Radiofrequency electromagnetic fields reduce bumble bee visitation to flowers

Research RF Safe Research Library Jan 1, 2025

This blinded, two-year study examined whether RF-EMF exposure at 2.4 and 5.8 GHz affects pollinator visitation to Salvia and Lavandula. The authors report no significant effect on honey bee visitation rates. They report a significant reduction in bumble bee visits per observation period under RF-EMF exposure, which they frame as a potential risk warranting further long-term research.

Perspectives on terahertz honeybee sensing

Research RF Safe Research Library Jan 1, 2025

This paper describes measurements and simulations to support terahertz (THz) sensing of European honey bees for environmental monitoring. It reports dielectric characterization of bee body parts across 1–500 GHz, scattering-based validation of 3D-printed bee mockups, and THz imaging demonstrating detailed anatomical visualization. The work includes dosimetric simulations at 300 GHz to evaluate feasibility of non-invasive, continuous monitoring and notes potential relevance to assessing high-frequency EMF impacts on insect health and habitat safety.

The Influence of an Electromagnetic Field at a Radiofrequency of 900 MHz on the Behavior of a Honey Bee

Research RF Safe Research Library Jan 1, 2025

This laboratory study examined whether a 900 MHz radiofrequency electromagnetic field (RF-EMF) influences the behavior of newly emerged honey bee workers. Compared with controls, the exposed groups showed behavioral changes, with some parameters showing statistically significant differences seven days after exposure. The authors frame RF-EMF as a potential environmental stressor and call for further research, including gene expression analyses.
