I am only asking, not specualting, just asking a question: Could the changing of the structure of foods be a cause? I am thinking GMO’s and the like.
I missed the answer, but have it know
In light of the poison gluten and rice right now, I’m not going to pooh-pooh GMO’s being at least a culprit.
This is about pushing hives hard. Transporting them from state to state as the seasons change. Forcing the hives to grow to a population that completely overwhelms the hive. The bees then become sick with various diseases and die.
Any researcher worth his grant money will study all the angles you suggested, however, imho, there is no substitue for being a good stewart of a bee hive.
