WASHINGTON – Today the U.S. Department of Agriculture released its annual report on honey bee losses in the United States based on a national survey of beekeepers conducted with the Bee Informed Partnership. During the winter of 2013-2014, U.S. beekeepers lost 23.2 percent of their hives on average, which is lower than average losses in recent years, but considered too high to be sustainable. Preliminary results indicate that the number of summer bee losses (April-October) significantly increased from 12.5 percent in 2012 to 20 percent in 2013.

Scientists have attributed alarming bee declines in recent years to several key factors, including exposure to the world’s most widely used class of pesticides, neonicotinoids. A recent study by Harvard School of Public Health identifies neonicotinoid pesticides as “likely the main culprit” in Colony Collapse Disorder and adds to the strong body of evidence implicating these pesticides as a key contributing factor to bee declines.

“These dire honey bee numbers add to a consistent pattern of unsustainable bee losses in recent years. When combined with steep declines in wild pollinators, they point to the urgent need for action,” said Lisa Archer, director of Friends of the Earth’s Food and technology program. “Bees are the canary in the coal mine for our food system. While various factors are contributing to bee deaths, a strong and growing body of science tells us we must take action now to protect bees from neonicotinoid pesticides.”

In 2013, European Union banned the three most widely used neonicotinoids based on the weight of scientific evidence indicating that these pesticides can kill bees outright and make them more vulnerable to pests, pathogens and other stressors. However, these pesticides are still widely used in the U.S., despite massive bee losses that threaten vital food crops, from almonds in California to apples in Washington.
