WASHINGTON - America's honeybee hives just staggered through the second highest death rate on record, with beekeepers losing nearly half of their managed colonies, an annual bee survey found. Beekeepers told the surveying scientists that 21% loss over the winter is acceptable and more than three-fifths of beekeepers surveyed said their losses were higher than that. The overall bee colony population is relatively steady because commercial beekeepers split and restock their hives, finding or buying new queens, or even starter packs for colonies, said University of Maryland bee researcher Nathalie Steinhauer, the survey's lead author. Some commercial beekeepers who have succeeded in the past lost as much as 80% of their colonies this past year, while other beekeepers did well, it varied so much, Evans said. The demand for pollination from commercial bee colonies is growing even as the beekeepers have to work harder to make up for losses, Steinhauer said.
