Changes in Honeybee Behavior Parameters under the Influence of the E-Field at 50 Hz and Variable Intensity

Abstract

Overview

EM-fields, originating from both natural and anthropogenic sources, pose potential risks to wildlife, including insects such as honeybees. This research focuses on the effects of electric fields at a specific frequency and variable intensities on honeybee behavior.

Findings

• Study investigates the behavior of honeybees under the influence of an electric field (E-field) at 50 Hz and different intensities.
• Bee exposure durations were 1 h, 3 h, and 6 h at intensities of 5.0 kV/m, 11.5 kV/m, 23.0 kV/m, and 34.5 kV/m.
• Control group bees were exposed to an E-field of <2.0 kV/m.
• Key behaviors observed included walking, grooming, flight, stillness, inter-individual contact, and wing movements.
• Initial exposure resulted in decreased duration and occurrences of behaviors; prolonged exposure led to a behavioral normalization or increase.

Conclusion

The study highlights significant changes in behavior due to exposure to electromagnetic fields. Extended exposure alters behavioral patterns, potentially indicating adaptive responses or serious disturbances which could have ecological consequences.
