Veterinary Clinics of North America: Food Animal Practice, 2021
At the individual level, honey bees (Apis mellifera) rely on innate immunity, which operates through cellular and humoral mechanisms, to defend themselves against infectious agents and parasites. At the colony level, honey bees have developed collective defense mechanisms against pathogens and pests, such as hygienic and grooming behaviors.

Alcohol dehydrogenase polymorphism in Apis mellifera

Biochemical Genetics, 1977
A polymorphic system of ADH isozymes is described in the honeybee Apis mellifera. Three and six different electrophoretic patterns were found, respectively, in drone and worker pupae analysis. The data indicate that the ADH isozymes are controlled by three alleles, Adh-1(1), Adh-1(2), and Adh-1(3). The frequency of the Adh-1 alleles is different in two
