Honey Bee Viruses with Declan Schroeder (362)

This week on Beekeeping Today Podcast, Becky welcomes guest co-host Bridget Mendel as they sit down with virologist Dr. Declan Schroeder from the University of Minnesota's College of Veterinary Medicine. Together, they explore the unseen world of honey bee viruses—how they evolve, how they spread, and why understanding them is essential for modern beekeeping. Declan brings a fresh perspective to virus ecology, sharing how his early research on marine viruses led him into honey bee health just as colony losses began escalating worldwide. He describes why viruses were overlooked for so long and how the arrival of Varroa shifted viral dynamics from background agents to major colony-level threats. Becky and Bridget dig into what this means for beekeepers: why Varroa management remains the cornerstone of reducing virus pressure, how viruses move within and between colonies, and what new research is revealing about potential spillover concerns between honey bees and native bees. Declan discusses findings from a multi-year Minnesota study showing that while bumblebees may encounter honey bee viruses, they are rarely infected—an important distinction in ongoing conservation conversations. The discussion wraps with a look ahead: evolving virus–vector interactions, improved surveillance efforts, and the growing role of researchers and veterinarians in supporting beekeeper decision-making. It's an engaging, approachable dive into a complex subject—one that every beekeeper will benefit from hearing.
