Abstract：
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.
CONCLUSIONS: 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.

摘要：
背景：Wolbachia是昆虫中广泛存在的细胞内细菌，由于它们对昆虫繁殖的影响，通常具有很高的传播率。这些细菌还可能影响其宿主的交配行为，并影响宿主后代的适应性。在这项研究中,我们调查了Wolbachia对寄生虫类黄蜂Habrobraconhebetor中与年轻或老年雄性交配的偏好的影响。
结果：我们的结果表明，来自四环素治疗品系的未感染雌性更喜欢与年轻雄性交配，而Wolbachia感染的女性没有偏好。感染品系的交配时间相对较短。不管Wolbachia感染状况如何,与年轻雄性交配产生的后代比与老年雄性杂交产生的后代表现出更高的适应性，受感染的雌性与受感染的年轻雄性杂交表现出最高的表现。
结论：这些结果表明Wolbachia对雌性伴侣偏好和后代适应性有影响，尽管目前尚不清楚这种现象如何增加Wolbachia感染黄蜂的传播。©2024化学工业学会。
