            Deformed wings  are produced by a virus. I have a report and it
says "  Deformed wings virus is a particle that we have recently isolated
and characterised. It is usually associated with the infestation of
colonies by  varroa, and causes the deformed wings often seen on mite
infested bees. "
The report is from ROTHAMSTED- Experimental Station. UK.(1995)
For a long time  we have been thinking that deformed wings
were the result of a heavy infestation  in the capped brood  but the real
reason is the virus. Of course varroa acts as a vector the same as in APV
and others.
