Social wasps show an obvious evolution of the differentiation in behavior and external size between reproductive and non-reproductive females, with no clear differences in the Stenogastrinae, via overlap in the Polistinae, to clear differences in the Vespinae. In this study, we examined the morphological appearance of the spermatheca in representative species of these three subfamilies. The general anatomical organization of the spermatheca comprises a reservoir, a duct and two spermathecal glands, and is in line with its common structure in other social Hymenoptera. All examined wasp species have a spermathecal reservoir with uniform wall thickness, which is similar to the situation in the bees, but differentiates them from the ants. Within the wasps, the shape of the reservoir, the shape of the spermathecal glands and their attachment site to the spermatheca differs among the Stenogastrinae, Polistinae and Vespinae. The reservoir wall is thick in the Polistinae and Vespinae, while in the Stenogastrinae, it varies from thin in Parischnogaster to thick in Eustenogaster, with an intermediate situation in Liostenogaster. In all examined species, we found no differences in the spermathecal development between reproductive and non-reproductive wasps.
社会性黄蜂在生殖型和非生殖型雌蜂之间表现出行为和体型差异的明显进化，从狭腹胡蜂亚科没有明显差异，经马蜂亚科存在重叠，到胡蜂亚科有明显差异。在本研究中，我们检查了这三个亚科代表性物种的受精囊形态。受精囊的一般解剖结构包括一个储精囊、一条导管和两个受精囊腺，这与其在其他社会性膜翅目昆虫中的常见结构一致。所有被检查的黄蜂物种都有一个壁厚均匀的储精囊，这与蜜蜂的情况相似，但与蚂蚁不同。在黄蜂中，狭腹胡蜂亚科、马蜂亚科和胡蜂亚科的储精囊形状、受精囊腺形状及其与受精囊的附着部位有所不同。马蜂亚科和胡蜂亚科的储精囊壁较厚，而在狭腹胡蜂亚科中，从巴黎狭腹胡蜂的薄壁到真狭腹胡蜂的厚壁不等，李氏狭腹胡蜂处于中间情况。在所有被检查的物种中，我们发现生殖型和非生殖型黄蜂的受精囊发育没有差异。
