长途飞行寻找有价值的花朵并返回家园的能力是蜜蜂（Apis mellifera）生存的关键因素。为了可靠地执行此任务，蜜蜂结合了里程计和地标线索，这可能会造成困境，因为富含里程计线索的环境可能缺乏显着的地标线索，反之亦然。在本研究中，蜜蜂对复杂自然场景的图像进行了差异调节，以确定它们是否能够可靠地学会区分非常相似的场景，并从新颖的干扰场景中识别出学习到的场景。个体蜜蜂做出的选择是用信号检测理论建模的，尽管图像的时空内容相似，但蜜蜂表现出了区分感知相似的目标视图和干扰视图的能力。在无奖励转移测试中，蜜蜂也能够从新的干扰物中识别出目标刺激。这些发现表明，蜜蜂的视觉处理足够准确，可以将复杂的风景识别为潜在的地标，这将使在森林中飞行的蜜蜂能够使用树木作为地标和/或里程提示。
The ability to navigate long distances to find rewarding flowers and return home is a key factor in the survival of honeybees ( Apis mellifera). To reliably perform this task, bees combine both odometric and landmark cues, which potentially creates a dilemma since environments rich in odometric cues might be poor in salient landmark cues, and vice versa. In the present study, honeybees were provided with differential conditioning to images of complex natural scenes, in order to determine if they could reliably learn to discriminate between very similar scenes, and to recognise a learnt scene from a novel distractor scene. Choices made by individual bees were modelled with signal detection theory, and bees demonstrated an ability to discriminate between perceptually similar target and distractor views despite similar spatiotemporal content of the images. In a non-rewarded transfer test bees were also able to recognise target stimuli from novel distractors. These findings indicate that visual processing in bees is sufficiently accurate for recognising views of complex scenery as potential landmarks, which would enable bees flying in a forest to use trees both as landmark and/or odometric cues.
