Recent studies have revealed that navigating honeybees, Apis mellifera, estimate the distance to a food source by integrating over time the image motion that they experience en route. Here we examine the ability of honeybees to gauge distance travelled when visual input is available primarily to one eye. Bees were trained to fly into a tunnel, lined with… CONTINUE READING
Figure 1. General layout of training and test situations. Bees, trained to find a food reward (circle) placed at a specific location in a training tunnel (a), were subsequently tested in two situations. In the ‘food-search test’ (b), the trained bees encountered a fresh tunnel identical to the training tunnel, which carried no reward. In the ‘homing test’ (c), the reward was retained, as in the training situation, but an extension was apposed to the entrance of the original training tunnel after a bee had alighted on the feeder. In either case, the behaviour of the bee as it searched for the feeder (food-search test) or for the tunnel exit (homing test) was recorded and analysed as described in the General Methods.
