摘　　要：研究了江苏南京和浙江舟山地区松材线虫病木标本,并进行分离培养,得到10多种真菌,其中Ophiostoma ips,Ophiostoma lignicola,Sphaeropsis salicicola,Dothiorella gregaria和Haplosporella minor出现的最多;在Ophiostomaspp.和Cephalosporium zonatum的培养皿中出现大量的线虫。在天牛的蛹室和虫道中有大量的长喙壳真菌存在,并与线虫的关系密切。实验证明Sphaeropsis salicicola,Dothiorella gre-garia、Haplosporella minor能引起严重的松木变色。9 genera fungi and bacteria were isolated from diseased pine wood attacked by Bur saphelenchus xylophilus （Steiner ＆ Bubrer） Nickle in Nanjing area of Jiangsu province and Zbousban area of Zbejiang province of China. Identified as Ophiostoma ips ,Ophiostoma lignicola, Sphaeropsis salicicola, Dothiorella gregaria , Haplosporella minor, Trichoderma koningii , Penicillium verruculosum. , Cephalosporium zonatum , Chaetomium globosum and Aspergillus sp.. There are many peritbecia of Ophiostoma spp. in longhorn tunnel and pupa cell, and close relationship between Ophiostoma spp. and B. xylophilus. A very serious pine wood stain was caused by Sphaeropsis salicicola, Dothiorella gregaria and Haplospo rella minor.
