It’s a that the world honeybee population is in decline the globe. Scientists have various possible explanations as to why, cold weather, genetically-modified crops, and viruses. They have now mobile phones to the list of possible bee killers. Swiss researchers have done a on what is known as Colony Collapse Disorder, a phenomenon in which worker bees desert the hive, never to . This situation leads to the end of the colony because the queen bee out of food. Lead researcher Daniel Favre says his study a relationship between the growing of cellphones and declining bee populations. Favre notes that earlier studies failed to find any such link and thus accepts his are “highly controversial”.

Favre’s study analyzed bee sounds in five beehives in two different places in Switzerland. He the bees' sounds with mobile phones in the hive. The bees were monitored when the mobile phones were and inactive. Scientists analyzed the sounds of the bees and discovered they weren't by mobile phones that were inactive or on . However, active and cellphones confused the bees and caused them to fly from and leave the hive. The study says "the behavior of the bees remained perturbed for up to 12 hours after the of the prolonged mobile phone communication," Favre writes. "This observation means that honeybees are to…electromagnetic fields by the mobile telephones."
