A few years back we had a good thread on high fructose corn syrup and the affect it has on the bee gut. I just brought home a box of winter patties from Mann Lake and checked the ingredients.
Sugar, high fruc corn syr, preservative, plant protein products.
I remember that high fruc corn syr was being considered for part of the reason for colony calapse disorder, in that it may upset the bees gut, and even lead to nosema.
What is the skinny nowa days on feeding bees high fruc corn syr?
