The honeybee is one of the most important links in the food production chain. In the environment of bee life, there are many threats that they have to face. Among them, we can distinguish pesticides, climate change, and predators. The intensive development of technology resulted in filling the natural environment with E-field of various frequencies and intensities. The study investigated the effect of the E-field with a frequency of 50 Hz at various intensities on the antioxidant system of the honeybee. The exposure of the bees lasted 12 h. The activity of the antioxidant system was investigated in hemolymph collected from young bees. Research has been undertaken in this direction because research by other authors has taken years to stimulate this system through the E-field. The superoxide dismutase (SOD), Catalase (CAT), and total antioxidant potential (FRAP) activity as major antioxidant enzymes were characterized. Research showed changes in the activity of SOD, CAT, and FRAP in all tested groups compared to the control group. The study of E-field appearing in the life of a honeybee enables an understanding of the impact of this factor on its functioning because food production depends on the integrity of this pollinator.
