Ugh this is not the case at all.
It's possible that the pesticides in question aggravated bee declines, but in no way is it suspected to be the predominant culprit. Colony collapse has been ongoing since before the use of these pesticide applications, and is occuring in regions where the pesticide isn't used at all.
