蜜蜂（Apis melliferaL.）通过蜂群繁殖，蜂王带着大约三分之二的工蜂（主要蜂群）离开巢穴。在最初的巢中养育了几个女儿蚁后，在第一批蜂群离开后不久就开始出现。其中一个或几个后代蜂王可能会带着较小的后蜂群依次离开原来的蜂群。在这里，我们研究了自由飞行的蜜蜂群体繁殖后对前巢同伴的接受度的变化。我们总共使用了4个蜂群，每个蜂群被分成4个新蜂群：2个人工蜂群（后代蜂群）和2个模仿已建立的蜂群（“旧”蜂群）的蜂群。原始（母）菌落的划分方式使我们能够确定蜡梳在线索分化中的相对重要性。一半的蜂群有母蜂群的原始蜡梳，而其他的蜂群没有提供梳子，需要他们自己建造。然后，我们通过在蜂巢入口引入觅食者并观察守卫蜜蜂的行为来测试前巢友的接受程度。我们的研究结果并没有显示出在蜂群之后对前巢友的接受度有一致的变化。在四分之二的重复中，来自含有原始蜡梳子的蜂群的工蜂被来自最初没有梳子的蜂群的警卫拒绝。这表明蜂蜡在识别配偶方面起着重要作用。然而，剩下的两个重复没有显示出反应；在人工群集两周后，所有以前的同伴仍然被接受。
Honey bees (Apis melliferaL.) reproduce by swarming wherein the mother queen leaves the nest with approximately two thirds of her workers (the prime swarm). Several daughter queens are raised in the original nest, and these start to emerge shortly after the first swarm departs. One or several of these daughter queens may then leave the original colony sequentially with smaller afterswarms. Here we study the change in acceptance of former nestmates after colony reproduction using free-flying honey bee colonies. We used a total of four colonies each of which we divided to make four new colonies: two artificial swarms (the offspring colonies) and two colonies that mimic established ('old') colonies after swarming. The way the original (mother) colonies were divided allowed us to determine the relative importance of wax comb on cue divergence. Half of the divisions contained the original wax combs from the mother colony whereas the other divisions were not provided with comb requiring them to construct their own. We then tested the acceptance of former nestmates by introducing foragers at the hive entrances and observing the behaviour of guard bees. Our results did not show a consistent change in acceptance of former nestmates after swarming. In two out of four replicates, workers originating from the colonies that contained the original wax combs were rejected by guards from the initially comb-less colonies. This suggests that comb wax plays an important role in nestmate recognition. However, the remaining two replicates did not show a response; all former nesmates were still accepted two weeks after artificial swarming.
