In this study, the genetic structure and diversity of honey bee populations from Thrace and Yigilca were investigated using 27 microsatellites. Except Kirklareli and Yigilca (Fst: 0.14), it was observed lower genetic divergence between the populations based on the value of pairwise Fst. Although Thrace populations (Edirne, Tekirdag and Kirklareli) were not fully separated from each other, Yigilca population was significantly separated from Kirklareli and separated slightly from the rest of other populations. The calculated gene diversity of the populations ranged from 0.44 in Kirklareli to 0.56 in Edirne and Tekirdag. Despite the high genetic diversity within the populations, the significant heterozygous deficiency found in Kirklareli may be due to repeated and controlled swarming of the selected colonies by beekeepers. These factors could have contributed the observed genotypic homogenization within Kirklareli honey bee population. Our results demonstrate that genetic differantiation of Thrace and Yigilca populations is still conserved, but gene flow is not prevented by the current management strategies, creating urgent demand for an improved conservation management of honey bee populations.en10.3906/vet-2103-12info:eu-repo/semantics/openAccessApis Mellifera L; Honey Bee; Genetic Diversity; Microsatellites; TurkeyApis-Mellifera L.; Turkish Honeybees; Turkey; Diversity; Software; Hymenoptera; Anatoliaca; Caucasica; Ecotypes; RegionsArticle45699910095191652-s2.0-85122622910WOS:000731915100004N/AQ4
