Bloomberg Business reported on Dennis and the Bee Informed Partnership annual honey bee survey
Beekeepers in the U.S. reported that 42 percent of the honeybees they managed last year died, the second-highest percentage since the survey began in 2010, as mites, viruses, and other maladies caused losses to spike. Pesticides exposure also may play a role in weakening bee population, said Dennis vanEngelsdorp, an assistant professor of entomology at the University of Maryland and project director of the Bee Informed Partnership.
Beekeepers lost 27.4 percent of their hives from April 2014 through September, up from 19.8 percent the previous year, according to the survey. Losses from October through March fell to 23.1 percent from 23.7 percent. “We’re a little frustrated that we’ve stabilized our winter losses only to see mortality go up in the summer,” vanEngelsdorp said.
