CCD is an economic problem. The varroa mite wiped out feral North American honey bees --- which are not native to North America --- a long time ago. Supposedly, any honey bee you've seen in the wild for the past decade has been part of a proprietary hive.
So, ordering more honey bee queens off the Internet seems to be a pretty reasonable response to the problem of a 10-20% increase in overwintering hive failures.
