Many researchers believe the reason is spore transfer on the pollen sources.
Those counting spores have always found a serious rise after bees are in a 
pollination.

Once in Florida I was standing in front of a small pool used for water in a
large holding yard. The beekeeper asked me if transfer of nosema ceranae
spores could come from a water source. I asked many researchers but none
knew the answer. Jerry or Randy?
