We studied the spatial and social organization of homospecific and heterospecific colonies of two ant species Manica rubida (Myrmicanae) and Formica selysi (Formicinae) reared without a queen in artificial nests. We used a method based on individual labelling and automated photographic recording of data. The two species, which are forced to live together in the same artificial mixed colony, show the same spatial organization as they do in control homospecific colonies. The Manica rubida were mostly clustered in one chamber while Formica selysi workers were spread throughout the nest. Formica selysi individual spatial profiles are very heterogeneous while in the other species they are very homogeneous. By using taxonomical techniques on behavioural data we show that the two species within the mixed colony are clearly distinguishable. An artificial association of these two species may therefore be considered to be a juxtaposition of two colonies functioning in parallel, rather than a "mixed colony".
我们研究了在人工蚁巢中无蚁王后饲养的两种蚂蚁——红蚁（Myrmicanae亚科的Manica rubida）和赛氏蚁（Formicinae亚科的Formica selysi）的同物种和异物种群体的空间和社会组织。我们采用了基于个体标记和数据自动摄影记录的方法。这两种被迫在同一个人工混合蚁群中共同生活的蚂蚁，其空间组织与对照同物种蚁群中的相同。红蚁大多聚集在一个蚁室中，而赛氏蚁工蚁则分布在整个蚁巢中。赛氏蚁的个体空间分布非常不均匀，而另一种蚂蚁的分布则非常均匀。通过对行为数据运用分类学技术，我们表明混合蚁群中的这两种蚂蚁明显可区分。因此，这两种蚂蚁的人工组合可被视为两个并行运作的蚁群的并置，而非一个“混合蚁群”。
