松材线虫（Bursaphelenchus xylophilus）是引起黄松（pinus thunbergiiandP.）萎蔫病的病原体。densiflorain日本。该线虫是由天牛属的天牛甲虫传播的。据推测，它是在20世纪初从北美引进的，然后分布在中国、韩国和台湾。对松材枯萎病系统的深入和/或长期研究已经阐明了线虫在松林内的传播模式和机制、病媒甲虫的扩散以及松材枯萎病在地区内的传播模式。线虫在松林中的传播模型，包括甲虫在松林内的繁殖，一直在发展中，并应阐明影响线虫范围扩张速度的因素。在这篇综述中，我们总结了线虫、甲虫和树的生物学特征，然后描述了线虫在松林内、在松林内和在单位行政区域内的传播特征。线虫的局部传播和区域传播主要与昆虫媒介的远距离传播和人工运输侵染了线虫及其媒介的松材有关。
The pinewood nematode,Bursaphelenchus xylophilus, is the causative agent of pine wilt ofPinus thunbergiiandP. densiflorain Japan. The nematode is vectored by cerambycid beetles of the genusMonochamus. It is inferred to have been introduced from North America early in the 1900s and then to have distributed in China, Korea, and Taiwan. Intensive and/or long-term studies of pine wilt systems have elucidated the pattern and mechanism of the nematode’s spread within a pine stand, dispersal of vector beetles, and spread pattern of pine wilt within a prefecture. The modeling of nematode spread over pine stands, which involves beetle reproduction within a pine stand, has been developing and should elucidate the factors influencing the rate at which the nematode range expands. In this review, we summarize the biologies of the nematode, beetle, and tree, and then characterize the spread of the nematode within a pine stand, locally over pine stands, and regionally over unit administrative districts. Local and regional spreading of the nematode is related primarily to long-distance dispersal by insect vectors and to the artificial transportation of pine logs infested with the nematode and its vector, respectively.
