The interplay between the recruitment dance and food-giving trophallactic contacts of returning Apis meellifera foragers was analyzed. Dancing and trophallactic events were recorded for bees returning from a rate feeder that provided 50% weight on weight sucrose solution at a constant flow rate of 5 microl min(-1). Bees that had danced immediately before their trophallactic contact had more recipients per trophallaxis compared with bees that did not dance before. Thus, besides information coded in dancing behavior, dance maneuvers could serve as a stimulus to increase attention of bees located on the dance floor to receive nectar. In addition, the number of bees receiving food during a trophallaxis showed a positive correlation with the probability of dancing immediately after contacting. The time from arrival at the hive to when the first or the subsequent contacts took place presented no correlation with the probability of dancing after trophallaxis. Also, the duration of a trophallaxis was positively correlated with the number of recipients per trophallaxis. These results suggest that returning foragers could receive information during a trophallactic contact with their hive mates that modify thresholds for dancing. Dance maneuvers and trophallactic contacts performed by foraging bees seem to be "mutually" affected.
对归来的意大利蜜蜂觅食者的招募舞蹈与给予食物的交哺接触之间的相互作用进行了分析。记录了从一个速率饲喂器归来的蜜蜂的舞蹈和交哺事件，该饲喂器以5微升/分钟的恒定流速提供重量比为50%的蔗糖溶液。与交哺接触前未跳舞的蜜蜂相比，在交哺接触前立即跳舞的蜜蜂每次交哺有更多的接受者。因此，除了舞蹈行为中编码的信息外，舞蹈动作还可以作为一种刺激，提高位于舞场上的蜜蜂接受花蜜的注意力。此外，在一次交哺期间接受食物的蜜蜂数量与交哺后立即跳舞的概率呈正相关。从到达蜂巢到首次或随后接触发生的时间与交哺后跳舞的概率没有相关性。同样，一次交哺的持续时间与每次交哺的接受者数量呈正相关。这些结果表明，归来的觅食者在与蜂巢同伴的交哺接触过程中可能会接收到改变跳舞阈值的信息。觅食蜜蜂进行的舞蹈动作和交哺接触似乎相互影响。
