Abstract

Overview

The study investigates the impact of extremely low frequency (ELF) magnetic fields on Drosophila subobscura isofemale lines, revealing potential health implications and responses dependent on genetic variability.

Purpose

  • Investigate the effects of ELF magnetic fields on fitness components and locomotor activity in different genetic lines of Drosophila subobscura.

Materials and Methods

Research involved exposure of D. subobscura isofemale lines to ELF magnetic field (50 Hz, 0.5 mT, 48 h). The study specifically focused on:

  • Genetic structures based on mitochondrial DNA variability.
  • Observations of fitness components and locomotor activity in an open field test post-exposure.

Findings

  • Developmental time was shortened in egg-first instar larvae exposed to ELF magnetic fields.
  • No significant effects on viability and sex ratio were observed.
  • Demonstrated decreased locomotor activity in IF lines B16/1 and B24/4, with extended effects in females.

Conclusion

The results underscore diverse responses to ELF magnetic fields across different genetic backgrounds of Drosophila subobscura, highlighting critical considerations for ecological and health-related assessments of ELF magnetic field exposure.
