Do bees need proteins and carbohydrates?
Honey bees (Apis mellifera) rely on a complex diet to maintain colony health, productivity, and resilience. Among the most vital components of their nutrition are proteins and carbohydrates. These macronutrients not only fuel daily activity but also influence brood development, immunity, longevity, and foraging efficiency. Understanding their roles and dietary sources is essential for both traditional and modern beekeeping, especially as environmental changes and habitat loss continue to affect floral diversity. The Role of Proteins in Honey Bee Physiology Proteins are critical for the growth and development of honey bee larvae, as well as for the maintenance and repair of tissues in adult bees. They are especially important in the production of royal jelly, brood food, enzymes, and immune proteins. Nurse bees require high protein intake for gland development, particularly the hypopharyngeal glands, which secrete larval food (Crailsheim et al., 1992). Protein deficiency can lea...
