Peter asks:
Does anyone know if V.d. can, or has, transferred to cerana?

All the known varroa can exit on cerana. I believe in areas of Asia VD now
infests cerana.

Peter asks;
  If so, can
cerana cope with it in the same way that it copes with V.j.?

I my knowledge yes.

Despite what others will tell you about grooming being the main reason
varroa is able to coexist with cerana the real *main* reason is that  for
some unknown ( yet undiscovered) reason varroa is not able to reproduce in
cerana worker brood so a measure of natural control is had.

Sincerely,
Bob Harrison
