But I'm not necessarily saying that your bees died from resistant mites. I'm
finding a 15% loss, with with another 10% weak. I think I'm seeing tracheal mite
damage coupled with dysentary. The windy yards didn't get the early cleansing
flights that the sheltered yards did. Lots of "boiled out" bees and evidence of
dysentary in these yards. All the yards must have tracheal mites, but only the
ones with dysentary problems are in poor shape. I've often wondered if the
tracheal mite stress causes dysentary, or dysentary makes the tracheal mite
problem worse.
