Summary

The genetic variability of honey bees (Apis mellifera L.) from south eastern Europe was investigated using microsatellite analyses of 107 samples from Albania, the Republic of Macedonia, Greece and Bulgaria together with 42 reference samples (Apis mellifera carnica) from Slovenia. Genetic structure and spatial analyses of the microsatellite data showed a clear distinction between the Slovenian bees and all other populations, and confirmed the existence of Apis mellifera macedonica as an indigenous honey bee population in the regions that were sampled. In most areas however, varying degrees of introgression with A. m. carnica alleles could be observed, probably as a consequence of propagating imported queens. Within A. m. macedonica, a certain degree of subdivision between the honey bee populations from Bulgaria and the other regions was detected, confirming earlier reports of variation within this subspecies.

Resumen

La variabilidad genética de las abejas melliferas (Apis mellifera L.) de Europa sudoriental se investigó mediante el análisis de microsatélites de 107 muestras procedentes de Albania, la República de Macedonia, Grecia y Bulgaria, junto con 42 muestras de referencia (Apis mellifera carnica) de Eslovenia. La estructura genética y el análisis espacial de los datos de microsatélites mostraron una clara distinción entre las abejas eslovenas y las demás poblaciones, y confirmaron la existencia de Apis mellifera macedonica como una población de abejas de la miel indígena en las regiones que se muestrearon. En la mayoría de las áreas, sin embargo, se pudieron observar diferentes grados de introgresión de alelos de A. m. carnica, probablemente como consecuencia de la propagación de reinas importadas. Dentro de A. m. macedonica, se detectó un cierto grado de subdivisión entre las poblaciones de abejas melíferas de Bulgaria y de las otras regiones, lo que confirma informes anteriores de la variación dentro de esta subespecie.
