The annual nationwide survey by the Bee Informed Partnership found 37.7% of honeybee colonies died this past winter, nearly 9 percentage points higher than the average winter loss. The survey of nearly 4,700 beekeepers managing more than 300,000 colonies goes back 13 years and is conducted by bee experts
WASHINGTON — Winter hit U.S. honeybees hard with the highest loss rate yet, an annual survey of beekeepers showed.
Beekeepers had been seeing fewer winter colony losses in recent years until now, said Maryland's Dennis vanEngelsdorp, president of the bee partnership and co-author of Wednesday's survey.Some bees usually die over winter, but until the past couple decades, when a combination of problems struck colonies, losses rarely exceeded 10%, he said.
Year-to-year bee colony losses, which include calculations for summer, were 40.7%, higher than normal, but not a record high, the survey found.
