In this review, we highlight sources of alcohols in nature, as well as the behavioral and ecological roles that these fermentation cues play in the short lifespan of . With a focus on neuroethology, we describe the olfactory detection of alcohol as well as ensuing neural signaling within the brain of the fly. We proceed to explain the plethora of behaviors related to alcohol, including attraction, feeding, and oviposition, as well as general effects on aggression and courtship. All of these behaviors are shaped by physiological state and social contexts. In a comparative perspective, we also discuss inter- and intraspecies differences related to alcohol tolerance and metabolism. Lastly, we provide corollaries with other dipteran and coleopteran insect species that also have olfactory systems attuned to ethanol detection and describe ecological and evolutionary directions for further studies of the natural history of alcohol and the fly.
在这篇综述中，我们强调了自然界中醇类的来源，以及这些发酵线索在 的短暂生命周期中所扮演的行为和生态角色。我们专注于神经行为学，描述了苍蝇大脑中对酒精的嗅觉检测以及随之而来的神经信号。我们接着解释了与酒精相关的大量行为，包括吸引、进食和产卵，以及对攻击和求偶行为的一般影响。所有这些行为都受到生理状态和社会环境的影响。在比较的角度上，我们还讨论了与酒精耐受性和代谢有关的种间和种内差异。最后，我们提供了与其他双翅目和鞘翅目昆虫物种的相关性，这些物种的嗅觉系统也能感知乙醇的检测，并描述了进一步研究酒精和苍蝇自然历史的生态和进化方向。
