| 摘 要： | 纵坑切梢小蠹（ＴｏｍｉｃｕｓｐｉｎｉｐｅｒｄａＬ．）是松科（Ｐｉｎａｃｅａｅ）树木的主要蛀食性害虫，分布遍及国内各省、自治区［１，２］，在云南该虫主要危害云南松（ＰｉｎｕｓｙｕｎｎａｎｅｎｓｉｓＬ．）。近１０多年来，云南松蠹害林已达数十万公顷，给当地林业生产和生态环境造成了严重破坏［３～５］。国外对小蠹虫侵害机理及暴发成因的深入研究，揭示了小蠹虫携带的病原性伴生真菌在蠹害过程中发挥重要作用。如：伴生真菌是云杉八齿小蠹（ＩｐｓｔｙｐｏｇｒａｐｈｕｓＬｉｎｎａｅｕｓ）成功定殖的先决条件［６］；对于栎…

| Abstract: | Egg galleries of Tomicus piniperda attacking Pinus yunnanensis were investigated during different period of trunk attack in mid Yunnan Province. 30 Genus of fungi,which belong to 12 families,were isolated. Among them,12 are saprophytes,10 facultative fungi and 8 parasites. Moreover,there is no obvious differentiation in the dominant populations including Debaryomyces,Penicillium and Paecilomyces with the damage level of localities and there exists no close interior relation between bark beetle attacks and dominant populations. Besides these,blue stain fungi which identified as Leptographium spp.were isolated from Tomicus piniperda and trunk tunnels. |
