Genome sequencing shows climate barrier to spread of Africanized bees

A wild honeybee in Davis, California. European honeybees (Apis mellifera) were introduced to the Americas in the 1600s. Since 1957, “Africanized” honeybees (Apis mellifera scutellata) have interbred with other honeybees. New genomics research shows that climate forms a barrier to the spread of these scutellata genes to the north and south. Credit: Erin Calfee Since […]
