 The most interesting question
we are facing now is that in some hives varroa is under control after
treating hives with legal Apivar (Amitraz) strips but you see bees with
deformed wings! Is this a residual of virus symptoms after varroa gone?
How long does it take these symptoms to disappear if the vector (Varroa)
is not present or at a very low level?

Have seen this in hives in New Zealand with an Autumn treatment with Apivar.
