>Researchers still don't have a handle on CCD so what some say is conjecture without conclusive tests to back up the conjecture.> You'll have to ask the researchers why they are conjecturing. My only concern at this time is to support my conjecture that a single pathogen or single factor is not sufficient to cause a colony to collapse from CCD. And I will do this by quoting from a few 'conjectures' provided by leading researchers in the field. "Previous attempts to find the cause of CCD failed to identify a single factor that explained all cases of CCD (Cox-Foster et al. 2007, Johnson et al. 2009b, vanEngelsdorp et al. 2009)" "Pathogens might be causing the end result of a collapsed colony, but other factors are causing sickness in the bees," - Dennis vanEnglesdorp "This CART analysis provides evidence that CCD is likely the result of several factors acting in concert, making afflicted colonies more susceptible to disease."
