Trends of conidial survival indices (Is) of four B. bassiana strains over the intensities of wet-heat stress at 45°C (A) and UV-B irradiation (B). rHV8 and rWT were recovered from the HV8 and WT treatment plots 90 days after the last spray of trial 1. The inset bar charts illustrate their LT50s (min) and LD50s (J/cm2) under the heat and UV-B stresses. Different lowercase letters on the bars denote significant differences (Tukey's HSD, P < 0.05). Error bars indicate SEMs from four repeated assays.
