摘要

背景：沃尔巴克氏菌是昆虫中广泛存在的细胞内细菌，由于其对昆虫繁殖的影响，往往具有很高的传播率。这些细菌还可能影响宿主的交配行为，从而影响宿主后代的适应性。在这项研究中，我们调查了沃尔巴克氏菌对寄生蜂 Habrobracon hebetor 与年轻或年老雄性交配偏好的影响：结果表明，来自四环素处理品系的未感染雌性更喜欢与年轻雄性交配，而感染了沃尔巴克氏体的雌性则没有这种偏好。受感染品系的交配时间相对较短。无论沃尔巴克氏体感染状况如何，与年轻雄性交配产生的后代比与年老雄性杂交产生的后代表现出更高的适应性，受感染雌性与受感染年轻雄性杂交产生的后代表现出最高的适应性：这些结果表明了沃尔巴克氏菌对雌性交配偏好和后代适应性的影响，尽管目前还不清楚这种现象是如何增加受感染黄蜂的沃尔巴克氏菌传播的。© 2024 化学工业协会。

Wolbachia affect female mate preference and offspring fitness in a parasitoid wasp.

Background: Wolbachia are widespread intracellular bacteria in insects that often have high rates of spread due to their impact on insect reproduction. These bacteria may also affect the mating behavior of their host with impacts on the fitness of host progeny. In this study, we investigated the impact of Wolbachia on a preference for mating with young or old males in the parasitoid wasp Habrobracon hebetor.

Results: Our results showed that uninfected females from a tetracycline-treated line preferred to mate with young males, whereas Wolbachia-infected females had no preference. Time to mating was relatively shorter in the infected lines. Regardless of Wolbachia infection status, progeny resulting from matings with young males showed higher fitness than those from crosses with old males, and infected females crossed with infected young males showed the highest performance.

Conclusion: These results suggest an impact of Wolbachia on female mate preference and offspring fitness although it is unclear how this phenomenon increases Wolbachia transmission of infected wasps. © 2024 Society of Chemical Industry.
