摘要：汗蜂(Halictidae)在其社会组织中表现出很大的种间和种内多样性，但关于任何物种的社会发生组织的信息却非常少。软舌蜂是一种社会性汗蜂，其年度生活周期在其从北欧到南欧的广泛地理范围内的社会组织中表现出相当大的变化。我们在奥地利艾希科格尔靠近其分布纬度中心的31个麻雀巢中收集了所有成虫，并利用为该物种开发的5个高度可变的微卫星座位对148名工蚁进行了基因分型。在工蚁活动的第二阶段，当蜂群提供有性繁殖时，巢通常是无蜂王的(48%的巢)。谱系重建和对巢友遗传亲缘关系的估计表明，巢通常(32%的巢)含有外来工蚁，可能是由于工蚁从出生的鸟巢漂移到外国工蚁巢中的结果。蜂王有效交配频率是可变的(调和平均值Me=1.24)，但有时很高(最大值为2.7)。这些数据表明，木麻黄的巢没有典型的共生社会社会发生组织(一夫一妻制，一夫多妻制)，因此对分类单元中基于专有关联性的进化共生社会的论点提出了挑战。
Abstract.Sweat bees (Halictidae) exhibit great interspecific and intraspecific diversity in their social organisation, yet there is remarkably little information on the sociogenetic organisation of any species. Lasioglossum malachurum is a eusocial sweat bee with an annual lifecycle that exhibits considerable variation in its social organisation across its wide geographic range from northern to southern Europe. We collected all adults from 31 L. malachurum nests at Eichkogl, Austria, near the latitudinal centre of its distribution, and genotyped 148 workers using 5 highly variable microsatellite loci developed for this species. Nests were often queenless (48% of nests) during the second phase of worker activity, when colonies were provisioning the sexual brood. Pedigree reconstruction and estimates of nestmate genetic relatedness demonstrated that nests often (32% of nests) contained alien workers, probably as a result of worker drifting from their natal to a foreign nest. Queen effective mating frequency was variable (harmonic mean me = 1.24), but sometimes high (maximum 2.7). These data demonstrate that nests of L. malachurum do not have a classical eusocial sociogenetic organisation (monogyny, monandry) and thereby pose a challenge to exclusively relatedness based arguments for the evolution of eusociality in the taxon.
