摘　　要：通过对松材线虫病疫区黑松、马尾松松材线虫病死木的树干解剖发现,90 %的黑松和83.3 %的马尾松 病死木有松褐天牛产卵痕、幼虫蛀入孔和成虫羽化孔,但也有部分是松褐天牛补充营养时带入线虫而致病的。松褐天牛活动区域主要集中在树干的中部或中下部,但随树高的增加而拉伸;黑松、马尾松上松褐天牛幼虫蛀入孔总数比产卵痕总数分别下降了41.88 %和37.45 %;成虫羽化孔总数比幼虫蛀入孔总数分别下降了19.17 % 和28.26 %;离地50 cm内树干基部及直径3 cm以上的梢头也有松褐天牛幼虫蛀入和成虫逸出,在生产中应引起注意。Anatomy of dead Pinus thunbergii and P. massoniana caused by Bursaphelenchus xylophilus demonstrated that 90% P. thunbergii and 83.3% of P. massoniana had egg laying, bore and emergence hole of Monochamus alter-natus which was the major infection cause. The result also showed that bore hole in P. thunbergii and P. massonianadecreased 41.88% and 37.45% than egg laying hole, emergence hole decreased 19.17% and 28.26% than bore hole.
