Evolution of satellite-nest building in Polistinae

对巴西独立创建的黄蜂Polistes Satan的群体遗传结构进行了研究。丰水期群体的繁殖雌性数显著多于枯水期群体，因此各发育阶段的亲缘关系也低于枯水期群体。在旱季和雨季，连续队列组之间的基因频率明显不同，表明该物种表现出一系列的一夫多妻制。P.撒旦建造卫星巢，但建造行为可能与解决优势生殖雌性之间的冲突无关。

Colony genetic structures were examined in a Brazilian independent-founding wasp Polistes satan. The number of reproductive females was significantly larger in colonies of wet season than in colonies of dry season, and consequently the relatedness within each developmental stage of brood was lower in colonies of wet season than in colonies of dry season. In both dry and wet seasons, the gene frequencies were significantly different between groups of consecutive cohorts, suggesting that this species exhibits serial polygyny. P. satan builds satellite nests, but the building behaviors might not be associated with the resolution of conflicts among dominant reproductive females.
