云杉八齿小蠹（Ips typographus）分布范围广，可危害多种健康和衰弱的云杉（Picea asperata）和松属树种。幼虫危害初期在树干坑道内取食，植株生长正常；危害中期被害树干上可见小蠹羽化孔，树皮较易剥离，针叶变色；严重危害时树皮极易剥落。由于其适应性强，危害存在隐蔽性，该虫对我国北方针叶林造成重大经济危害。通过对云杉八齿小蠹的风险分析，其风险评估值R=1.85，在我国属中度危险的林业有害生物。

Ips typographus is widely distributed and can damage many kinds of picea asperata and pinus species. The lavra will take the food from inside of the trunk tunnel during the early damage stage, and the growth of plantlet is normal. There are many emergence ho les on the trunk during the harm of interim, with the bark falling and the color of needle changing. Serious damage will cause great economic loss to the spruce and timber product. According to the risk analysis ofIps typographus, the value of risk evaluation forR was 1.85, and belonging to the moderate dangerous forest pest in China.
