蚂蚁具有非常多样化的饮食和非凡的物种丰富，使它们成为研究味道进化的极佳模型系统。在这个完全是社会性的分支中，食物选择和调节进食的机制既有个人层面的，也有社会层面的。味觉感受器和感觉处理是如何驱动蚂蚁的食物偏好产生饮食广度的，目前还知之甚少。此外，还不清楚群体组织的要素，如劳动分工和社会食物流动如何影响口味的机制基础和进化。以前关于双翅目、鳞翅目和膜翅目味觉系统的工作，虽然是基础性的，但对蚂蚁饮食的专业化提供了有限的见解。在这里，我们综合和分析关于蚂蚁味觉的研究，以确定机制、社会生物学相关性和系统发育模式。我们讨论了味觉基因组分析的现状和未来的研究。我们认为，Pheidole、Cephalotes、Camponotus和切叶蚂蚁(Atta和Acromyrmex)的显著多态物种提供了令人信服的社会系统来探索味觉的适应性变异，因为它们具有明显的分工，在形态、行为和神经分化的工蚁取食行为上存在差异。对蚂蚁味觉在物种内和物种间的研究将促进我们对感官系统的理解，并提供对味觉对物种多样性进化的影响以及社会组织如何影响味觉的洞察。
Ants have remarkably diverse diets and extraordinary species richness, making them an excellent model system to study the evolution of taste. In this entirely eusocial clade, food choice and the mechanisms that regulate feeding have both individual and social dimensions. How taste receptors and sensory processing drive food preferences to generate dietary breadth in ants is poorly understood. It is additionally unclear how elements of colony organization such as division of labor and social food flow impact the mechanistic basis and evolution of taste. Previous work on dipteran, lepidopteran, and hymenopteran gustatory systems, while foundational, provide limited insights into ant dietary specialization. Here we synthesize and analyze research on ant gustation to identify mechanisms, sociobiological correlates, and phylogenetic patterns. We discuss the current state of genomic analyses of taste and future research. We propose that strikingly polymorphic species of Pheidole, Cephalotes, Camponotus, and leafcutter ants (Atta and Acromyrmex) offer compelling social systems to explore adaptive variation in gustation because of their pronounced division of labor in which morphologically, behaviorally, and neurally differentiated workers vary in feeding behavior. Research on ant gustation within and among species will advance our understanding of sensory systems and provide insight into the impact of taste on the evolution of species diversity and how social organization influences gustation.
