Why Winter Bees are Key to Colony Health and Survival
Dr. Gard W. Otis, University of Guelph, Canada, and Institute of Bee Health, Switzerland
Honey bees in winter are physiologically very different from summer bees. Winter bees store fat, have inactive brood food glands, become inactive, and live much longer than summer bees while their colony is not rearing larvae. The health of winter bees strongly influences colony survival during winter, so they are not only of academic interest to us humans. What exactly are winter bees? When are they produced? What causes them to become winter bees and not short-lived summer bees? And how does our bee management affect the health of winter bees?
