Molecular phylogenetic analyses show that Bursaphelenchus xylophilus evolved from B. xylophilus group nematodes that have a habitat preference for broad-leaved trees. This depends on cerambycid beetles (tribe Lamiini) that vector the nematodes from broad-leaved trees to conifers, namely, those that can use both broad-leaved trees and conifers as host trees. A field study showed that Acalolepta fraudatrix, which can use both broad-leaved trees and conifers, vectored Bursaphelenchus doui, a species in the B. xylophilus group. In addition, laboratory experiments indicated that B. doui could be vectored by both cerambycid beetles in broad-leaved trees and ones in conifers. Therefore, we suggest the possibility that B. doui was vectored from broad-leaved trees to conifers by A. fraudatrix, and then changed its vector from A. fraudatrix to Monochamus alternatus.

分子系统发育分析表明，松材线虫是由喜好阔叶树的松材线虫群进化而来的。这依赖于天牛(拉米尼部落)将线虫从阔叶树传播到针叶树，即那些既可以使用阔叶树又可以使用针叶树作为宿主树的线虫。一项田间研究表明，既可以利用阔叶树也可以利用针叶树的黄褐飞虱携带了松材线虫群中的一个物种--豆芽囊线虫。此外，实验室实验表明，杜氏杆菌可通过阔叶树上的天牛和针叶树上的天牛进行媒介传播。因此，我们认为豆芽孢杆菌可能是从阔叶树上传播到针叶树上，然后将其媒介从松墨天牛转变为松墨天牛。
