Active mobile phone handsets placed near honeybees induced worker piping, a signal associated with swarming or colony disturbance.

Plain English Summary

Summary written for general audiences

Researchers placed mobile phone handsets in the close vicinity of honeybees and recorded and analyzed the sounds the bees made. The audiograms and spectrograms revealed that active mobile phone handsets have a dramatic impact on the behavior of the bees, namely by inducing the worker piping signal. In natural conditions, worker piping either announces the swarming process of the bee colony or is a signal of a disturbed bee colony.

Why This Matters

The study used audiograms and spectrograms to analyze bee sounds when mobile phone handsets were active nearby. Worker piping is a naturally occurring bee signal that in normal circumstances either announces swarming or indicates a disturbed colony.
