# Exposure to 5G-NR electromagnetic fields affects larval development of Aedes aegypti mosquito

## TL;DR

Exposure to 5G-NR electromagnetic fields slows the development of Aedes aegypti mosquito larvae, especially under poor nutrition.

## Contribution

This study experimentally demonstrates that 5G-NR RF-EMF exposure affects mosquito larval development.

## Key findings

- At 46.2 V/m exposure, mosquito larvae developed more slowly, particularly those with poor nutrition.
- At 182.6 V/m exposure, dielectric heating altered development timing and adult size.
- A custom reverberation chamber was used to expose larvae to controlled RF-EMF levels.

## Abstract

Telecommunication networks, including 5G New Radio (5G-NR), emit these fields and consequently expose many insects. To quantify the potential effect of RF-EMF exposure on insects, a study was designed examining the development of the Aedes aegypti mosquito, a major vector of dengue and other pathogens, as model organism exposed to RF-EMFs at 3.6 GHz. A custom exposure setup, a reverberation chamber, was designed, built, and characterized. Numerical simulations made it possible to calculate doses received by the larvae during the exposure. Larvae were reared on two feeding regimes, differing in nutritional value, and exposed for 5 days. At an RF exposure level of 46.2 V/m and absorbed power of 1.2 \documentclass[12pt]{minimal}
