孤雌生殖是指由未受精的卵产生二倍体雌性，最近在一些种类的蚂蚁中有报道。在这里，我们记录thelytokous繁殖女王在一夫多妻制物种Pyramica membranifera。在实验室中出现的蚁后在实验室条件下与或不与工人一起饲养。独立的殖民地成立是成功的几个皇后，如果猎物提供。所有的人工殖民地，都是从一个新出现的蚁后和工蚁开始生产新的工蚁，有些殖民地还生产雌性。一些雌性有性生殖者在实验室中脱落了翅膀，开始形成新的一夫多妻殖民地。工蜂没有卵巢，因此是强制性不育的。
Thelytokous parthenogenesis in which diploid females are produced from unfertilized eggs, was recently reported for some ant species. Here, we document thelytokous reproduction by queens in the polygynous species Pyramica membranifera. Queens that emerged in the laboratory were kept with or without workers under laboratory conditions. Independent colony founding was successful for a few queens if prey was provided. All artificial colonies, which started with a newly emerged queen and workers produced new workers and some of the colonies also produced female sexuals. Some of the female sexuals shed their wings in the laboratory and started formation of new polygynous colonies. Workers had no ovaries and thus, were obligatorily sterile.
