This animal ecology study reports that weak anthropogenic-like airborne electric fields can reduce honeybee floral landing rates. It reports deterrent effects for AC and positive DC fields, with no statistically significant effect for negative DC fields. The authors also report that electric fields measured near high-voltage power lines can match the levels that affected bees and extend tens of meters at foraging-relevant heights.

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.
