Impacts of each pr1 deletion on the virulence of B. bassiana. (a, b) Survival trends of G. mellonella larvae after topical application (immersion) of a 107 conidia/ml suspension for normal cuticle infection and LT50 estimates as virulence indices of all tested strains estimated from time-morality trends. The asterisked Δpr1 LT50 s differ significantly from those of the corresponding control strains unmarked (Tukey’s HSD, P < 0.05). (c) LT50 estimates of all tested strains against G. mellonella larvae inoculated by intrahaemocoel injection of ~500 conidia per larva for cuticle¯bypassing infection (see Figure S4 for survival trends of injected larvae). Note no significant variability among the LT50 s of all tested strains. Error bars: SD from three replicates.
