Honey Bee Proteolytic System and Behavior Parameters under the Influence of an Electric Field at 50 Hz and Variable Intensities for a Long Exposure Time

Abstract

Overview

The growing concern about the environmental impact of artificial electromagnetic fields (EMFs) has led to numerous studies, including this investigation into how these fields affect honey bees. This study specifically examines the effects of a 50 Hz electromagnetic field on the proteolytic systems and behavior parameters of honey bees over a long exposure time.

Findings

• Experimental Setup: Newly emerged worker bees were kept under exposure to varying intensities of a 50 Hz electromagnetic field. Intensities tested were 5.0 kV/m, 11.5 kV/m, 23.0 kV/m, and 34.5 kV/m over a 12-hour period.
• Behavioral Effects: Compared to control bees, those exposed to the electromagnetic field showed decreased occurrences of walking, self-grooming, and contact between individuals.
• Biological Changes: An increase in protease activity suggests a significant biochemical response in bees exposed to the electromagnetic field.

Conclusion

The presence of an artificial electromagnetic field may pose potential harm to honey bees, as evidenced by altered behaviors and increased protease activities, which are part of the immune system response. Further research is needed to assess the duration and persistence of these effects post-exposure.
