1.在自然界中,宿主从出生到老年,面临着寄生虫暴露和生活史权衡的变化模式。因此,免疫投资的净健身效益可以从一个生命阶段到下一个阶段发生巨大变化。先前的工作揭示了幼年和成年阶段之间相对免疫投资模式的令人困惑的多样性,并且在考虑了局部适应和其他方差产生过程之后,尚不清楚从一个特定种群或物种中吸取的经验教训是否可以推广到野生种群。在这项研究中,我们量化了来自七个野生种群的两种面粉甲虫物种(赤拟谷盗和杂拟谷盗)的幼虫和成虫免疫基因表达以及对细菌感染的抗性。我们的研究结果提供了一个明确的信号,即相对于幼虫,成虫中感染诱导的免疫投资和抗性更高,尽管免疫基因调控在物种之间存在差异。更好地描述自然群体中感染抗性的阶段特异性投资可以为我们了解生命史进化提供信息,并改善对野生疾病动态的预测。
1. In nature, hosts face shifting patterns of parasite exposure and life history trade‐offs, as they develop from birth to old age. As a result, the net fitness benefit of immunological investment can change dramatically from one life stage to the next.2. Previous work has revealed a puzzling diversity of relative immune investment patterns among juvenile and adult stages, and it is not clear whether lessons learned from one particular population or species can be generalised to wild populations, after accounting for local adaptation and other variance‐generating processes.3. In this study, we quantify larval and adult immune gene expression and resistance to bacterial infection in two flour beetle species (Tribolium castaneumandTribolium confusum) from seven wild‐derived populations.4. Our results provide a clear signal of higher infection‐induced immunological investment and resistance in adults relative to larvae, despite variation among species in immune gene regulation.5. Better characterisation of stage‐specific investment in infection resistance in natural populations can inform our understanding of life history evolution and improve predictions of disease dynamics in the wild.
