本文对不同社会性水平的社会性水虻的交配结构和巢亲关系进行了研究。微卫星标记已被开发用于公共蜜蜂（Andrena scottica）和原始真社会胡蜂（Vespula rufa）。在公共蜜蜂中，相同群体的雌性彼此不相关，这表明缺乏包容性的适应性回报可能有效地限制了它们的社会进化。有一个积极的近交系数为两个研究群体的Andrena scottica作为一个结果的高度内交配。这种近亲繁殖并没有导致广泛生产的二倍体男性将预期的基础上的CSD（互补性别决定）系统的蜜蜂，因此Andrena scottica要么避免“匹配交配”，（即任何一种或两种性别都不与携带相同性别等位基因的个体交配）真社会性寄生蜂Dolichovespula saxonica为一雄多蕊型，雌蜂（n=7）交配4-11次有效性乱ke为3.30-9.14（平均4.81）。这导致工人之间的平均相关性较低（gww=30-0.40;平均值0.37）。相反，Dolichovespula媒体皇后从三个殖民地交配一个男性只。所有雄性（n=80）来自四个D。萨克森殖民地由女王建立，符合女王和工人集体的遗传利益（“工人治安”）。一个D saxonica群体包括两个母系的工蜂和雄蜂。14个群体的蜂王交配次数为1-5次（平均2.43次），有效交配次数为1 ~ 2.8次（平均1.40次）。一半的殖民地检查，居住的外来工人。这些工人可能来自较早的巢篡夺事件，这些外来工人的殖民地平均规模较大。外来工人与一妻多夫制一起导致社会遗传组织中殖民地之间的高度变异。遗传学数据与所有雄性（n = 233）都是由殖民地女王产生的观点一致，与集体工人利益相冲突。
Mating structure and nestmate relatedness have been estimated in social Hymenoptera with different levels of sociality. Microsatellite markers have been developed for both communal bees (Andrena scottica) and for primetively eusocial wasps (Vespula rufa).In the communal bee, Andrena scottica, females of the same colony are not related to each other suggesting that the lack of inclusive fitness payoffs may effectively constrain their social evolution. There was a positive inbreeding coefficient for both examined populations of Andrena scottica as a result of a high degree of intranidal mating. This inbreeding did not lead to extensive production of diploid males as would be expected on the basis of the CSD (complementary sex determination) system of the honey bee, and thus Andrena scottica either avoids "matched matings", (i.e. either or both sexes refrain from mating with an individual carrying the same sex allele) or the sex determination departs from the honey bee model.The primitively eusocial wasp Dolichovespula saxonica is highly polyandrous.Queens (n=7) mated 4-11 times (mean 6.0) and the effective promiscuity, ke was 3.30-9.14 (mean 4.81). This resulted in low average relatedness among workers (gww=30-0.40; mean 0.37). On the contrary Dolichovespula media queens from three colonies mated with one male only. All males (n=80) originating from four D. saxonica colonies were produced by the queen, in agreement with the genetical interests of both the queen and the collective worker force ("worker policing"). One D. saxonica colony includedboth workers and male sexuals of two matrilines.Bombus hypnorum is a primitively eusocial bumble bee. Queens from 14 colonies had mated 1-5 times (mean 2.43) with an effective promiscuity of 1-2.8 (mean 1.40). Half of the colonies examined, inhabited alien workers. These workers could originate from an earlier nest usurpation event, and the colonies with such alien workers had on average a larger size. Alien workers together with polyandry results in high variation among colonies in sociogenetic organisation. Genetical data were consistent with the view that all males (n = 233 examined) were produced by a colony's queen, in conflictwith the collective worker interest.
