Bijensterfte, oorzaken en gevolgen

California almond growers have reason to be worried, very worried. Honeybee populations across the country have declined sharply since last Fall. The California almond industry, supplying 80 percent of the world market of almonds, requires roughly half of the nation's commercial hives to pollinate its groves. This ratio might see a dramatic change when new tallies on hives are available this Spring. Many beekeepers have seen Winter hive losses as high as 50 percent. One Pennsylvania beekeeper told the Washington Post, “This was probably the worst year ever.”
