Abstract

Overview

This study assesses the impact of electromagnetic fields (EMF) on the pollination efficiency of honeybees through a series of field and laboratory experiments.

Findings

  • Analysis of gene and protein expression showed significant physiological stress in honeybees exposed to EMF, with enhanced expression of heat-shock proteins and antioxidant activity genes.
  • Behavior-related gene expression was also significantly affected by EMF exposure.
  • The study observed a decrease in honeybee visits and seed production in California poppy plants situated near sources of EMF. These plants received fewer visits and produced fewer seeds compared to those in areas with lower EMF exposure.
  • A hump-shaped relationship was identified between EMF and plant species richness and abundance, indicating complex ecological impacts.

Conclusion

Damaging impacts of EMF were clearly seen on honeybee pollination behavior which in turn negatively affected the plant community. This could partly explain the global pollination crisis impacting crop production.
