"This study shows that the presence of an active mobile phone disturbs bees -- and has a dramatic effect," Favre told the Daily Mail.
Favre believes this to be evidence of something other scientists have suggested: Signals from mobile phones are contributing to the decline of honeybees. Favre thinks more research could help confirm the link between cell signals and "colony collapse disorder" -- the sudden disappearance of entire colonies over winter -- which has halved the bee population, according to some estimates.
"We have 50 species of bumble bees in North America. We've studied eight of them and four of these are significantly in trouble," said University of Illinois entomology professor Sydney Cameron, who led the study. "They could potentially recover; some of them might. But we only studied eight. This could be the tip of the iceberg," she said.
