摘　　要：松树材小蠹Xyleborus festivus Eichhoff是东南亚地区为害松属植物的重要害虫,为掌握该虫在中国南方的发生情况及其共生真菌种类,本文通过检视标本馆标本和野外调查,并对采集的标本携带的真菌进行分类培养,利用分子生物学的方法对获得的真菌种类进行鉴定。本文提供了松树材小蠹的鉴别特征,记录了其在中国南方的发生情况、地理分布、寄主等,同时分离出共生真菌7种,并确定其储菌囊中的优势真菌--Raffaelea cf.arxii。松树材小蠹对寄主植物的危害极有可能引起或加速其他病害发生,应引起相关部门的重视。The ambrosia beetle, Xyleborus festivus Eichhoff, is a widespread and dominant ambrosia beetle on pines in Southeast Asia, but it has not yet been reported from China. Here we reported the distribution, host range, and symbiotic fungi of X.festivus in China by using newly collected data and information from the National Zoological Museum of China(NZMC), Chinese Academy of Science(IZCAS) and the University of Florida. X.festivus infested Pinus kesiya, P.massoniana, P.yunnanensis, and P.taiwanensis. It occurred in south China including Yunnan, Guizhou, Guangxi, Guangdong, Fujian and Taiwan. A redescription, illustration, and identification of similar species were included. The symbiotic fungi of X.festivus were isolated from their mycangia. Seven fungi were obtained, of which Raffaelea cf. arxii dominated in the mycangia of beetle from various locations.
