Potential of Wormwood and Oak Bark-Based Supplement in Health Improvement of Nosema ceranae-Infected Honey Bees

Summary

This study tested a natural dietary supplement made from wormwood and oak bark on honey bees infected with Nosema ceranae, a parasite that weakens bee colonies. The supplement significantly improved bee survival and reduced parasite levels, regardless of when it was given. It also reduced harmful oxidative stress caused by the infection. While it didn’t boost immune genes as strongly as some other treatments, its plant-based nature and consistent effectiveness make it a promising tool for beekeepers.

Background

Nosema ceranae is a microsporidian parasite that negatively impacts honey bee longevity, productivity, and reproductive capacity. Current treatment options are limited, with fumagillin being compromised due to contamination risks and genotoxic potential. Natural plant-based supplements offer a promising alternative for nosemosis control.

Objective

To test the potential of a wormwood and oak bark-based dietary supplement (Medenko forte) for Nosema ceranae infection control and health improvement in honey bees. The study evaluated effects on bee survival, Nosema infection levels, oxidative stress, and immune-related gene expression.

Results

The supplement significantly improved survival of Nosema-infected bees regardless of administration timing. Nosema spore loads were significantly reduced in treated groups compared to infected controls on days 9 and 15. Oxidative stress parameters were generally lower in treated groups, and immune gene expression was higher in treated groups compared to infected controls, though less pronounced than other supplements.

Conclusion

The tested wormwood and oak bark-based supplement demonstrates significant anti-Nosema potential and reduces Nosema-induced oxidative stress in honey bees. While it shows lower immunostimulatory effects compared to some alternatives, its effectiveness regardless of administration timing and plant-based nature make it valuable for beekeeping, though further research is needed to elucidate mechanisms of action.
