Latest Research on Varroa, Monitoring and Control Alternatives with Dr. Ernesto Guzmán-Novoa - PRIMICIAS Dr. Ernesto Guzmán-Novoa, renowned beekeeping researcher and bee health specialist, has led important studies on Varroa destructor, one of the greatest enemies of honey bees worldwide. His recent research has opened new perspectives for the monitoring and control of this devastating pest, offering sustainable and effective alternatives for beekeepers. Key Points of his Research Genetics and Natural Resistance Dr. Guzmán-Novoa has worked extensively on the identification of Varroa-resistant bee colonies. His research has shown that certain characteristics, such as hygienic behavior and mite-scavenging ability (VSH, Varroa Sensitive Hygiene), can be genetically selected to strengthen colonies. These bees remove infested larvae, interrupting the reproductive cycle of the mite. Advanced Monitoring Techniques A crucial part of Varroa control is constant monitoring. The team led by Guzmán-Novoa has developed practical methods to measure Varroa loads in colonies, using innovative technologies such as thermal imaging cameras and molecular analysis, which allow for early and accurate detection. Biological Control Alternatives Among the non-chemical alternatives that Dr. Guzmán-Novoa has explored, the following stand out: Entomopathogenic Fungi: These organisms, such as Metarhizium and Beauveria bassiana, directly attack Varroa without affecting bees. Natural Acaricides: They are investigating plant extracts and essential oils that effectively reduce mite populations without generating resistance. Integrated Pest Management (IPM) Proposes a combined approach, where techniques such as the use of drone traps, heat treatments and rotation of acaricidal products are integrated to minimize mite resistance and maximize effectiveness. Implications for Global Beekeeping Dr. Guzmán-Novoa’s work represents a significant step towards a more sustainable and resilient beekeeping. His contributions not only offer immediate solutions for managing Varroa, but also emphasize the importance of applied research and collaboration between beekeepers and researchers. “The key is in the diversification of tools and in a deep understanding of the biology of the bee and its enemy, Varroa. Only in this way can we guarantee the health of our hives in the future,” said Dr. Guzmán-Novoa at a recent international conference. This note summarizes the relevance of current research and reminds us that scientific knowledge is essential to face the challenges that affect global beekeeping.
