Abstract

Overview of the Study

This paper explores the chronic effects observed in Blaptica dubia nymphs when exposed to magnetic fields over a prolonged period of five months.

Methodology and Key Findings

Types of magnetic fields studied: static magnetic field (SMF; 110 mT) and extremely low frequency magnetic field (ELF MF; 10 mT, 50 Hz).
Key biomarkers used for analysis: acetylcholinesterase (AChE) activity and heat shock protein 70 (HSP70) levels.
Results: Significant changes were observed in relative growth rate (RGR) and AChE activity, indicating altered biological responses due to magnetic field exposure.
HSP70 levels increased significantly only under SMF conditions, suggesting a different response mechanism when compared to ELF MF exposure.

Conclusion

The study highlights the biological impact of exposure to different types of magnetic fields on terrestrial insects and suggests potentially hazardous health implications due to chronic exposure to electromagnetic fields.
