食物是许多动物物种生长和发育进程的有限资源。因此，对食物、空间或其他资源的竞争可能会引发领土和攻击性行为。在帝王蝶Danaus plexippus中，毛虫主要以马利筋为食，这增加了获取马利筋对生长和生存至关重要的可能性。在这里，我们描述了食物供应对帝王毛虫攻击性的作用，发现帝王毛虫表现出刻板的攻击性突起，在发育过程中增加，在四龄和五龄阶段达到顶峰。在食物可获得性低的情况下，向同种毛虫猛扑的次数显著增加，这表明资源防御可能会引发攻击。这些发现建立了帝王毛虫作为研究生态相关条件下资源可获得性与攻击行为之间相互作用的模型，并为未来研究该系统中攻击行为的神经行为学奠定了基础。帝王毛虫表现出刻板印象的攻击性行为攻击是由有限的食物供应引发的攻击行为在毛虫发育的后期达到顶峰生物科学；昆虫学；行为神经科学
Food represents a limiting resource for the growth and developmental progression of many animal species. As a consequence, competition over food, space, or other resources can trigger territoriality and aggressive behavior. In the monarch butterfly, Danaus plexippus, caterpillars feed predominantly on milkweed, raising the possibility that access to milkweed is critical for growth and survival. Here, we characterize the role of food availability on aggression in monarch caterpillars and find that monarch caterpillars display stereotyped aggressive lunges that increase during development, peaking during the fourth and fifth instar stages. The number of lunges toward a conspecific caterpillar was significantly increased under conditions of low food availability, suggesting resource defense may trigger aggression. These findings establish monarch caterpillars as a model for investigating interactions between resource availability and aggressive behavior under ecologically relevant conditions and set the stage for future investigations into the neuroethology of aggression in this system.
