Abstract
The studies of the Siberian isolates of Beauveria bassian а (Bals-Griv.) Vuill. fungus revealed that their viability and virulence were dependent on storage time at positive temperatures (8 °C or 18 °C ). It was proved that only at 8 °C the isolates kept their viability and virulence during 3 years. According to correlation anаlysis data, the virulence of the investigated fungus isolates at 18 °C depended mainly on storage time (57–72 %) and to a less degree on other uncontrolled factors (28–43 %).
