| Summary: | Abstract Control potential of 10 Beauveria bassiana isolates, isolated from Hypera postica (Gyllenhal) (Coleoptera: Curculionidae) and Gonioctena fornicata (Brüggemann) (Coleoptera: Chrysomelidae), collected from alfalfa fields in Tokat province, Turkey, was evaluated against H. postica larvae under laboratory conditions. Concentration-response tests were carried out using the concentrations (1 × 103, 1 × 105, 1 × 107, and 1 × 109 conidia/ml) of isolates GN-23, GN-4, HP-30, and HP-6, which performed more than 95% efficacy in screening tests (1 × 107 conidia/ml) 5 days post treatments. LT50 and LT90 values at 1 × 109 conidia/ml were determined. According to the obtained results, H. postica larvae were susceptible to all the tested B. bassiana isolates. |
