Stockholm: A new research has found that bees buzz differently near mobile phone signals – causing behaviour that can endanger colonies.
Researchers placed two mobile phones in beehives and operated them alternately in standby mode and in connection with each other.
The results of the research, which was carried out at the Swiss Federal Institute of Technology, showed that when the phones were on standby, the bees`` buzzing did not change, but when the phone was activated, the bees`` buzz frequency rose significantly.
"This is clear evidence that the bees are sensitive to phone signals and are disturbed by mobile phones," the Local quoted research director Daniel Favre, as saying.
Favre explained that the bees normally only hum at a high frequency when they are about swarm out of a hive in search of food. He said that mobile phones could therefore cause the bees to leave the hive prematurely, before the queen has fully matured and there are no larvae to feed.
