催产素/加压素相关的神经肽是高度保守的，并在调节脊椎动物的社会行为中发挥重要作用。然而，他们的昆虫直系同源物，inotocin，是否调节社会群体的行为仍然未知。在这里，我们表明，在克隆袭击者蚂蚁Ooceraea biroi，在巢外执行任务的个人有更高水平的催产素在他们的大脑比同一年龄的个人留在巢内。我们还发现，年龄较大的蚂蚁，花更多的时间在巢外，有较高的催产素水平比年轻的蚂蚁。因此，催产素与在巢外执行任务的倾向相关。此外，增加催产素的含量会增加蚂蚁离开巢穴的倾向。然而，这种影响取决于年龄和社会背景。经过药物治疗的老年蚂蚁只有在幼虫存在的情况下才有更高的离开巢穴的倾向，而年轻的蚂蚁似乎只有在蛹存在的情况下才这样做。我们的研究结果表明，催产素信号在调节与年龄相关的行为中起着重要的作用，如社会觅食，可能是通过调节特定社会线索的行为反应阈值。因此，催产素信号可能有助于蚂蚁社会中的行为个性和劳动分工。神经肽催产素和加压素调节脊椎动物的社会行为，但它们在无脊椎动物中的功能还不清楚。利用大脑染色和药理学操作，这项研究表明，一种相关的神经肽，催产素，影响蚂蚁如何对幼虫作出反应。
Oxytocin/vasopressin-related neuropeptides are highly conserved and play major roles in regulating social behavior across vertebrates. However, whether their insect orthologue, inotocin, regulates the behavior of social groups remains unknown. Here, we show that in the clonal raider ant Ooceraea biroi, individuals that perform tasks outside the nest have higher levels of inotocin in their brains than individuals of the same age that remain inside the nest. We also show that older ants, which spend more time outside the nest, have higher inotocin levels than younger ants. Inotocin thus correlates with the propensity to perform tasks outside the nest. Additionally, increasing inotocin pharmacologically increases the tendency of ants to leave the nest. However, this effect is contingent on age and social context. Pharmacologically treated older ants have a higher propensity to leave the nest only in the presence of larvae, whereas younger ants seem to do so only in the presence of pupae. Our results suggest that inotocin signaling plays an important role in modulating behaviors that correlate with age, such as social foraging, possibly by modulating behavioral response thresholds to specific social cues. Inotocin signaling thereby likely contributes to behavioral individuality and division of labor in ant societies. The neuropeptides oxytocin and vasopressin modulate social behavior in vertebrates, but their function in invertebrates is not well understood. Using brain staining and pharmacological manipulations, this study shows that a related neuropeptide, inotocin, affects how ants respond to larvae.
