MADRID, July 18 (Reuters) - A parasite common in Asian bees
has spread to Europe and the Americas and is behind the mass
disappearance of honeybees in many countries, says a Spanish
scientist who has been studying the phenomenon for years.
The culprit is a microscopic parasite called nosema ceranae
said Mariano Higes, who leads a team of researchers at a
government-funded apiculture centre in Guadalajara, the
province east of Madrid that is the heartland of Spain's honey
industry.
He and his colleagues have analysed thousands of samples from
stricken hives in many countries.

less vulnerable to it, but it can kill European bees in a matter of
days in laboratory conditions.
