Research Project: IMPROVE NUTRITION FOR HONEY BEE COLONIES TO STIMULATE POPULATION GROWTH, INCREASE QUEEN QUALITY, AND REDUCE THE IMPACT OF VARROA MITES

Location: Honey Bee Research

Project Number: 5342-21000-015-00
Project Type: Appropriated

Start Date: Oct 01, 2008
End Date: Sep 30, 2013

Objective:
1: Determine the nutrients in pollen that promote worker longevity. 1.A. Determine the effects of pollen mixtures on worker protein and lipid stores and longevity. 1.B. Characterize the chemical composition of pollen mixtures that optimize worker protein and lipid stores and longevity. 2: Determine the effects of undigested saccharides in high fructose corn syrup (HFCS) on worker physiology and longevity. 2.A. Identify the saccharides in HFCS. 2.B: Determine the effect of saccharides in HFCS on worker physiology and longevity. 3: Evaluate the effects of supplemental feeding on Varroa tolerance, queen production and foraging activity of honey bee colonies. 3.A. Modify the MegaBee diet by adding chemical components that were identified in the pollen mixture analysis. 3.B. Determine the effects of nutrition on Varroa infestation and reproduction in worker and drone cells. 3.C. Determine the role of nutrition on queen production and reproductive potential. 3.D. Evaluate the effects of supplemental protein feeding on the foraging rates of honey bee colonies. 3.E. Improving honey bee immune response to CCD by determining the role of symbiotic microbes in bee nutrition. 3.F. Develop IPM tools (e.g., "soft" miticides that are non-toxic to workers and queens, traps, and exclusion devices) and methodologies for control of key pests (especially Varroa mites), and miticide resistance management programs to preserve useful chemical options. 3.G. Determine the impact of the small hive beetle on colony development and longevity, and develop management systems for controlling the beetle in hives, including use of antifeedants for protection of protein supplements from small hive beetle damage. Develop effective control programs for management of small hive beetle in bee hives, with the goal to prevent contamination of bee products.

Approach:
1. Nutritional value will be evaluated by measuring protein and lipid levels and on bee longevity. The chemical composition of pollens that are more nutritious than MegaBee will be determined. 2. Determine the effects of high fructose corn syrup containing higher saccharides on honey bee longevity. 3. Determine the effects of improved nutrition of the longevity of bees parasitized by Varroa, the reproductive potential of queens, and foraging activity of colonies used for pollination. REPLACING 5342-21000-014-00D (8/08). FY09 Program Increase $270,000. FY10 Program Increase $315,000.
