杀雄细菌广泛存在于节肢动物中，可以深刻地改变其宿主物种的生殖生物学。在这里，我们详细介绍了第一个完全压制男性杀手的案例。蝴蝶Hypolimnas bolina感染了一种Wolbachia细菌wBol 1，它会杀死波利尼西亚种群中的雄性宿主胚胎，但在东南亚的许多地区不会这样做，那里的雄性和雌性成年人都自然感染，感染wBol 1的雌性产生1：1的性别比例。我们证明，wBol 1的男性杀戮的情况下与显性合子抑制的男性杀手的行动。模拟表明，男性杀手行动的宿主抑制因子可以非常迅速地传播，历史数据表明，最近在东南亚发生的男性杀戮表明，抑制因子的传播是最近发生的。因此，男性杀手/宿主的相互作用比以前认识到的更动态，与表型的快速和戏剧性的损失。我们的研究结果还表明，抑制可以使雄性杀手完全静止，从而得出结论，一些目前不表达雄性杀手的物种可能在过去已经这样做了，因此更多的物种受到这些寄生虫的生物学影响。在东南亚种群中，一种蛱蝶最近进化出了一种合子作用抑制因子，可以防止沃尔巴克氏体寄生虫杀死其雄性后代。
Male-killing bacteria are widespread in arthropods, and can profoundly alter the reproductive biology of their host species. Here we detail the first case of complete suppression of a male killer. The nymphalid butterfly Hypolimnas bolina is infected with a strain of the bacterium Wolbachia, wBol1, which kills male host embryos in Polynesian populations, but does not do so in many areas of Southeast Asia, where both males and female adults are naturally infected, and wBol1-infected females produce a 1:1 sex ratio. We demonstrate that absence of male killing by wBol1 is associated with dominant zygotic suppression of the action of the male killer. Simulations demonstrate host suppressors of male-killer action can spread very rapidly, and historical data indicating the presence of male killing in Southeast Asia in the very recent past suggests suppressor spread has been a very recent occurrence. Thus, male killer/host interactions are much more dynamic than previously recognised, with rapid and dramatic loss of the phenotype. Our results also indicate that suppression can render male killers completely quiescent, leading to the conclusion that some species that do not currently express a male killer may have done so in the past, and thus that more species have had their biology affected by these parasites than previously believed. Within Southeast Asian populations, a nymphalid butterfly has recently evolved a zygotically acting suppressor that prevents the killing of its male offspring by a Wolbachia parasite.
