Abstract

Overview

The study focuses on the developmental effects of radio-frequency electromagnetic fields (RF-EMFs) on the Blue Bottle Fly (Calliphora vomitoria, CV), utilizing advanced RF-EMF dosimetry and experimental exposure approaches.

Purpose

• This study aimed to explore the developmental impacts of RF-EMFs on the Blue Bottle Fly at 5.4 GHz, employing both numerical RF-EMF dosimetry with 3D anatomical models and experimental RF-EMF exposure.

Materials and Methods

The model organism selected was CV, known for its developmental sensitivity to temperature changes and a significant pupal stage suitable for RF-EMF exposure. Advanced micro-CT scanning techniques provided detailed 3D models for accurate dosimetry simulation. An exposure setup involving 400 pupae divided into exposed, sham, and control groups was implemented to compare developmental progress across varying RF-EMF levels.

Findings

• The development metrics such as mass, length, and diameter were similar across all groups.
• Different levels of RF-EMF exposure affected the rate of pupal emergence variably, with one level reducing overall emergence rate compared to control.
• Exposure conditions influenced the timing of emergence, with certain RF-EMF levels delaying or accelerating development relative to controls.

Conclusion

The study highlighted potentially significant effects of RF-EMF on insect development, suggesting that certain exposure levels could disrupt normal developmental timelines. Although all groups showed similar physical development parameters, the variations in emergence timings indicate a need to reassess current RF-EMF safety guidelines to consider its broader biological impacts across different species.
