Abstract

Overview

Electromagnetic fields (EMFs), omnipresent in the modern environment, are largely emanating from various human-made sources like transmission lines. The health implications of these fields, particularly at extremely-low frequencies (ELF), are not well understood despite their ubiquitous presence.

Findings

• Research utilizing the nervous system of locusts has indicated significant behavioral and physiological alterations upon exposure to high levels of ELF EMFs (>4mT).
• Key observations include reduced locust mobility, increased spike latency and wider spikes in neural activity, specifically in the fast extensor tibiae motor neuron.
• Additionally, stimulation of the extensor tibiae muscle showed decreased kick force in the hind legs of affected insects, alongside an increase in stress-related protein levels (Hsp70).

Conclusion

This study underscores the profound impact ELF EMF exposure can have across multiple biological levels, ranging from behavior to protein expression. It establishes a crucial foundation for future explorations into the ecological ramifications for other flying insects experiencing similar exposure.
