Effect of Feeding Honey Bee (Apis mellifera Hymenoptera: Apidae) Colonies With Honey, Sugar Solution, Inverted Sugar, and Wheat Starch Syrup on Nosematosis Prevalence and Intensity.

Here, we present the results of a 2-year field trial aimed at testing the effect of overwintering on different feeds on the course of Nosema ceranae infection. In August 2015, four experimental bee colony groups were established. After the last honey harvest, each colony was provided with 20 kg of feed, either honey, sugar (3:2 solution in tap water), inverted syrup made of sucrose, or wheat starch syrup.
