Sex ratio distortion in the tropical butterfly Acraea encedana is caused by infection with a male-killing bacterium of the genus Wolbachia. Previous research on this species has reported extreme female bias, high bacterial prevalences, and full sex role reversal. In this paper, we provide an assessment for the dynamics of the male-killer, based on a survey for sex ratios and Wolbachia prevalences among wild populations of A. encedana in Uganda. The study reveals that Wolbachia infection showed considerable variation over both spatial and temporal scales.
性比扭曲在热带蝴蝶 Acraea encedana 是由感染一种雄性杀伤细菌属沃尔巴克氏体引起的。以前对这个物种的研究报告了极端的雌性偏见、高细菌流行率和完全的性别角色逆转。在本文中，我们根据对乌干达野生 Acraea encedana 种群的性别比例和沃尔巴克氏体流行率的调查，对雄性杀手的动态进行了评估。研究表明，沃尔巴克氏体感染在空间和时间尺度上都有很大的变化。
