Dr. Juliana Rangel, an expert in queen bee biology, provides a comprehensive overview of factors influencing queen bee quality and management. She emphasizes the role of genetics in determining colony traits and underscores the importance of avoiding inbreeding to mitigate issues like diploid drones, which are unviable and usually removed by worker bees. Her lecture also delves into the haplodiploid sex determination system in bees, the detrimental effects of pesticides on drone sperm viability and queen mating success, and the critical role of queen pheromones in maintaining colony structure and inhibiting worker bee reproduction.
Additionally, Dr. Rangel discusses the implications of environmental factors like climate change on beekeeping, highlighting the need for vigilant queen management to ensure healthy and productive colonies. She stresses the importance of monitoring queen age and vigor, suggesting effective management strategies to maintain robust colonies. Concluding her talk, Dr. Rangel promotes an upcoming workshop on queen rearing and encourages attendees to follow her Facebook page for updates on future events and educational opportunities in beekeeping.
