纸黄蜂Polistes dominulus的女王可以选择在春天单独或与其他女王一起寻找巢穴。在后一种情况下，一个优势等级是建立在cofoundress与占主导地位的黄蜂得到的主要份额的繁殖输出的巢。一只黄蜂的不同繁殖策略将需要不同的行为。我们测量了大脑结构的体积，作为一个潜在的指标，不同的使用和阐述了一些大脑结构。我们发现一个显着增加的触角叶的体积在多个foundress协会的成员相比，单一foundress。衣领的体积，蘑菇体的花萼的子结构，也显着较大，特别是在一个foundress协会占主导地位的女王。在测量的大脑亚结构体积方面，没有发现优势黄蜂和从属黄蜂之间存在显着差异。版权所有（C）2001 S。Karger AG，巴塞尔。
Queens of the paper wasp Polistes dominulus have the option to found nests in spring alone or together with other queens. In the latter case a dominance hierarchy is established among the cofoundresses with the dominant wasp getting the major share of the reproductive output of the nest. The different reproductive strategies of an individual wasp will necessitate different behaviors. We measured the volumes of brain structures as a potential indicator of differential use and elaboration of a number of brain structures. We found a significant increase in the volume of the antennal lobe in members of multiple foundress associations in comparison to single foundresses. The volume of the collar, a substructure of the calyx of the mushroom body, was also significantly larger, especially in the dominant queen of a foundress association. No significant differences between dominant or subordinate wasps in regard to volume of the measured brain substructures were found. Copyright (C) 2001 S. Karger AG, Basel.
