The virulence of the tested strains was developed from environmental conditions. The strain V24 had a stable virulence at all temperature levels and achieved in relation to the other examined strains the highest mortality of infected insects. The other strains have shown different changes of effectiveness at the sub optimal conditions. Germination of blastospores was temperature depending and correlated in the mostly cases with the virulence.
测试菌株的毒力是由环境条件产生的。菌株V24在所有温度水平下都具有稳定的毒力，相对于其他被检测菌株，它使受感染昆虫的死亡率最高。其他菌株在次优条件下表现出不同的效力变化。芽生孢子的萌发取决于温度，并且在大多数情况下与毒力相关。
