一些脊椎动物表现出复杂的数字概念，包括加法，数字的顺序，甚至零的概念，但昆虫是否能理解这些概念仍然是未知的。我们使用包含一到六个元素特征的刺激来训练个体蜜蜂的“大于”或“小于”的数字概念。蜜蜂可以随后推断的概念小于零数量级的低端的数值连续。蜜蜂表现出的理解力与非洲灰鹦鹉、非人类灵长类动物甚至学龄前儿童等动物相似。
Some vertebrates demonstrate complex numerosity concepts-including addition, sequential ordering of numbers, or even the concept of zero but whether an insect can develop an understanding for such concepts remains unknown. We trained individual honey bees to the numerical concepts of "greater than' or "less than" using stimuli containing one to six elemental features. Bees could subsequently extrapolate the concept of less than to order zero numerosity at the lower end of the numerical continuum. Bees demonstrated an understanding that parallels animals such as the African grey parrot, nonhuman primates, and even preschool children.
