The mysterious disappearance of honeybees in America and other parts of the world could be explained by a virus which is transmitted by a parasitic mite, scientists believe. The virus has been identified in commercial bee hives which suffered from colony collapse disorder (CCD) ? when worker bees suddenly vanish without trace, leaving behind a queen bee and a store of pollen and honey. Although the link with the virus does not prove it causes CCD, experts think it plays a significant role, perhaps together with another, as yet unknown, agent. |
