1.对蜜蚁myrmecocystus mimicusus的实地研究表明，蜂群通常由2-9只雌蜂组成，最常见的是2-4只雌蜂。筑巢巢也聚集在一块一块的，远离现有的m。minicuscolonies.2。实验室实验表明，蜂群的建立涉及到蜂群间的突袭：来自相邻早期蜂群的幼鸟由工蜂从一个巢穴运送到另一个巢穴。最终，所有的幼鸟都住在一个单独的巢室里，工蜂把它当作自己的。工蜂们经常抛弃它们的母亲而去筑巢。我们的结论是，筑巢巢之间的竞争有利于筑巢者协会，而群体间的袭击是聚集的多效性筑巢巢的自然结果。发展了一个关于创始协会演变的一般理论，它描述了创始协会将受到青睐的条件。研究表明，特定规模的创始群体的进化取决于群体生产力函数的形状。增加创始人之间的相关性通常会导致更大的最佳创始人群体规模。在实验室中收集了不同规模的铸造机组的生产数据。Mimicusare使用开发的理论进行分析。结果表明，根据该理论所期望的创始关联的大小与自然界中观察到的值非常接近。
1.Field studies of the honey antMyrmecocystus mimicushave revealed that colonies are often founded by groups of foundresses ranging in size from 2–9 females, with groups of 2–4 females being most common. Founding nests are also aggregated together in patches which are distant from existingM. minicuscolonies.2.Laboratory experiments have shown that colony founding involves inter-colony raiding: the brood from neighboring incipient colonies is transported by workers from one nest to another. Ultimately all of the brood ends up in a single nest chamber which the workers adopt as their own. Workers frequently abandon their mothers in favor of these nests. We conclude that competition among founding nests favors foundress associations and that inter-colony raiding is a natural consequence of aggregated pleometrotic founding nests.3.A general theory of the evolution of foundress associations is developed which describes the conditions under which foundress associations will be favored. It is shown that the evolution of foundress groups of particular sizes depends on the shape of the colony productivity function. Increasing relatedness among foundresses will generally result in a larger optimum foundress group size. Production data on foundress groups of different sizes gathered in the laboratory onM. mimicusare analyzed using the theory developed. It is shown that the size of foundress associations expected on the basis of the theory is very near the value observed in nature.
