From time to time a hive simply gives up the ghost and vanishes. Colony collapse disorder, as this phenomenon is known, has been getting worse since 2006. Some beekeepers worry that it may make their trade impossible, and could even have an effect on agriculture--since many crops rely on bees to pollinate them. Climate change, habitat destruction, pesticides and disease have all been suggested as possible causes. Nothing, though, has been proved. But the latest idea, reported in Naturwissenschaften by Jeff Pettis of the Bee Research Laboratory in Beltsville, Maryland, suggests that this may be because more than one factor is involved.
