Abstract

Overview

The study explores how extremely low-frequency electromagnetic fields (ELF EMFs) affect locust flight. Specifically, it investigates the behavioral and physiological impacts of ELF EMFs on insects, with a focus on locusts subjected to acute EMF exposure.

Findings

• Locusts tethered between copper wire coils, with EMFs generated at various frequencies, were analyzed via high-speed video recording.
• The mean wingbeat frequency of tethered locusts was measured at approximately 18.92 Hz.
• Exposure to a 50 Hz EMF led to significant changes in wingbeat frequency, with variations depending on the initial flight frequencies of the locusts.
• Locusts exhibited a wingbeat frequency entrainment, matching frequencies close to the EMFs applied, suggesting a strong influence of EMFs on insect flight dynamics.

Conclusion

The application of ELF EMFs resulted in small yet significant modifications in locust wingbeat frequency. The study underscores the potential biological implications of EMFs on insect flight coordination, indicating a sensitive interaction between electromagnetic exposure and physiological responses in flying insects.
