Thank you for this piece of information, Allen--that is a good number to
know!

These were either 48 or mostly 72 hour drops. I checked the fishiness vs a
powdered sugar "accelerated" drop immediately after taking the stickyboard
counts. There was a robust correlation with alcohol wash, so I dropped my
incredulity. And since that point have put little faith in one-shot
natural mite drops.
In any case, I am not arguing with you in any way that when a colony reaches
a natural drop of 50, or washes indicating mite levels above 10%, at a time
that it is curtailing broodrearing (such as in October) that that colony is
clearly in the danger zone of being taken down by a virus epidemic (or more
properly, "epizootic").
