为了研究蜂群建立过程中的进化和内含体适合度结果，我们开发了52个微卫星座位。大量的基因座很重要，有三个原因可能适用于许多其他系统。我们的目标物种的杂合度很低，但我们发现了足够多的多态座位来进行准确的血缘关系研究。许多单态基因座在其他小蜂中是多态的，这使得比较研究成为可能。最后，在广泛的物种范围内扩增了足够多的基因座，从而增加了历史维度。我们对其他黄蜂的6个基因座进行了测序，并利用侧翼序列构建了系统发育树。基于这一系统发育关系，我们推测蜂群的建立在黄蜂中已经独立进化了三次。
We developed 52 microsatellite loci for the wasp, Polybioides tabidus, for the purpose of studying the evolution and inclusive fitness consequences of swarm‐founding. The large number of loci is important for three reasons that may apply to many other systems. Heterozygosity was low in our target species, yet we found enough polymorphic loci for accurate kinship studies in this species. Many monomorphic loci were polymorphic in other polistine wasps, making comparative studies possible. Finally, enough loci amplified over a broad range of species to add a historical dimension. We sequenced six loci in other polistine wasps and used the flanking sequences to construct a phylogeny. Based on this phylogeny, we infer that swarm‐founding has evolved independently three times in the polistine wasps.
