塔达米氏Bursaphelenchus tadamiensis最初是从日本东北部福岛栎树液流中采集的一种雄甲虫Dorcus striatipennis中分离出来的，从栎树液流中重新分离了三次。在日本西部。重新分离的种群在形态上大多与型种群一致，但雄性法氏囊瓣在新采集的种群中表现出较大的变异。从分子结构上看，新居群与旧居群在核糖体DNA内部转录间隔区和线粒体细胞色素氧化酶亚基I基因上存在差异，表明该物种在遗传上被划分为几个局部居群。b的隔离模式。tadamiensis,即。该物种最初是从液流相关的甲虫中分离出来的，随后又从液流中分离出来，这表明该物种更喜欢并适应液流环境作为其栖息地。
Bursaphelenchus tadamiensis, which was initially isolated from a stag beetle,Dorcus striatipennis, collected from sap flow ofQuercus crispulain Fukushima, north-eastern Japan, was re-isolated three times from sap flow ofQuercusspp. in western Japan. The re-isolated populations were mostly morphologically consistent with the type population, but the male bursal flap showed high variations in the newly collected populations. Molecularly, the type and new populations showed differences in the internal transcribed spacer region of ribosomal DNA and mitochondrial cytochrome oxidase subunit I gene, suggesting that the species is genetically divided into several local populations. The isolation pattern ofB. tadamiensis,i.e., the species was initially isolated from sap flow-associated beetles and subsequently isolated from sap flow, suggests that the species prefers and is adapted to the sap flow environment as its habitat.
