Social immunization (SI) is a horizontal transfer of immunity that protects naive hosts against infection following exposure to infected nestmates. While mainly documented in eusocial insects, non-social species also share similar ecological features which favour the development of group-level immunity. Here, we investigate SI in by pairing naive females with a pathogen-challenged conspecific for 72 h before measuring a series of immune and fitness traits. We found no evidence for SI, as beetles who cohabited with a live pathogen-challenged conspecific were not better protected against bacterial challenge. However, exposure to a heat-killed-bacteria-challenged conspecific appeared to increase pathogen tolerance, which manifested in differential fitness investment. Our results together suggest that do respond to immune-related cues in the social environment, despite not showing a classic immunization response as predicted.
社会免疫（SI）是一种水平免疫转移，可保护初次接触感染巢伴的天真宿主免受感染。虽然主要在真社会性昆虫中得到证实，但非社会性物种也具有相似的生态特征，有利于群体水平免疫的发展。在这里，我们通过将天真的雌性与同种受病原体挑战的个体配对 72 小时，然后测量一系列免疫和适应性特征，来研究 的 SI。我们没有发现 SI 的证据，因为与活病原体挑战的同种个体同居的甲虫并没有更好地免受细菌挑战的保护。然而，暴露于热杀死细菌挑战的同种个体似乎增加了对病原体的耐受性，这表现在不同的适应性投资上。我们的研究结果表明，尽管 没有表现出预期的经典免疫反应，但它们确实对社会环境中的免疫相关线索做出了反应。
