This paper addresses, what determines that experienced forager honeybees return to places where they have previously exploited nectar. Although there was already some evidence that dance and trophallaxis can cause bees to return to feed, the fraction of unemployed foragers that follow dance or receive food from employed foragers before revisiting the feeder was unknown. We found that 27% of the experienced foragers had no contact with the returning foragers inside the hive. The most common interactions were dance following (64%) and trophallaxis (21%). The great variability found in the amount of interactions suggests that individual bees require different stimulation before changing to the foraging mode. This broad disparity negatively correlated with the number of days after marking at the feeder, a variable that is closely related to the foraging experience, suggesting that a temporal variable might affect the decision-making in reactivated foragers.
本文探讨了是什么决定了有经验的觅食工蜂会回到它们之前采集过花蜜的地方。尽管已经有一些证据表明舞蹈和交哺行为能促使蜜蜂返回进食，但在再次光顾喂食器之前，未就业的觅食工蜂中跟随舞蹈或从就业的觅食工蜂那里获取食物的比例尚不清楚。我们发现，27%的有经验的觅食工蜂在蜂巢内没有与返回的觅食工蜂接触。最常见的互动是跟随舞蹈（64%）和交哺行为（21%）。互动量的巨大差异表明，个体蜜蜂在转变为觅食模式之前需要不同的刺激。这种广泛的差异与在喂食器处标记后的天数呈负相关，这个变量与觅食经验密切相关，这表明一个时间变量可能会影响重新活跃起来的觅食工蜂的决策。
