在胚胎发生过程中杀死雄性宿主的遗传细菌感染了多种昆虫物种。为了确定宿主感染是否存在模式，即特定的雄性杀伤细菌专门针对特定的分类群，我们研究了蝴蝶 Hypolimnas bolina 的雄性杀伤特征。 20 世纪 20 年代首次报道了该物种的全雌性幼崽。对斐济群岛这一系统的调查表明，H. bolina 性别比例扭曲的致病因素是一种雄性杀灭沃尔巴克氏体细菌。这种细菌的 wsp 和 ftsZ 序列与坦桑尼亚 Acraea encedon 蝴蝶中的雄性杀手相同，表明它已在宿主物种之间移动，但保留了其表型。对斐济三个不同岛屿群的沃尔巴克氏体患病率进行了计算，发现全国各地的沃尔巴克氏体患病率存在显着差异。抗生素未能治愈雄性杀伤性状或沃尔巴克氏体感染。讨论了这些结果的含义。
Inherited bacteria that kill male hosts during embryogenesis infect a wide range of insect species. In order to ascertain if there are patterns to host infection, with particular male killing bacteria specialising on particular taxa, we investigated the male killing trait in the butterfly Hypolimnas bolina. All-female broods were first reported in this species in the 1920s. Investigation of this system in the Fiji Islands revealed the causal agent of sex ratio distortion in H. bolina to be a male killing Wolbachia bacterium. This bacterium is identical in wsp and ftsZ sequence to a male killer in the butterfly Acraea encedon in Tanzania, suggesting it has moved between host species, yet retained its phenotype. The prevalence of the Wolbachia was calculated for three different island groups of Fiji, and found to vary significantly across the country. Antibiotics failed to cure either the male killing trait or the Wolbachia Infection. The implications of these results are discussed.
