微生物为食草性寄主提供多种生理功能。叶螨(Tetranychus)是世界范围内重要的农业害虫，但其微生物群落的组成，尤其是肠道微生物群落的组成尚不清楚。在这里，我们通过对16S rRNA基因的深度测序，调查了五种蜘蛛螨类及其相关粪便中的细菌群落。5种流行蜘蛛的细菌群落组成存在明显差异，部分细菌共生体表现出种间特异性。此外，蜘蛛粪便中细菌群落的丰度显著高于相应的蜘蛛粪样。然而，在所有样品中都检测到了黄杆菌，并代表了一个“核心微生物群”。值得注意的是，在蜘蛛和粪便中都检测到了母系遗传的内共生沃尔巴克氏菌。总体而言，这些结果为了解蜘蛛体内复杂的共生体群落提供了洞察，并为未来的研究提供了新的方向。
Microorganisms provide many physiological functions to herbivorous hosts. Spider mites (genus Tetranychus) are important agricultural pests throughout the world; however, the composition of the spider mite microbial community, especially gut microbiome, remains unclear. Here, we investigated the bacterial community in five spider mite species and their associated feces by deep sequencing of the 16S rRNA gene. The composition of the bacterial community was significantly different among the five prevalent spider mite species, and some bacterial symbionts showed host‐species specificity. Moreover, the abundance of the bacterial community in spider mite feces was significantly higher than that in the corresponding spider mite samples. However, Flavobacterium was detected in all samples, and represent a “core microbiome”. Remarkably, the maternally inherited endosymbiont Wolbachia was detected in both spider mite and feces. Overall, these results offer insight into the complex community of symbionts in spider mites, and give a new direction for future studies.
