This maybe old news for some. I ran across it researching winter feeding. The Journal of Insect Science Published online March 16 2013 http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3735052/ Comparison of Productivity of Colonies of Honey Bees, Apis mellifera, Supplemented with Sucrose or High Fructose Corn Syrup Diana Sammataro 1 , a , * and Milagra Weiss 2 , b Abstract snip: "Honey bee colony feeding trials were conducted to determine whether differential effects of carbohydrate feeding (sucrose syrup (SS) vs. high fructose corn syrup, or HFCS) could be measured between colonies fed exclusively on these syrups." Condensed version: sucrose sugar fed bees produced 30% more comb and brood than bees fed HFCS snip: "Because the sugar profile of HFCS is very similar to that of honey" snip: "Though honey has long been considered to be the â€œideal bee feedâ€ (Bailey 1966), researchers and beekeepers have recognized that sucrose may be a better sugar supplement (Herbert 1992)." snip: "SS has long been recognized by beekeepers as having a stimulatory effect, such as an increase in egg-laying and pollen-gathering activities (Barker 1971), as well as increased hygienic behavior (M. Spivak, Department of Entomology, University of Minnesota, personal communication). Free and Spencer-Booth (1961) observed bees switching their foraging strategy after sucrose feeding; they noted a decrease in the number of nectar foraging bees and an increase in pollen foraging bees to support colony brood rearing." Heresy ?
