2Sox; Google invertase in honey bees, look at the videos on youtube on feeding honey bees (the ones produced by known bee researchers, not those by first year beekeepers), read the ABC & XYZ of beekeeping and the Hive and the Honey Bee, and see if you can find USDA publications on the feeding of honey bees, or the publications by Doug Somerville, or Haydak, or Moeller, or Johansson. Find Leslie Bailey or Brenda Ball and read their study on what food is best for wintering honey bees.
Be sure to keep your eyes open for anything that says sugar syrup must be inverted for feeding bees, or that the ph must be changed.
