Mobile link to bee decline.

For years, beekeepers and conservationists have struggled to understand what could be causing the global decline in bee populations. Notwithstanding the usual suspects of intensive farming and loss of habitat, bee populations have fallen alarmingly in recent years.

Now, thanks to a Swiss researcher at the Ecole Polytechnique Federale (EPFL) in Lausanne, we may be close to unravelling the mystery. In a series of 83 experiments, Daniel Favre, a former-biologist with the institute, proved that mobile phone signals have a direct effect on bee behaviour. Using two hives, Favre conducted his experiments by placing a mobile phone next to each one and monitoring stress levels among the bees.


He found that each time a call was established on one of the phones, the humming of the stressed hive residents increased nine-fold--from 450 Hz to over 4,000 Hz--within just half an hour. In an interview with the French-language newspaper Le Matin, Favre explained that this showed that mobile telephony was a massive disturbance to bees, and could also be a reason for many insects abandoning their hives.
