In a 2023 webinar, Colm ÓNéill presented his insights into sustainable beekeeping practices centred around the preservation and use of native bees, specifically the Apis mellifera mellifera (AMM), or the European Dark Bee. This approach emphasizes the importance of local adaptation, strategic management for high population density, and natural resilience against pathogens, aligning closely with the Sustainable Honey Bees CIC ethos and the B4 project in the UK, which advocates for the AMM. Here’s a summary of the key takeaways from Colm’s webinar, which provides both practical advice and theoretical background on enhancing native bee populations for honey production and colony health.
Embracing Local Adaptation and Avoiding Imports
Colm stresses the significance of using locally adapted bees rather than imported ones. Imported bees often bring genetic introgression, which weakens the local gene pool, undermining the adaptations that have developed over generations in the local climate. This aligns with recent genetic studies suggesting that outbreeding depression can compromise honeybee health and productivity by disrupting these locally adapted traits.
He emphasizes that native bees, through natural selection, are better suited to handle regional challenges, from climate conditions to pests like the Varroa destructor. The selective pressures in specific environments shape a bee’s resistance to local diseases and climate, making them inherently more resilient than non-native or hybridized bees.
High Population Density and Brood Management
ÓNéill’s method focuses on managing colonies to sustain high population densities throughout the season. High colony numbers ensure a productive workforce during honey flows and support strong genetic diversity through natural selection. This approach involves regular brood rotation, which minimizes pathogen build-up in the hive, helping reduce Varroa load and enhancing colony resilience without chemical treatments.
Brood management also plays a key role in ÓNéill’s strategy. By rotating brood frames and ensuring space for expansion, beekeepers can support population growth and reduce swarm tendencies naturally. This practice reduces the need for artificial swarming controls, thus maintaining a robust hive throughout the season.
Selective Breeding for Disease Resistance and Non-Swarming Behavior
Selective breeding is central to Colm’s approach. He advocates for selecting queens and drones that display desirable traits, particularly disease resistance and non-swarming behavior, both of which can reduce the need for intervention. Non-swarming bees maintain stable population levels, which is advantageous for honey production and reduces disruptions during the active season.
Selective breeding also enhances the genetic traits that support natural Varroa resistance, such as hygienic behavior and grooming. Research on naturally Varroa-resistant populations, like those on the Gotland island, demonstrates how selection for these behaviors can sustain bee health without chemical treatments.
Reducing Chemical Interventions
Consistent with sustainable beekeeping, ÓNéill advocates minimizing chemical treatments. Chemical-free approaches are more sustainable and preserve the natural behaviours necessary for long-term colony resilience. This aligns with the principles of Integrated Pest Management (IPM), which combines various strategies to keep pest levels below harmful thresholds, including physical controls like open mesh floors and drone brood removal.
Education and Community Engagement
Colm stresses the importance of beekeepers educating themselves on sustainable practices and engaging with the local beekeeping community to support shared goals. He highlights the collective responsibility in beekeeping to protect native bee genetics and maintain the health of bee populations. Through community initiatives like the B4 project, beekeepers can contribute to a regional effort that prioritizes sustainability and resilience over short-term gains from imports.
Conclusion
Colm ÓNéill’s webinar offers a blueprint for beekeepers aiming to increase honey yield and colony health through sustainable practices focused on native bees. His emphasis on local adaptation, high population management, selective breeding, and minimal intervention aligns well with a broader movement in beekeeping toward environmentally conscious and resilient apiary management. Embracing these principles not only benefits beekeepers but also supports biodiversity, ecological balance, and long-term sustainability in beekeeping.
