摘　　要：对拟松材线虫发生区内46株萎蔫云南松上的主要蛀干害虫松墨天牛、纵坑切梢小蠹和马尾松角胫象甲进行采样、分离和镜检,结果表明:松墨天牛携带拟松材线虫,是拟松材线虫的主要媒介昆虫,纵坑切梢小蠹和马尾松角胫象甲未检出拟松材线虫.通过分析云南拟松材线虫的危害性提出防控对策.The major stem borers Monochamus alternatus, Tomicus piniperda and Shirahoshizo insidiosus were sampled from 46 stems of wilting Pinus yunnanensis in the occurrence area of Bursaphelenchus mucronatus, and the specimens were isolated and examined by microscope. It was showed by the results that Monochamus alternatus carried Bursaphelenchus mucronatus, which was assumed the main vector insect of B. mucronatus in Yunnan Province. There were no B. mucronatus found out from specimens of Tomicus piniperda and Shirahoshizo insidiosus. The control countermeasures were put forward based on analyzing the damage characteristics of B. mucronatus in Yunnan Province.
