly with elapsed time up to 10 days after inoculation. All five <i>B. bassiana</i> isolates at the highest concentration (1 × 10⁹ conidia mL⁻¹) caused mortalities ranged from 83.3% to 100% in both nymphs and adults 10 days post-treatment. While the LT₅₀ and LT₉₅ values of the isolates were 1.72–2.12 days and 4.81–8.49 days, respectively, for the nymphs, they were calculated for the adults as 1.65–2.54 days and 4.66–12.93 days, respectively. Results of the phylogenetic analysis showed that these five <i>B. bassiana</i> isolates had high similarities (ranging from 99 to 100%) with the other <i>B. bassiana</i> isolates in GenBank.
