福建农林大学苏松坤、Martin Giurfa研究团队合作表明，食物需求是由蜜蜂大脑中多巴胺信号的短暂激活介导的。2022年4月29日，国际知名学术期刊《科学》发表了这一成果。

在这项研究中，他们专注于蜜蜂，它们进行密集的觅食活动以满足蜂群的需求，并试图确定觅食者是否会因对奖励的特定期望而离开蜂巢，以及它们是否在摇摆舞中回忆起这些期望。他们监测觅食和舞蹈行为，同时量化和干扰蜜蜂大脑中的生物胺信号。

他们表明，通过增加食欲和对获益食物来源的个体回忆，在前往目标的途中和摇摆舞过程中，蜜蜂大脑中的多巴胺依赖性需求系统被短暂激活。他们的研究结果表明，昆虫与哺乳动物共享共同的神经机制，用于编码具有正享乐价值刺激的需求。

据了解，哺乳动物需求生物学基础已经被表征，但昆虫是否也存在类似的需求系统仍不清楚。

Abstract: The biological bases of wanting have been characterized in mammals, but whether an equivalent wanting system exists in insects remains unknown. In this study, we focused on honey bees, which perform intensive foraging activities to satisfy colony needs, and sought to determine whether foragers leave the hive driven by specific expectations about reward and whether they recollect these expectations during their waggle dances. We monitored foraging and dance behavior and simultaneously quantified and interfered with biogenic amine signaling in the bee brain. We show that a dopamine-dependent wanting system is activated transiently in the bee brain by increased appetite and individual recollection of profitable food sources, both en route to the goal and during waggle dances. Our results show that insects share with mammals common neural mechanisms for encoding wanting of stimuli with positive hedonic value.
