营养可以对社会行为产生深远的影响，包括个人之间的攻击性互动。流行的理论和经验理解是，当营养资源有限时，个体间的竞争和侵略性会增加。另一方面，对一些群居物种的研究表明，有限的营养可以导致合作的增加，包括减少个体间的攻击。因此，在本发明中，理解营养资源限制如何以及为什么会影响攻击行为的一般模型仍然难以捉摸。我们认为，营养和未来生殖潜力之间的联系可能是预测营养资源可用性如何影响社会动物个体间攻击的模型的关键缺失元素。我们研究了营养如何影响群体内攻击及其分子相关性。黄蜂Polistes fuscatus，其中包含保持灵活的繁殖潜力作为成年工人。我们将菌落进行高或低喂养处理，并检查随后对行为，营养/生殖生理学和大脑基因表达的影响。我们发现，营养限制减少侵略性的相互作用。因此，资源限制与减少组内冲突有关。因此，单个工蜂似乎有能力调整自己的行为（例如，减少攻击性）对营养压力的反应;这表明它们可能在资源有限时将营养资源投入殖民地，在自我中，（以及未来可能的繁殖）。大脑基因表达差异结果涉及两种与攻击性和/或攻击性相关的众所周知的神经肽。或跨类群的营养信号传导，速激肽和神经肽F，作为营养依赖性群体内攻击的可能介质。这增加了一个日益增长的理解，即与核心相关的高度保守的基因，保守的行为，如独居昆虫的进食和攻击，可以在更高度社会化的物种中发挥社会可塑性的调节作用。
Nourishment can have profound effects on social behaviour, including aggressive interactions between individuals. The prevailing theoretical and empirical understanding is that when nutritional resources are limited, inter‐individual competition and aggression will increase. Alternatively, studies from some group‐living species suggest limited nutrition can lead to increased cooperation, including by a reduction in inter‐individual aggression. Thus, a general model for understanding how and why nutritional resource limitation affects aggressive behaviour remains elusive.We suggest that the link between nourishment and future reproductive potential may be a key missing element of models that predict how nutritional resource availability affects inter‐individual aggression in social animals.We investigated how nourishment influenced intra‐colony aggression and its molecular correlates in colonies of the social paper waspPolistes fuscatus, which contain workers that maintain flexible reproductive potential as adults. We subjected colonies to either a high or low feeding treatment, and examined subsequent effects on behaviour, nutritional/reproductive physiology and brain gene expression.We found that nutritional restriction reduced aggressive interactions. Thus, resource limitation was linked to reduced intra‐group conflict. Thus, individual worker paper wasps appear to have the capacity to adjust their behaviour (e.g. reduced aggression) in response to nutritional stress; this suggests they may invest nutritional resources in the colony when resources are limiting, and in the self (and possible future reproduction) when resources are abundant.Differential brain gene expression results implicate two well‐known neuropeptides associated with aggression and/or nutrient signalling across taxa,TachykininandNeuropeptide F, as possible mediators of nutritionally dependent intra‐colony aggression. This adds to a growing understanding that deeply conserved genes associated with core, conserved behaviours such as feeding and aggression in solitary insects can play a role in the regulation of social plasticity in more highly social species.A free Plain Language Summary can be found within the Supporting Information of this article.
