Mean mortality (%) ± standard error of Tenebrio molitor larvae 5 days after treatment, and Galleria mellonella 3 days after treatment.

Bioassays were performed 3 times (using two replicates for each isolate) under controlled conditions (27°C), using new batches of larvae and conidia in each bioassay. Controls were treated with Tween 80 (0.01%) solution. Means followed by the same letter in a column do not differ statistically (P ≥ 0.05) (Kruskal-Wallis test followed by Student-Newman-Keuls).
