In North County Dublin, Ireland, a region that has a relatively self-contained beekeeping regime with little movement of colonies or queens into the area, tolerance (co-adaptation) to varroa mites is becoming established.

Conservation efforts for A. m. mellifera are underway in multiple European
countries requiring reliable and cost-efficient molecular tools to identify purebred colonies. Here, we developed four ancestry-informative SNP assays for high sample throughput genotyping using the iPLEX Mass Array system.
