The virulence of the MaSom1-overexpression strains was increased. (A). The locust survival rates after topical inoculation of paraffin oil conidial suspension for WT, OE-4, OE-34, OE-55 and VT strains, respectively. (B). The LT50s of WT, OE-4, OE-34, OE-55 and VT strains. (C). The DNA concentrations of the WT, MaSom1-overexpression and VT strains in locust hemolymph in vivo after topical inoculation for 3 and 5 days. (D). The microscopic observation of the hyphal bodies of fungal strains in locust hemolymph in vivo. Bar =10.0 µm. Different lowercase letters on bars denote significant differences between samples for p < 0.05.
