More than a third of the nation’s managed honeybee colonies were lost this past winter. The USDA Ag Research Service and Apiary Inspectors of America survey found starvation, poor weather and weak colonies going into the winter as the top reasons for the losses. The 33.8 percent loss compares to a 29 percent loss in the winter of 2008-2009 and 35.8 percent in the winter of 2007-2008.
Around 28 percent of the beekeepers reported their colonies perished without any dead bees present, a possible sign of Colony Collapse Disorder. This group also suffered substantially heavier losses than those without signs of CCD. There is still no known cause for CCD.
The interview-based survey checked about 22 percent of the nation’s estimated 2.46 million colonies and reports only winter losses. There have been significant colony losses in summer as well.
