The last time I checked
CCD was being attributed to multiple contributing factors
(over work: being shipped from state to state to pollenate
on demand, parasites, pesticides, viruses + the medication
used to treat each individual pathogen)
…all of which contribute to the general weakening of each
individual + collective ability for the colony to sustain itself.
Short answer: NONE of the above, Yet ALL of the above.
CCD is not attributed to one isolated factor.
The Neonics seem to be the proverbial back-breaking straw.
