Data From: Do diet and Fumagillin treatment impact Vairimorpha (Nosema) spp. (Microspora: Nosematidae) infections in honey bees (Hymenoptera: Apidae) and improve survival and growth of colonies overwintered in cold storage?

The data set contains two years of data on honey bee colony sizes expressed as frames (combs) of adult bees and brood, Varroa mites counted per 100 bees and Vairimorpha (Nosema) spp. spores in worker bees in each colony. The data set also contains measurement of fat body weights, protein and lipid concentrations made prior to and after colonies were overwintered in cold storage. In the year-2 data set, colony measurements, Nosema and Varroa mite counts and fat body metrics were separated by treatment group. The treatment groups were: colonies fed pollen or protein supplement and treated with Fumagillin for Nosema and colonies fed the same diets but not treated with Fumagillin for Nosema.
