由于亲缘关系在进化和行为研究中的重要性，社会生物学家长期以来一直试图精确估计群居昆虫群体成员之间的亲缘关系。利用微卫星技术，我们直接鉴定了意大利蜜蜂（Apis mellifera mellifera）、意大利蜜蜂（A. M. carnica和A. M. ligustica）。通过进一步的调查集中在一个A，M。在意大利蜜蜂群体中，我们发现，只要殖民地由同一个蜂王领导，遗传结构就基本上保持不变。殖民地内的遗传多样性也为当地蜜蜂种群的遗传多样性提供了一个很好的估计。与原殖民地同期的pueries相比，在群集工人的父系的分布是显着不同的，可能是由于不平等的倾向，群集之间的父系。相反，没有偏见之间的相对比例工人和女王育雏可以检测到。
Sociobiologists have long sought to estimate precisely the relatedness among members of social insect colonies because of the central significance of kinship in evolutionary and behavioural studies. By using microsatellites, we directly identified the 7-20 subfamilies (patrilines) present in five honeybee colonies belonging to three different subspecies (Apis mellifera mellifera, A. m. carnica and A. m. ligustica). By focusing further investigations on one A, m. mellifera colony, we showed that the genetic structure remained largely unchanged over time as long as the colony is headed by the same queen. The genetic diversity within the colony also provided a good estimate of the genetic diversity of the local honeybee population. The distribution of patrilines was significantly different in swarming workers compared with contemporaneous pupae of the original colony, probably due to unequal propensities for swarming among patrilines. Conversely, no bias in the relative proportions between worker and queen brood could be detected.
