Abstract

Overview

Increasing urbanization and wireless technology usage have heightened the emission rates of radiofrequency electromagnetic fields (RF-EMF), affecting the natural behavior of bees and other insects. This study explores the impact of RF-EMF on honey bees, focusing on their homing abilities and other vital parameters.

Findings

  • RF-EMF exposure significantly reduced the homing success of honey bees, particularly after long-term exposure. However, it didn't affect brood development or longevity.
  • The study simulated RF-EMF exposure using 2.4 and 5.8 GHz bands, representative of typical wireless device frequencies, to explore its effect under realistic field conditions.
  • High-quality radiation sources from the Communications Engineering Lab at Karlsruhe Institute of Technology were utilized to ensure consistent and definable electromagnetic radiation exposure.

Conclusion

RF-EMF exposure acts as a sublethal stressor on honey bees, diminishing their homing success and causing a potential loss in forager bees. This highlights a critical need for further investigation into the nuanced impacts of electromagnetic radiation on bee populations and possibly other wildlife.
