Found a 2007 report on CCD at http://www.manataka.org/page1705.html The piece was written by Linda Moulton Howe. She has her own site, http://www.earthfiles.com/, if you like that kind of thing.
It quotes Dave Hackenberg, often credited as the first person to raise the alert on CCD. His commercial colonies suffer a very great deal from CCD, it seems, which may tell us something.
The Manataka site (http://www.manataka.org/) is full of piffle. I particularly like the homepage image, which (probably unconsciously) demonstrates how religions/cults/kabals/nutjobs and the rest borrow iconography from a single core theme (open hands, rays of light etc).
