Abstract

In this review, we explore the social behavior of the fruit fly Drosophila melanogaster, integrating mechanistic, ecological and evolutionary perspectives. Despite its status as a major laboratory model organism, D. melanogaster’s social life remains generally underappreciated by biologists. Adult flies attract others to food sources through pheromone deposition, leading to group formation. Within these groups, males engage in competitive reproductive behaviors while females adopt complex mating patterns and lay eggs communally. Both sexes adapt their reproductive behaviors to early as well as current social experience. Communal egg-laying by females promotes larval group formation, with larvae cooperating to dig tunnels for protection and breathing while feeding. Aggregation is also visible at the pupal stage, suggesting a social dimension to the entire life cycle of this species. We examine the competitive and cooperative behaviors of D. melanogaster, considering the ecological context (resource distribution, predation, parasitism pressures, and reproductive strategies) that influences these social interactions. We also discuss how individual behavior and physiology varies with group size and diversity, potentially as an adaptation to the costs and benefits of being in a group. This review underscores the potential of fruit flies in advancing research on social interactions and dynamics, demonstrating their usefulness for the fields of sociality, evolution and social neurosciences.

黑腹果蝇的社会生活
在这篇综述中,我们从机理、生态学和进化论的角度探讨了黑腹果蝇的社会行为。尽管黑腹果蝇是主要的实验室模式生物,但生物学家对其社会生活的认识普遍不足。成蝇通过信息素沉积将其他蝇类吸引到食物源,从而形成群体。在这些群体中,雄蝇进行竞争性生殖行为,而雌蝇则采用复杂的交配模式,并共同产卵。雌雄蝇都会根据早期和当前的社会经验调整自己的生殖行为。雌性的集体产卵促进了幼虫群体的形成,幼虫在觅食时会合作挖掘隧道以提供保护和呼吸。在蛹的阶段也可以看到聚集行为,这表明该物种的整个生命周期都具有社会性。我们研究了黑腹蝇蛆的竞争与合作行为,考虑了影响这些社会互动的生态环境(资源分布、捕食、寄生压力和繁殖策略)。我们还讨论了个体行为和生理如何随群体大小和多样性而变化,这可能是对群体中的成本和收益的一种适应。这篇综述强调了果蝇在推动社会互动和动态研究方面的潜力,证明了它们对社会性、进化和社会神经科学领域的有用性。

期刊介绍: Insectes Sociaux (IS) is the journal of the International Union for the Study of Social Insects (IUSSI). It covers the various aspects of the biology and evolution of social insects and other presocial arthropods; these include ecology, ethology, morphology, population genetics, reproduction, communication, sociobiology, caste differentiation and social parasitism. The journal publishes original research papers and reviews, as well as short communications. An international editorial board of eminent specialists attests to the high quality of Insectes Sociaux, a forum for all scientists and readers interested in the study of social insects.
