Ficus carica plantations in Japan were first reported to be infested by an ambrosia beetle species, identified as Euwallacea interjectus, in 1996. The purpose of this study was to determine the symbiotic fungi of female adults of E. interjectus emerging from F. carica trees infected with fig wilt disease (FWD). Dispersal adults (51 females) of E. interjectus, which were collected from logs of an infested fig tree in Hiroshima Prefecture, Western Japan, were separated into three respective body parts (head, thorax, and abdomen) and used for fungal isolation. Isolated fungi were identified based on the morphological characteristics and DNA sequence data. Over 13 species of associated fungi were detected, of which a specific fungus, Fusarium kuroshium, was dominant in female head (including oral mycangia). The plant-pathogenic fungus of FWD, Ceratocystis ficicola, was not observed within any body parts of E. interjectus. We further discussed the relationship among E. interjectus and its associated fungi in fig tree.

榕树 据报道，日本的人工林被一种豚草甲虫侵染，确定为 桉树, 在 1996 年。这项研究的目的是确定雌性成虫的共生真菌 E. interjectus 来自 F. carica感染无花果枯萎病 (FWD) 的树木。散播成虫（51 名女性）E. interjectus，从日本西部广岛县一棵受感染的无花果树的原木中收集，被分成三个各自的身体部位（头部、胸部和腹部）并用于真菌分离。基于形态特征和DNA序列数据鉴定分离的真菌。检测到超过 13 种伴生真菌，其中一种特定真菌、黑镰刀菌, 以女性头部为主（包括口腔肌瘤）。FWD的植物病原真菌，角囊藻, 在任何身体部位均未观察到 E. interjectus. 我们进一步讨论了两者之间的关系E. interjectus 及其在无花果树中的相关真菌。
