Colony Collapse Disorder Update

Colony collapse disorder (CCD) is a phenomenon in which worker bees from a honey bee colony abruptly disappear. While these disappearances have been observed throughout the history of beekeeping, the term CCD was first applied to a dramatic disappearance of honey bee colonies in the United States during the winter of 2006 / 2007, where nationwide 32% of colonies simply vanished.

Despite many claims and theories, there is still no certainty as to what is causing bees to disappear. It has been suggested that CCD may be due to a combination of stresses on the honey bees, with no single factor the ultimate cause. The USDA has reported high levels of pathogens, pesticides, and parasites present in CCD colonies, and lower levels in non-CCD colonies. Other stresses include loss of flowering habitat and large areas of mono-cultures, such as corn, soybean, and other commercial crops.
