Abstract

Beekeeping as a staple of agriculture in Kazakhstan is believed to have emerged when external bee colonies were introduced into the country. To date, six subspecies have been distributed across commercial apiaries (Apis mellifera sossimai, A. m. carpatica, A. m. mellifera, A. m. ligustica, A. m. caucasica, and A. m. carnica). In this study, we analyzed mitochondrial DNA from 21 geographically distinct populations with diverse subspecies composition and discovered 19 unique haplotypes belonging to C and M evolutionary lineages. Analysis of 9 microsatellite loci revealed strong polymorphism, with a range of 5 to 35 alleles at each locus. The observed heterozygosity across the populations varied from 0.2892 to 0.9099, and clustering analysis only allowed differentiation of each population based on its geographical location. High degree of admixture among subspecies was identified in every population, including a potential introgression from the endemic bee A. m. pomonella. Unregulated cross-breeding for the past 50 years has laid the foundation for the promiscuous genetic nature of honeybee populations in Kazakhstan.

哈萨克斯坦蜜蜂种群遗传多样性的首次评估

据信，养蜂作为哈萨克斯坦农业的主要内容是在外来蜂群引入该国时出现的。迄今为止，已有6个亚种分布在商业养蜂场中(蜜蜂、卡帕蒂卡蜜蜂、蜜蜂、ligustica蜜蜂、高加索蜜蜂和尼卡蜜蜂)。在这项研究中，我们分析了21个地理上不同、亚种组成不同的种群的线粒体DNA，发现了19个独特的单倍型，属于C和M进化谱系。9个微卫星位点多态性较强，每个位点有5 ~ 35个等位基因。群体间的杂合度变化范围为0.2892 ~ 0.9099，聚类分析只能根据地理位置对群体进行区分。在每个种群中都发现了亚种之间的高度混合，包括来自地方性蜜蜂a. m. pomonella的潜在渗入。过去50年来不受管制的杂交育种为哈萨克斯坦蜜蜂种群的混杂遗传性质奠定了基础。

期刊介绍： Apidologie is a peer-reviewed journal devoted to the biology of insects belonging to the superfamily Apoidea. Its range of coverage includes behavior, ecology, pollination, genetics, physiology, systematics, toxicology and pathology. Also accepted are papers on the rearing, exploitation and practical use of Apoidea and their products, as far as they make a clear contribution to the understanding of bee biology. Apidologie is an official publication of the Institut National de la Recherche Agronomique (INRA) and Deutscher Imkerbund E.V. (D.I.B.)
