Here is an article that speculates on a link between feeding bees high fructose corn syrup and Colony Collapse Disorder (CCD). Personally I have never lost a hive to what I would consider as CCD. CCD is characterized by departure of all bees but the queen and a few nurse bees and is not a winter phenomenon. My lost hives usually are related to going queenless in the summer or winter starvation. CCD mainly affects commercial beekeepers who frequently utilize high fructose corn syrup as a winter feed. This article indicates that the corn syrup may be the delivery mechanism for neonicotinoid pesticides to the bees. If that is true, it is also delivering that same pesticide to people via any food prepared using high fructose corn syrup.
