Xylosandrus compactus associated fungi

Ambrosia beetles such as Xylosandrus spp. establish a symbiosis with microfungi. Some fungal taxa such as Ambrosiella xylebori are providing the diet for the larvae of the insects in the galleries where they find an optimal environment for their growth. Others, such as Fusarium spp. or Raffaelea spp. , are pathogenic to host plants causing different level of damages including shoot wilt, necrosis and stem cankers. Symbiotic fungi are associated to a specific structure of the insect, the mycangium, but are also present on other parts of the insect body.

食菌小蠹（Ambrosia beetles）如截尾材小蠹属（Xylosandrus spp.）物种，可与微型真菌建立共生关系。部分真菌类群，如食菌长喙霉（Ambrosiella xylebori），会在蛀食形成的虫道中为昆虫幼虫提供食物来源，而该虫道恰好为真菌的生长提供了最优环境。另有部分真菌类群，如镰孢霉属（Fusarium spp.）、莱菲霉属（Raffaelea spp.），则对寄主植物具有致病性，可引发不同程度的危害，包括梢枯、组织坏死以及茎溃疡。共生真菌通常与昆虫的特定结构——贮菌器（mycangium）相关联，同时也可在昆虫身体的其他部位被检测到。
