Condition and Honey Productivity of Honeybee Colonies Depending on Type of Supplemental Feed for Overwintering.

Harvested honey is usually replaced by an alternative sugar to overwinter honeybee colonies. Supplementation of winter stores with beet or cane sucrose is safe for colonies and does not cause winter mortality. Despite this, there are hypotheses that supplementation of inverted sugars has the potential to give better results in overwintering, spring growth, and honey production of the colonies, because bees are consuming already cleaved feed. Therefore, we compared the condition parameters and honey production in 70 colonies at four apiaries overwintered with stores from sucrose or inverted sugars. No statistically significant differences in dependence on the type of the supplemental feed were found. Inverted sugar was more expensive than sucrose for feeding colonies. Economic efficiency, physiological consequences, and other disadvantages of using invert syrups are discussed.
