Honeybees () communicate the direction and distance to a food source by means of a waggle dance. We ask whether bees recruited by the dance use it only as a flying instruction, with the technical form of a polar vector, or also translate it into a location vector that enables them to set courses directed toward the food source from arbitrary locations within their familiar territory. The flights of recruits captured on exiting the hive and released at distant sites were tracked by radar. The recruits performed first a straight flight in approximately the compass direction indicated by the dance. However, this "vector" portion of their flights and the ensuing tortuous "search" portion were strongly and differentially affected by the release site. Searches were biased toward the true location of the food and away from the location specified by translating the origin for the danced polar vector to the release site. We conclude that by following the dance recruits get two messages, a polar flying instruction (bearing and range from the hive) and a location vector that enables them to approach the source from anywhere in their familiar territory. The dance communication is much richer than thought so far.
蜜蜂通过摇摆舞来传达食物源的方向和距离。我们想知道,被舞蹈招募的蜜蜂是否只将其用作飞行指令,采用极向量的技术形式,或者也将其转化为位置向量,从而使它们能够从熟悉的领地内的任意位置设定指向食物源的航向。通过雷达追踪出巢后被招募者的飞行轨迹,它们在远离巢穴的地点被释放。被招募者在最初的飞行中沿着舞蹈指示的大致罗盘方向进行直线飞行。然而,他们的飞行的“向量”部分以及随后的曲折的“搜索”部分受到释放地点的强烈和不同的影响。搜索偏向于食物的真实位置,而不是将跳舞的极向量原点转换到释放地点所指定的位置。我们得出结论,通过跟随舞蹈,被招募者可以获得两条信息,一条是飞行的极向量指令(从蜂巢到目的地的方位和距离),另一条是位置向量,使它们能够从熟悉的领地内的任何位置接近食物源。舞蹈的信息传递比目前为止人们想象的要丰富得多。
