Colony Collapse Disorder

Colony collapse disorder is a phenomenon in which worker bees from a beehive or European honey bee colony abruptly disappear. While such disappearances have occurred throughout the history of bee keeping, and were known by various names, such as disappearing disease, spring dwindle, May disease, autumn collapse, and fall dwindle disease, the syndrome was renamed colony collapse disorder in late 2006 in conjunction with a drastic rise in the number of disappearances of Western honeybee colonies in North America. European beekeepers observed similar phenomena in Belgium, France, the Netherlands, Greece, Italy, Portugal, and Spain, and initial reports have also come in from Switzerland and Germany, albeit to a lesser degree while the Northern Ireland Assembly received reports of a decline greater than 50%.
