“RF EMFs Reduce Bumble Bee Visitation to Flowers,” Environmental Pollution, July 14, 2025.
No effect of 2.4 & 5.8 GHz RF on flower visitation rates by honey bees. But there was a “significant reduction” in visits by bumble bees when the plants were exposed to the RF.
The exact mechanism “is not yet clear.” The research was self-funded.
From Germany.
