摘要
Abstract
In this experiment,the mycelium of Beauveria bassiana was separated from infected hyphantria cunea pupae before it was purified.The effect of humidity and ultraviolet radiation on the mycelium growth,spores germ ination and the pathogenicity against hyphantria cunea larvae of a Beauveria bassiana strain were tested.The results showed that the optmium relative humidity for mycelium growth and spores germ ination was RH 90%,and at RH 90% hyphantria cunea larvae had highest motality.The germ ination speed and rates of spores increased as the RH increasing,and the 3rd larvae died more quickly than the 6th under 90% RH.The rates of spores decreased for irradiated by ultraviolet radiation.关键词
