no longer just about the pesticides or pollution or climate change. Also the mass use of mobile phones may be one of the culprits of the tragic death of hundreds of millions of bees worldwide. Daniel Favre, a researcher at the Federal Institute of Technology, Switzerland, has just published a study showing chelae signals emitted by mobile phones during a conversation are able to disorient the bees to the point of putting them into death. Fabre has made up to 83 different experiments to test and measure the reaction of the bees in the presence of a mobile operation.
The results seem to leave no doubt. Favre's team found that in the presence of a cell phone makes or receives a call, the bees produce buzzing with their wings up to ten times more noise than they do in normal conditions, a behavior that is usually used by the colony an alarm signal is urgent to abandon the hive.
However, when the alarm ringing is induced by a mobile and not by natural causes, the colony is hopelessly disoriented and with tragic results. Favre's study corroborates other research conducted in 2008 (whose results, then, were inconclusive) according to which the bees were not returning to their hives if they are placed near a mobile phone.
That kind of strong buzz, Favre said, "is not common among bees, and when it occurs, usually does not emit more than two members of the colony at once. The induction, by fields Magnetic mobile phones cause this buzzing alarm can have tragic consequences for the colony. " Alarm signal
mass According to the researcher, "the active mobile terminals have a dramatic impact on the behavior of bees, and that induce workers to cast massively alarm. Normally, that buzzing swarm announced that starts or is a strong signal indicating a problem in the colony. Other factors such as pesticides, the signals emitted by mobile phones and mobile phone masts could be contributing to the disappearance of bees worldwide. I appeal to the international scientific community to undertake further studies in this field. "
As we well know, bees play a key role in the diet of humans. In fact, they are responsible for pollinating at least one hundred seventy of the staple crops are staple diet of billions of people around the world.
The problem of colony collapse (CCD by its acronym in English) was first detected in 1972, but it was not until 2006 that the mass disappearance of hundreds of millions of bees throughout the world made sounded the alarm. Bees, in fact, seemed to "evaporate" everywhere, leaving the hives without a trace.
That year, beekeepers from around the world reported the loss of between 30% and 90% of their colonies. In subsequent years, and to the worsening problem, there have been numerous investigations to identify the source a crisis is not limited only to the bees.
And if they disappear, scientists say, humanity does not survive.
