Abstract

During the New Year’s Eve 2019, a microphone was placed in a hive, in order to analyze the potential changes in the acoustic behavior of the honeybees. It turned out that the honeybees produced worker piping signals, which are usually signals that are produced shortly before takeoff of a swarm, or are the sign of a disturbed colony. This behavior was solely observed during this peculiar night. It is hypothesized that planetary enhancement of electromagnetic radiation produces a disturbing pollution for honeybees, such as during the New Year’s Eve night.

Methods

The device employed for the recording of the honeybees’ sounds consisted of a bidirectional compact microphone (Olympus ME-31) with frequency response from 70 to 15,000 Hz connected to a vocal recorder (Olympus LS-11). The microphone was placed in the bottom part of the hive.

The vocal recorder was connected to an external battery (Panasonic LC-R123R4P ; https://na.industrial.panasonic.com/) via a 12V-to-4.5V voltage converter (Dupertuis Electronique S.A., Lausanne, Switzerland).
