For what it's worth, EconTalk had a really fascinating interview with a honeybee economist (<-- thing that exists!).
Turns out:
* Practically 100% of US honeybees are domesticated; wild honeybees were wiped out in the late 80s by Varroa mites.
* Honeybees aren't native to the US; I'm not sure if I heard this right, but it may be that none of the social bees are.
* Colony collapse is largely a phenomenon observed during overwintering. Some 15% of domesticated colonies fail over the winter. CCD seems to have upped this figure to 30%.
* If CCD is causing problems for professional beekeepers, those problems don't seem to be reflected in the economy. The price of queen bees (raised by specialized apiarists to help other beekeepers split colonies) hasn't changed. The price of pollination services --- mostly for the California almond crop, which is fed by beekeepers from around the country --- hasn't changed significantly either, with the possible exception of a small spike in pollination fees at the peak of almond pollination season.
It's hard to reconcile what the economist reported with the alarmism surrounding colony collapse.
It's also difficult to compare the impact of "neonicotinoids" with that of the Varroa mite.
