The ability of freely-flying honeybees to track moving targets was cxaminend.The results show that bees are perfectly capable of tracking moving targets and landing on them. When the distance of the target is greater than ca. 15 cm, approaching bees correct for angular deviations of the target from the midline, both in the horizontal and in the vertical plane. In either plane, the input variables that are important to the tracking system seem to be (i) the angular bearing of the target with respect to the midline, and (ii) the angular velocity of the target with respect to the eye, The control system tends to orient the bee such that the target is located frontly, at an angle of ca.40 deg below the equator.The choromatic properties of tracking behaviour were investigated. The results of these experiments suggest that; in contolling tracking, the measurement of the angular velocity of the target is derived almost exclusively from the green-sensitive receptors, as is the case with previously btudied movement-sensitive behaviours. However; the measurement of the angular bearing of the target is derived from the blue-sensitive receptors as well as the green-sensitive ones.When the target distance is lower than ca.15 cm, approaching bees use translational manoeuvres, in addition to rotational ones; track the moving target. Translational target tracking appears to be driven primarily by signals from the green-sensitive receptors.

本文对自由飞行蜜蜂跟踪运动目标的能力进行了研究.实验结果表明蜜蜂能够准备地跟踪运动目标.当目标的距离较大时蜜蜂主要通过校正与目标的角度偏差接近目标.无论是在水平方向或是垂直方向,密蜂使用了目标误差角以及目标相对蜜蜂的角速度的信息.蜜蜂的运动目标跟踪控制系统,往往把目标置于复眼的前下方体轴夹角约35度的视场区域中.目标与背景颜色对(?)的的实验结果表明蜜蜂跟踪行为所利用的目标的速度的信息是来自于对绿色敏感的光感受器:而与目标位置有关的方位角的信息则不仅仅来自于绿色光感受器,而且也来自于兰色光感受器.当蜜蜂与目标的距离较近时,蜜蜂除了角度校正以外还使用了横向移动来跟踪运动目标.横向目标跟踪系统看来仅仅接受来自于对绿色敏感的光感受器的信号.
