CELLPHONES CITED AS POSSIBLE FACTOR IN LOSS OF BEES

While Cellphones may not cancer... this does sound plausible.
Telegraph, UK -  Britain has seen a 15 per cent decline in its bee population in the last two years Their disappearance has caused alarm throughout Europe and North America where campaigners have blamed agricultural pesticides, climate change and the advent of genetically modified crops for what is now known as 'colony collapse disorder.'

Now researchers from Chandigarh's Punjab University claim they have found the cause which could be the first step in reversing the decline: They have established that radiation from mobile telephones is a key factor in the phenomenon and say that it probably interfering with the bee's navigation senses.

They set up a controlled experiment in Punjab earlier this year comparing the behaviour and productivity of bees in two hives - one fitted with two mobile telephones which were powered on for two fifteen minute sessions per day for three months. The other had dummy models installed.

After three months the researchers recorded a dramatic decline in the size of the hive fitted with the mobile phones, a significant reduction in the number of eggs laid by the queen bee. The bees also stopped producing honey.

The queen bee in the "mobile" hive produced fewer than half of those created by her counterpart in the normal hive.

They also found a dramatic decline in the number of worker bees returning to the hive after collecting pollen. Because of this the amount of nectar produced in the hive also shrank.

Not sure?
Tim Lovett, of the British Beekeepers Association, said that hives have been successful in London where there was high mobile phone use.
"Previous work in this area has indicated this [mobile phone use] is not a real factor," he said. "If new data comes along we will look at it."
He said: "At the moment we think is more likely to be a combination of factors including disease, pesticides and habitat loss."
