Honeybee navigation
How do bees estimate distance flown? It appears that they use one or both of the following cues. The first comes from measuring the amount of energy consumed when they fly to the destination by the reduction in the volume of their nectar-laden stomachs; the greater the energy consumed, the further the distance. And the second comes from measuring how much the image of the world appears to move ...
متن کاملHoneybee navigation: odometry with monocular input.
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 textured patterns, to collect a reward a...
متن کاملTwo spatial memories for honeybee navigation.
Insect navigation is thought to be based on an egocentric reference system which relates vector information derived from path integration to views of landmarks experienced en route and at the goal. Here we show that honeybees also possess an allocentric form of spatial memory which allows localization of multiple places relative to the intended goal, the hive. The egocentric route memory, which...
متن کاملSHORT COMMUNICATION Guidance by odors in honeybee navigation
Animal navigation is guided by multiple sensory cues. Here, we ask whether and how olfactory stimuli emanating from places other than the trained feeding site redirect the flight paths of honeybees. The flight trajectories of individual bees were registered using harmonic radar tracking. Sensory cues (compass direction, distance, visual cues en route and close to the feeding site) associated wi...
متن کاملHoneybee navigation: following routes using polarized-light cues.
While it is generally accepted that honeybees (Apis mellifera) are capable of using the pattern of polarized light in the sky to navigate to a food source, there is little or no direct behavioural evidence that they actually do so. We have examined whether bees can be trained to find their way through a maze composed of four interconnected tunnels, by using directional information provided by p...
