Subject: AW: [BEE-L] Mite fall

Hi Andy,
the answer is - it depends.

If 50 mites over 24 hours is what you find without having treated
against
varroa (natural fall out) then this is a hell of a investation. You can
propably assume that the number of mites left in the colony is abot 100
-
200 (some scientists even suggest up to  300) times of that.

If however 50 mites is the result following a varroa treatment then it
is
low when you assume that your treatment was effective (and bees not
having
brood). However if you have doubts that your treatment was not effective
(because bees still having brood, the mists being resistant aginst the
drug,
etc...) then only 50 mites would be an indication of a unsuccessfull
treatment.

Albrecht
