Russian Honey Bee

The Russian honeybee refers to honey bees (Apis mellifera) that originate in the Primorsky Krai region of Russia. This strain of bee was imported into the United States in 1997 by the USDA's Honeybee Breeding, Genetics & Physiology Laboratory in Baton Rouge, Louisiana in response to severe declines in bee populations caused by infestations of parasitic mites,[1] and have been used in breeding programs to improve existing stocks.
