“Why a mobile phone ring may make bees buzz off: Insects infuriated by handset signals”
Signals from mobile phones could be partly to blame for the mysterious deaths of honeybees, new research shows.

In the first experiment of its kind, a bee expert placed a mobile phone underneath a hive and then carefully monitored the reaction of the workers.

The bees were able to tell when the handsets were making and receiving calls, and responded by making the high pitched squeaks that usually signal the start of swarming.

Dr Daniel Favre, who carried out the experiment, believes signals from mobile phones and masts could be contributing to the decline of honeybees and called for more research.

Original prediction from Cosmic Awareness issue 2009-03 page 8:

Other problems that are very pressing and also contribute to the disappearance of the bees are such things as the microwave towers that are being used to beam microwaves around the country and around the planet. These microwave energies are very disrupting to the bees also, and as this Awareness has spoken on this matter on previous occasions, there is a need to adjust this technology to find a different way of allowing cell phones to be used, other than the microwave technologies that are currently being used, this too is seen as a contributing factor in the death and destruction of bee populations.
