为了研究熊蜂之间的相互作用是否会减少它们的觅食面积，我们在网箱中进行了蜜蜂去除实验。在笼子里，我们设置盆栽鼠尾草植物，让熊蜂在这些植物上自由觅食，并跟随它们的植物到植物的运动，以识别觅食面积相对较小的蜜蜂。然后将其他觅食蜂全部剔除，只留下觅食面积较小的蜂，观察焦点蜂在不与其他蜂相互作用的条件下觅食面积的变化。在移除其他蜜蜂后，所有五只蜜蜂都扩大了它们的觅食区域，这表明蜜蜂之间的相互作用是它们觅食区域的重要决定因素。这一结果也意味着大黄蜂能够根据其他觅食者的反应调整自己的觅食区域。这表明未来的研究有必要澄清蜜蜂使用什么线索与其他蜜蜂互动。此外，在去除处理后，所有五只蜜蜂都表现出每株植物花探针数量的暂时增加。这可以解释为他们的最佳觅食根据“旧”的平均摄入率的植物种群和延迟的变化，以响应“新”的高平均能量摄入率后，蜜蜂去除治疗。
To examine whether the interaction between bumblebees, Bombus ignitus, reduces their foraging area, we conducted bee-removal experiments in a net cage. In the cage, we set potted Salvia farinacea plants, allowed bumblebees to forage freely on those plants, and followed their plant-to-plant movements to identify a bee with a relatively small foraging area. We then removed all the other foraging bees, except for the bee with a small foraging area, and observed the change of the foraging area of the focal bee under conditions of no interaction with other bees. After the removal of the other bees, all five bees tested enlarged their foraging areas, suggesting that the interaction between bees is an important determinant of their foraging areas. The result also means that bumblebees are able to adjust their foraging areas in response to other foragers. indicating the necessity for future studies to clarify what cues bees use to interact with other bees. Moreover, after the removal treatments, all five bees showed temporary increases in the number of flower probes per plant. This can be explained by their optimal foraging according to the "old" average intake rate for the plant population and by the delayed changes in response to the "new" high average energy intake rate after the bee-removal treatments.
