摘　　要：调查了云南暖热性针叶林区思茅松重要蛀干害虫种类、蛀干特点和蛀害次序,并检测了蛀干害虫的线虫携带情况。共记录思茅松主要鞘翅目蛀干害虫7种:小蠹科3种,象甲科2种,天牛科1种,叩甲科1种。各蛀干害虫均为次期性,能够加速但不直接导致寄主树死亡。松墨天牛Monocha-mus alternatus携带松材线虫Bursaphelenchus xylophilus和拟松材线虫B.mucronatus;思茅四眼小蠹Polygraphus szemaoensis、云南四眼小蠹P.junnanicus和额毛小蠹Dryocoetes luteus携带拟松材线虫,未发现携带松材线虫;马尾松角胫象Shirahoshizo patruelis、松瘤象Hyposipalus gigas和豹纹斑叩甲Cryptalaus sordidus未发现携带上述两种线虫。The species, damage characteristics, occurring sequence and nematode carrying status or me important stem borers in Pinus kesiya var. langbianensis stands of warm-hot coniferous forests in Yunnan Province were investigated. Seven species were recorded including three species of Scolyidae, two species of Curculionidae, one species of Cerambycidae and one species of Elateridae. All of them caused secondary damage that fastened but didn＇ t directly cause the death of the hosts. Monochamus alternatus carried both Bursaphelenchus xylophilus and B. mucrotatus. Polygraphus junnanicus, P. szernaoensis and Dryocoetes luteus carried B. mucronatus only. Shirahoshizo patruelis,Hyposipalus gigas and Cryptalaus sordidus carried neither of the nematodes.
