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