A study by 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.
"Recent efforts have been made to study another potential cause responsible for bee losses: manmade electromagnetic fields," Favre writes. And while the results obtained to date have been "highly controversial," they suggest a connection between the growing use of cellphones and a declining bee population.
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. However, other reports have between mobile phones and colony collapse.

Favre's 2009 study exposed honeybees to active cellphone radiation. "The goal of these experiments was to identify potential effects of mobile phone communications on honeybee behavior," he writes.
