Wolbachia are maternally inherited endosymbiotic alpha-proteobacteria found in terrestrial arthropods and filarial nematodes. They are transmitted vertically through host cytoplasm and alter host biology by inducing various reproductive alterations, like feminization, parthenogenesis, male killing (MK) and cytoplasmic incompatibility. In butterflies, some effects especially MK and sperm-egg incompatibility are well established. All these effects skew the sex ratio towards female and subsequently favor the vertical transmission of Wolbachia. Some of the insects are also infected with multiple Wolbachia strains which may results in some complex phenomenon. In the present review the potential of Wolbachia for promoting evolutionary changes in its hosts with emphasis on recent advances in interactions of butterfly-Wolbachia is discussed. In addition to this, strain diversity of Wolbachia and its effects on various butterfly hosts are also highlighted.
沃尔巴克氏体是一种共生的α-变形菌，通过母系遗传方式在陆地节肢动物和丝虫中传播。它们通过诱导各种生殖改变，如雌性化、孤雌生殖、雄性致死（MK）和细胞质不亲和性，垂直地在宿主细胞质中传播，并改变宿主生物学。在蝴蝶中，一些效应，特别是 MK 和精子-卵子不亲和性已经得到很好的证实。所有这些效应都使性别比例偏向雌性，从而有利于沃尔巴克氏体的垂直传播。一些昆虫也被多种沃尔巴克氏体菌株感染，这可能导致一些复杂的现象。在本综述中，讨论了沃尔巴克氏体促进宿主进化变化的潜力，重点是最近在蝴蝶-沃尔巴克氏体相互作用方面的进展。除此之外，还强调了沃尔巴克氏体菌株的多样性及其对各种蝴蝶宿主的影响。
