The problem with suggesting that neonics are the underlying cause of CCD, having sublethal effects and combining with other stresses/phenomena to create CCD symptoms has been disproved by every kind of survey data to date.  The data shows no relationship between the types of crops, kind of beekeeper, region or other environmental correlation to CCD.  CCD is not due to an environmental condition in combination with exposure to neonicotinoids.
CCD is clearly caused by a disease organism.  As such, any stresses whatsoever can act in concert with a disease to give it the upper hand over the bees immune system, assuming they would have any helpful immune response at all to this particular disease organism.  Environmental factors, including beekeeping practices, miticides, pesticides, etc. are equally but not-surprisingly an agravating factor in any disease epidemic.  Thus, assaulting any particular environmental factor (global warming, neonicatinoids, migratory practices, nutrition, flooding, draught, cold winters, hot summers, full moon, blue moon, etc.) without addressing the infectious disease is pointless.
