And it turns out that the killer wasn’t the cell phone but an Asian parasite:

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.

Another theory points a finger at mobile phone aerials, but Higes notes bees use the angle of the sun to navigate and not electromagnetic frequencies.
