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.' Britain has seen a 15 per cent decline in its bee population in the last two years and shrinking numbers has led to a rise in thefts of hives.
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 phone, a significant reduction in the number of eggs laid by the queen bee. The bees also stopped producing honey.
