One thing that seems interesting to me is Paul Stamets' work around mushroom nectar. Now I have no bloody idea whether or not anything he's come up with has been independently validated (and I really should) but his claims (at least at the time) were that the nectar derived from a number of different mushrooms reduced viral load in bees by a staggering amount across a number of significant viruses. Including the deformed wing virus - which is exactly what it sounds like. The virus not only limits how efficiently and thus how far a bee can fly, it limits how long they can do it for. They live short and die young. This majorly constrains the hives in two very significant ways: A reduced grazing radius: a bee that can only go half as far only has access to one quarter the food supply. A bee that dies young needs to be replaced early, so the hive gets hungrier. Increased needs and reduced resources kills the hive.
