我们解剖了遭受日本橡树枯萎病的锯齿栎树干，测量了豚草甲虫的甬道直径，并记录了豚草甲虫甬道中的相关昆虫区系。总共从 494 个画廊中捕获了 9 个物种的 545 只个体；这些属于九个物种[Cossoninaesp。 (Curculionidae)、Litargus japonicus Reitter (Mycetophagidae)、Platypus calamus Blandford (Platypodidae)、Platypus quercivorus(Murayama) (Platypodidae)、Ambrosiodmus lewisi(Blandford) (Scolytidae)、Ambrosiophilus atratusEichhoff （Scolytidae），Xyleborussp。 (Scolytidae)、Bitoma siccana Pascoe (Zopheridae) 和 Gempylodes Ornamentalis (Reitter) (Zopheridae)]。去皮原木表面上的廊道入口的直径可以作为估计本研究区域遭受日本橡树枯萎病的锯缘 Q.serrata 树中主要豚草甲虫的物种的线索。根据体宽与廊直径之间的关系、树内的分布模式以及分类学类比，推测一种蠕虫类 G.ornamentalis 可能是日本橡树枯萎病的致病因子 P.quercivorus 的捕食者和/或寄生虫。
We dissected the trunk of aQuercus serrataMurray tree that had suffered from Japanese oak wilt, measured the gallery diameters of ambrosia beetles, and recorded the related insect fauna in the galleries of ambrosia beetles. In total, 545 individuals of nine species were captured from 494 galleries; these belonged to nine species [Cossoninaesp. (Curculionidae),Litargus japonicusReitter (Mycetophagidae), Platypus calamusBlandford (Platypodidae),Platypus quercivorus(Murayama) (Platypodidae),Ambrosiodmus lewisi(Blandford) (Scolytidae),Ambrosiophilus atratusEichhoff (Scolytidae),Xyleborussp. (Scolytidae),Bitoma siccanaPascoe (Zopheridae), andGempylodes ornamentalis(Reitter) (Zopheridae)]. The diameter of the gallery entrance on the surface of a debarked log may serve as a cue for species estimation of major ambrosia beetles inQ.serratatrees suffering from Japanese oak wilt in this study area. From the relationships between the body width and the gallery diameter, the distribution pattern within the tree, and the taxonomical analogy, a zopherid species,G.ornamentalis, was inferred as a possible predator and/or parasitoid of a causal agent in Japanese oak wilt,P.quercivorus.
