沃尔巴克氏体是一组母系遗传的细菌，感染广泛的节肢动物。已知沃尔巴克氏体感染会导致各种异常生殖表型的表达，最著名的是细胞质不相容性。首次对日本42种叶螨进行的系统调查显示，有7种（16.7%）被Wolbachia感染。通过wsp基因的系统发育分析，将叶螨体内的沃尔巴克氏体分为超群B的三个亚群。大多数红蜘蛛没有表现出细胞质不相容性时，感染的男性与未感染的女性。然而，所有的感染群体的桑全爪螨和小爪螨gotohi（5个和4个人口，分别）具有沃尔巴克氏体的修饰阳性菌株，和细胞质的不亲和性降低卵孵化率和雌性比例的叶螨。因此，一些沃尔巴克氏体菌株在其宿主中引起性别比例扭曲。
Wolbachia are a group of maternally inherited bacteria that infect a wide range of arthropods. Wolbachia infections are known to result in the expression of various abnormal reproductive phenotypes, the best known being cytoplasmic incompatibility. The first systematic survey of 42 spider mite species in Japan revealed that seven species (16.7%) were infected with Wolbachia. Wolbachia in the spider mites were grouped into three subgroups in supergroup B by phylogenetic analyses of the wsp gene. Most spider mites did not show cytoplasmic incompatibility when infected males were crossed with uninfected females. However, all infected populations of Panonychus mori and Oligonychus gotohi ( five and four populations, respectively) possessed modification-positive strains of Wolbachia, and the cytoplasmic incompatibility decreased egg hatchability and female ratio of the spider mites. Thus, some Wolbachia strains cause sex ratio distortion in their hosts.
