Interpretive Summary: Honey bee colony feeding trials were conducted to determine whether differential effects of carbohydrate feeding (sucrose syrup vs. high fructose corn syrups) could be detected between colonies fed exclusively on these syrups. In one experiment, colonies installed within a closed arena had increased wax production (F 1,6 = 6.850, p = 0.040). On average, the colonies supplied with HFCS built 566.88 in sq. of honeycomb (plus or minus 97.666 in sq.), while the colonies supplied with sucrose built 981.73 in sq. (plus or minus 125.312 in sq.). Mean mass of colonies supplied with HFCS was 4.65 kg (plus or minus 0.95 kg) while those supplied with sucrose had a mean of 8.27 kg (plus or minus 1.224). Differences in brood production were complicated due to a possible nutritional or microbial deficiencies experienced by both treatment groups. In the second experiment, colonies supplemented with sucrose syrup through the winter months at a remote field site, exhibited increased spring brood production when compared to colonies fed with HFCS (F 1,8 = 5.693, p = 0.044). However, the adult bee population trended towards significant (F 1,8 = 5.011, p = 0.056) with an overall average of 9.95 frames of bees fed the sucrose syrup between November 2008, and April 2009 compared to 7.5 frames of bees fed exclusively on HFCS. Though sucrose syrup shows a high longevity advantage over HFCS in laboratory bioassays, the increase in field productivity was not as pronounced.
