Colony Collapse Disorder, also known as Fall-Dwindle Disease, is of great concern to beekeepers worldwide. Beekeepers are reporting the sudden loss of adult bees in their colonies. There are few, if any, adult bees found in or near the affected colonies. Queen and baby (brood) bees remain in the colonies, but the adults are not returning to provide food, so the colonies collapse and/or die. Over 22 North American states reported significant colony losses in the fall of 2006. Similar reports are coming from Europe as well. Researchers are considering viruses, bacteria, fungi, weather, food loss, and other stresses as possible causes. Additional information can be found through the links below.
