Conservation of European M-lineage honey bees using abdominal colour as an indicator of subspecies purity has pitfalls

, 2022
There are 31 honey bee (Apis mellifera) recognized subspecies, which have been grouped into four main lineages. Two of these lineages occur naturally in Europe: M in western and northern Europe and C in southeastern Europe. In Europe, M-lineage groups only two subspecies, Apis mellifera mellifera and Apis mellifera iberiensis, both being black in ...
