Evaluation of mortality, color change, and developmental stage of G. mellonella larvae in the treatments inoculated with different doses of the metabolite extract. (a) Mortality. (b) Color change. (c) Effect of the metabolite extract from the supernatant of the B. pseudobassiana RGM 2184 cell culture on G. mellonella larvae after 21 days post-injection. (d) Percentage of different developmental stages of individuals in the treatments (moth, pupa, and larva). Ten fifth instar larvae of G. mellonella were injected with different doses of the secondary metabolite extract. The control treatment (0 μg/larva). The averages of the values ± SD of the treatments performed in triplicates are expressed. Different letters indicate significant differences (p < 0.05, ANOVA, LSD).
