Bee colonies around the globe have declining at an alarming rate. Scientists suspect many factors may be responsible.
A study by Swiss researcher shows that mobile phone-generated electromagnetic fields may contribute to Colony Collapse Disorder (CCD), a condition that causes worker bees to desert the hive. In most cases, the queen bee is left with eggs, immature bees, and a lot of honey. The colony survives for a short time, but soon dies out without its workers.
Earlier studies have shown that cordless telephones placed at the bottom of beehives altered the behavior of honeybees that returned to the hive after foraging.
The researcher recorded sounds produced by bees in five healthy hives in two Switzerland locations between February and June 2009. The study recorded the bees' sounds with active mobile phones in the hive. Two mobile handsets (900MHz GSM) were chosen at random.
