Honey bees are an introduced species.
The last feral North American honey bees were wiped out in the 1980s, by the Varroa mite.
There are thousands of North American bee species that aren't honey bees. Some of them may be threatened by any number of factors (most likely: habitat encroachment).
But an important thing to remember about wild bees and the honey bee CCD phenomenon is that many wild bee species, including important pollinators, aren't social. Mason bees, for instance, don't have colonies: every female makes her own nest. CCD is a social bee phenomenon.
I think? it's possible that there are no North American native social bees that overwinter entire colonies the way honey bees do. For instance, all the bombus bees have colonies that last only a year (the colony produces new queens, which start entire new colonies). If that's the case, CCD is a phenomenon that definitionally only affects foreign introduced livestock bees.
