James,
Thank you very much for the reference. I guess in a well insulated/wrapped
hive the spores in the Nosema in the honey (if present) would remain
viable. The internal Ts rarely drop below -5C (locations away from main
cluster) even at -40C. Another thing to test and compare :)
I'll contact the national bee diagnostic lab to see if they can run PCR
Nosema tests for honey.

This reference mentions the spores being viable for at least 5 years. Even
those that were stored at -20C.
