and fail to return to their hives.
People have blamed genetically modified crops, cellular phone towers
and high-voltage transmission lines for the disappearances.
Or was it a secret plot by Osama bin Laden to bring down American
Investigators have heard it all.
Scientists first learned of the bee disappearances in November and
have been trying to find answers to explain 'colony collapse disorder',
the name given for the disappearing bee syndrome.
They are focusing on the most likely suspects: a virus, a fungus or
A recent survey of 13 states showed that 26 percent of beekeepers have
lost half of their bee colonies between September and March.
Researchers expressed concern about the speed at which adult bees are
disappearing from their hives; some colonies have collapsed in as

Others noted that countries in Europe, as well as Guatemala and parts
of Brazil, are also struggling for answers.
Honeybees are arguably the insects that are most important to the human

fruits, vegetables, flowers and nuts.
Large bee losses are not unheard of.
They have been reported at several points in the past century.
