Colony Collapse Disorder

Colony Collapse Disorder

 

Additional Resources

Colony Collapse Disorder (CCD) is the name given to the mysterious decline of honey bee populations beginning in 2006. On average, the U.S. Department of Agriculture (USDA) reports that beekeepers have been losing over 30% of their honey bee colonies each year.  CCD appears to have multiple interacting causes, including Varroa mites, pathogens and sublethal pesticide exposures.  Key symptoms of CCD include: 1) inexplicable disappearance of the hive's worker bees; 2) presence of the queen bee and absence of invaders; 3) presence of food stores and a capped brood.
