A study by Mohamed Alburaki, Dennis vanEngelsdorp, and colleagues suggests that overall, US honey bee populations exhibit low genetic diversity. Working with a large sample of honey bee specimens collected from most US states, the researchers determined that there are just three maternal evolutionary lineages in the populations: the North Mediterranean lineage, the West Mediterranean lineage, and the African lineage. They found that of the specimens from Montana, 100% descended from the North Mediterranean lineage—a finding in keeping with that for the lineage in many of the other states studied.
