Germination (percent) of spores of Beauveria bassiana after long term storage under varying conditions. A) Germination of spores removed from 7°C after 580 days and subsequently maintained at 22°C, 26°C or 32°C. B) As for A) but spores were taken from the refrigeration conditions after 580 days and subsequently maintained in open glass beakers placed in incubators with relative humidity at 80% and temperatures of 22°C, 26°C and 32°C. Blue line is for germination of spores at 7°C across the monitoring period (same for both graphs as a reference), orange points spores kept at 22°C, green points spores kept at 26°C and purple points spores kept at 32°C. Curves are Weibull survival functions fitted through the germination data at each temperature. R² and parameter values can be found in Table1.
