沃尔巴克氏体是一种内共生细菌，通常感染节肢动物并引起宿主生殖障碍。在一些叶螨物种中，已经检测到沃尔巴克氏体，并显示其影响其繁殖。但对其在自然种群中的传播和分布模式了解甚少。本研究采用多位点序列分型方法对中国21个种群的5种叶螨（truncatchus、urticchus、pueraricchus、phaselus和kanzawai叶螨）进行了沃尔巴克氏体感染状态的鉴定，并分析了沃尔巴克氏体感染状态与宿主系统发育、线粒体多样性和地理范围的关系。沃尔巴克氏体在5种叶螨种群中的流行率为31.4% ~ 100%，菌株多样性显著。总之，这些观察结果表明沃尔巴克氏体是在多个不同的场合被引入这些种群的。和其他节肢动物一样，同样的叶螨物种可以适应非常不同的菌株，同样的沃尔巴克氏体偶尔会感染不同的物种。这些观察结果表明沃尔巴克氏体可以垂直和水平传播。水平传播可能由寄主植物介导。沃尔巴克氏体在同一种群间的分布格局存在较大差异，表明沃尔巴克氏体在自然界的动态可能受到生态等因素的影响。
Wolbachia are endosymbiotic bacteria that commonly infect arthropods and cause reproductive disorders in host. Within several Tetranychus species, Wolbachia have been detected and shown to affect their reproduction. However, little is known about their transmission and distribution patterns in natural populations of Tetranychus species. Here, we used multilocus sequence typing to confirm Wolbachia infection status and examined the relationship between Wolbachia infection status and host phylogeny, mitochondrial diversity, and geographical range in five Tetranychus species (Tetranychus truncatus, Tetranychus urticae, Tetranychus pueraricola, Tetranychus phaselus, and Tetranychus kanzawai) from 21 populations in China. The prevalence of Wolbachia within the five Tetranychus species ranged from 31.4 to 100 %, and the strains were remarkably diverse. Together, these observations indicate that Wolbachia was introduced to these populations on multiple separate occasions. As in other arthropods, the same Tetranychus species can accommodate very different strains, and identical Wolbachia occasionally infect different species. These observations suggest that Wolbachia are transmitted both vertically and horizontally. Horizontally, transmission is probably mediated by the host plants. The distribution patterns of Wolbachia were quite different among populations of the same species, suggesting that the dynamics of Wolbachia in nature may be affected by ecological and other factors.
