linkage between IAPV and CCD persists in the literature:

The interactions between pesticides, mite stresses and
diseases including the newly identified Israeli acute paralysis virus
[IAPV] are likely contributing factors, and support an
emerging hypothesis that no one factor alone is responsible for
the dramatic losses of honey bees in general or for CCD
specifically. Only the miticide coumaphos was at consistently
higher levels in non-CCD versus CCD colonies out of 50 pesticides
and metabolites found, supporting its beneficial role in
promoting apiary health by reducing Varroa mite stress.
