Hello All,
Zachary Huang has experience with nosema ceranae if he will comment. I do
understand the nosema ceranae responds to fumidil.
I am about 99% sure that was what I was told when I asked about the new
nosema ceranae named by Fries in "96."

Bailey in 1957 decribed an effective method for fumigating  nosema spore
equipment which used acetic acid (80 %)

Shiminuki (1973)reported complete inactivication of nosema spores when they
used ethylene oxide for 24 hours at 37.8 celsius *if* the relative humidity
was held at 80% .

Dr. Shiminuki did quite a bit of research on nosema. In 1970 he was the
first to show you could decontaminate nosema spores with high temps alone. I
believe around 50 celsius for 24 hours from memory.

Freezing has zero effect on nosema spores.

A search of the net should provide the papers on the subject by Shiminuki
and Bailey. I also believe the papers were published in either ABJ or BC.

If you can not find the published papers I will try.

Goes without saying the above is done on equipment free of bees.

With respect,

Bob
