Two blue-stain fungi associated with Ips typographus were tested and the results show that to two strains of blue -stain fungi, the optimum temperature were all 25℃, and their adaptability to pH were strong .They could grow under pH3.5~9.0, and they grew better in acidic environment .Optimum growth carbon source was glucose and fructopyranose .Optimum growth nitrogen sources were glycine .In addition, Ophiostoma penicillatum 1 could make good use of yeast extract .Mildothane and Iprodione were the most effective fungicides , Chlorothalonil and Zhongshengmycin only has significant inhibitory effect to Ophiostoma penicillatum 2 .%通过对2个云杉八齿小蠹伴生蓝变真菌的试验研究，结果表明：2个蓝变菌菌株适宜生长温度均为25℃；对酸碱度的适应能力强，在pH4．0～9．0范围内均能生长，在酸性环境下发育较好；以葡萄糖和果糖为最佳碳源，最佳氮源为甘氨酸，此外菌株Ophiostoma penicillatum 1也可很好利用酵母粉．甲基托布津、扑海因对2个试验菌株的生长有极强的抑制效果，百菌清和中生菌素仅对Ophiostoma penicillatum 2有很强的抑制效果，可杀得和硫酸链霉素对所有菌株的抑制作用均不明显．
