Also, bear in mind that the NZ study Adony mentioned compared races of individual bees in cages and found no difference in the effect of dosing with Nosema.  Let colonies fly and things will be different.  Amm is likely to fly in poorer conditions than other races and so deposit the spore load away from the colony.

all the best
