Colony Collapse Disorder

CCD

Colony collapse disorder (CCD) refers to the rapid loss of adult worker bees from hives, resulting in weak or dead colonies with excess brood present relative to adult bees, a noticeable lack of dead worker bees both within and surrounding the hive, the delayed invasion of hive pests (Small hive beetles and wax moths) and kleptoparasitism from neighboring honey bee colonies, the absence of Varroa mites (Varroa destructor) and nosema loads at levels thought to cause economic damage.
