Abstract

Oil bees, which gather oil from flowers, transfer the floral oil collected from fore-legs, to middle-legs, and then to hind-legs, where they store the oil until release in the nest's brood cell. The complex leg maneuvers and the specialized hair types according to their location and function on the legs have been described in the past using morphological observations and in vivo behavioral monitoring, sometimes during flight. The aim of this work is to describe the different steps of oil transfer and to infer the role of the different hair types using a manipulative approach on isolated legs, controlled amounts of oil and high speed video recordings. A rapid and uni-directional capillary oil movement from the collecting ventral side of tarsi and/or tibiae to their dorsal side is observed in each fore-, middle-, and hind-legs. This suggests that plumose setae and pluridentate setae present different functionalities, acting either as oil donors or receptors, depending on their location on the legs. In the transfers observed, very little oil remains on the donor surface, so that a bee collecting oil from flower can quickly replenish the donor surface again.

油蜂腿内和腿间的油脂转移。
油蜂从花朵中收集油,将收集到的花油从前肢转移到中肢,然后转移到后腿,在那里储存油,直到释放到巢的孵化室。复杂的腿部动作和根据它们在腿上的位置和功能而特殊的毛发类型在过去已经通过形态学观察和在体行为监测来描述,有时在飞行中。这项工作的目的是描述油转移的不同步骤,并通过对孤立的腿,控制油量和高速录像的操作方法来推断不同头发类型的作用。在前、中、后腿均观察到从跗骨和(或)胫骨集合腹侧到其背侧的快速单向毛细血管油运动。这表明刚毛和多毛刚毛具有不同的功能,取决于它们在腿上的位置,它们要么是供油者,要么是受体。在观察到的转移过程中,很少有油留在供体表面,因此蜜蜂从花上收集油可以迅速补充供体表面。
