一只受约束的蜜蜂可以通过训练来延长它的喙，以回应与蔗糖奖励配对的气味，这是一种嗅觉联想学习的形式，被称为喙延伸反应（PER）。虽然飞行蜜蜂对视觉线索的反应能力是公认的，但在受约束的蜜蜂中证明联想视觉学习是具有挑战性的。那些记录了基于视觉的PER的少数小组报告说，在训练之前去除天线是学习的先决条件。在这里，我们报告了一个简单的视觉学习任务，第一次成功的表现约束蜜蜂完整的触角。蜜蜂觅食者接受了一项不同视觉联想任务的训练，方法是将蓝光与蔗糖奖励配对，而不奖励绿光。发现觅食者的年龄与他们在视觉PER任务中的表现呈负相关。利用对传统PER任务的适应，未来的研究可以利用药理学和生理学技术来探索蜜蜂视觉学习的神经回路基础。
A restrained honey bee can be trained to extend its proboscis in response to the pairing of an odor with a sucrose reward, a form of olfactory associative learning referred to as the proboscis extension response (PER). Although the ability of flying honey bees to respond to visual cues is well-established, associative visual learning in restrained honey bees has been challenging to demonstrate. Those few groups that have documented vision-based PER have reported that removing the antennae prior to training is a prerequisite for learning. Here we report, for a simple visual learning task, the first successful performance by restrained honey bees with intact antennae. Honey bee foragers were trained on a differential visual association task by pairing the presentation of a blue light with a sucrose reward and leaving the presentation of a green light unrewarded. A negative correlation was found between age of foragers and their performance in the visual PER task. Using the adaptations to the traditional PER task outlined here, future studies can exploit pharmacological and physiological techniques to explore the neural circuit basis of visual learning in the honey bee.
