I agree wholeheartedly Jeff! I've searched for some data on this, but have not been able to find much. Of course a post-mortem analysis is made much more difficult by the fact that researchers still don't really know what they are looking for. I understand that all CCD tested hives to date have tested positive for IAPV, though it is only considered a CCD marker--not the cause of CCD. As more and more data comes in and is made available to the public (published) it is becoming clear that a big part of the problem is the long-term, cumulative, sub-lethal impacts upon the bees from the plethora of pesticides and fungicides that they are exposed to when foraging. I think we will find that somewhere in the synergistic relationships between these various pesticides, coupled with stress from transportation and varroa, lies the cause of CCD.
