CCD is caused by pesticides. Specifically, neonicotinoids in a synergistic combination that is yet to be fully understood. That is the alarming conclusion that scientists are finally coming to, despite attempts by the pesticide manufacturers to distract, divert and even blackmail them into finding some other culprit. Clothianidin, Imidacloprid and other neocicotinoids must be withdrawn from use IMMEDIATELY or our bees are assuredly doomed.
