The result showed that the optimum culture medium was PPDA,the optimum temperature for the mycelium growth and spore germination was 26 ℃,and A. glabripennis larvae had the highest mortality from the fungus at this temperature. The optimum RH for the mycelium growth ranged from 95%to 100%. The speed and rate of spore germination increased with increasing of RH. The larvae died from the fugus most quickly and the mortality reached the highest under 100% RH.展开更多
