Re: How many dead-outs are the result of the 2 types of nosema?
Or, in the case of Nosena C., crawl off and die.

Second hand, so take it for what it's worth: Our club president and his mentor/partner sent live bees to a testing facility (in MT, I think). They had 400 of 1400 colonies dwindling or dead at pre-almond count three weeks ago (we're in WA state). Samples game back at 30 million spores per bee. Suggested treatment threshold is about 5 million per. Nosema was the predominate malady found, with varying levels of other virusus.
