母系遗传的性比扭曲内共生体如沃尔巴克氏体的流行对生殖和行为有深远的影响,也可以选择昆虫种群中的核抑制因子。在蝴蝶Eurema mandarina中,WolbachiastrainwFem诱导雌性驱力,其中所有后代都发育为雌性,而没有任何兄弟姐妹致命性。我们监测了E的岛屿种群。在2005年至2017年期间,该研究涵盖了wFem阳性女性、wFem阴性女性和wFem阴性男性。尽管有一些波动,wFem似乎保持了至少12年的人口中的高频率,导致女性偏见的人口与相当数量的处女女性。由于没有证据表明存在抑制wFem感染的抑制因子,因此,抑制wFem感染的机制可能是wFem阴性雌虫的不断迁入或wFem的适应度成本。这表明,翅膀的大小略小于inwFem阳性的女性比inwFem阴性的女性。此外,观察到的圈养个体的性别比和性别比之间的差异推断wFem感染的女性之间的频率可以解释为一个塑料的行为变化的男性和女性的性别比的转变。
Prevalence of maternally inherited sex-ratio-distorting endosymbionts such asWolbachiamay have profound effects on reproduction and behaviour and can also select for nuclear suppressors in insect populations. In the butterflyEurema mandarina, aWolbachiastrainwFem induces female drive, wherein all the offspring develop as female without any sibling lethality. We monitored an island population ofE. mandarina, which compriseswFem-positive females,wFem-negative females andwFem-negative males, from 2005 to 2017. Despite some fluctuations,wFem appeared to be maintained for at least 12 years at a high frequency in the population, resulting in a female-biased population with a considerable number of virgin females. Because there was no evidence of suppressors against sex ratio distortion, the mechanism acting against increase/fixation ofwFem infection, which would otherwise lead to the population extinction, would be either the constant immigration ofwFem-negative females or the fitness cost ofwFem. Suggestively, the wing size was slightly smaller inwFem-positive females than inwFem-negative females. Additionally, the discrepancies observed between sex ratios of captive individuals and sex ratios deduced fromwFem infection frequencies among females can be explained by a plastic behavioural change of males and females in response to the shift of sex ratios.
