A cornerstone of federal pollinator research in Maryland is winding down as the U.S. Department of Agriculture moves forward with plans to decommission the Beltsville Agricultural Research Center. The decision comes at a difficult time for the beekeeping industry, which is grappling with unusually high colony losses and ongoing threats to honey bee health.
The Beltsville Bee Research Laboratory, located within the sprawling 6,500-acre center in Prince George’s County, has long served as the nation’s premier facility for bee research and disease diagnosis. For decades, scientists there have investigated colony collapse disorders, varroa mite resistance, viral pathogens, and other challenges facing managed honey bees. Beekeepers and state inspectors across the country, including in Maryland, have relied on the lab for rapid sample analysis and expert guidance when colonies show signs of trouble.
David Schultz, president of the Maryland State Beekeepers Association and an apiary inspector with the Maryland Department of Agriculture, said the lab’s diagnostic work has been essential for responding to emerging threats. He noted that inspectors regularly submit samples from hives showing unusual symptoms, and the Beltsville team has provided timely results that help beekeepers adjust management practices. Without that resource, Schultz warned, the ability to diagnose and treat problems quickly could suffer, especially for smaller operations and new beekeepers who depend on mentorship and technical support.
Recent colony losses have heightened concerns. Many Maryland beekeepers reported winter losses exceeding 60 percent during the 2025-2026 season, well above the typical range of 25 to 30 percent. These steep declines have been linked in part to pesticide-resistant varroa mites and associated viruses. Schultz pointed out that the timing of the lab’s closure is particularly problematic because beekeepers are still recovering from those setbacks while trying to rebuild their operations.
Honey bees play a critical role in agriculture, pollinating more than 130 crops and contributing an estimated $15 billion annually to U.S. crop production, according to USDA figures. In Maryland, managed honey bees support a range of fruit, vegetable, and specialty crops. Schultz emphasized that losing pollinators would not only reduce yields but could also have broader effects on food availability and prices, given the state’s role in regional agriculture and the Chesapeake Bay watershed.
The USDA has described the decommissioning of the Beltsville center as part of a larger reorganization aimed at improving efficiency and relocating research closer to the farmers and stakeholders it serves. Officials have cited the need for major repairs and modernization at the aging facility, which includes hundreds of buildings, many of which are underutilized or in poor condition. Research programs are being moved to other Agricultural Research Service locations across the country, with projects reassigned based on regional agricultural needs.
Critics, including members of Maryland’s congressional delegation and industry groups, argue that the move disrupts vital ongoing work and could slow responses to future crises. They note that the lab has played a unique role in the mid-Atlantic region, where climate and pest pressures differ from those in other parts of the country. Schultz highlighted that beekeepers often function like veterinarians for their hives, needing quick, reliable diagnostics to identify what is affecting colonies and how to address it. Losing a centralized, experienced diagnostic hub, he said, removes a key layer of support that is difficult to replicate elsewhere.
The closure also raises questions about the future of beekeeping education and community outreach in Maryland. Schultz regularly works with hundreds of new and aspiring beekeepers through mentoring programs and partnerships with higher education institutions. These efforts rely on access to accurate information and diagnostic services that the Beltsville lab has provided. Without that infrastructure, he warned, the pipeline of new beekeepers and the overall resilience of the industry could be affected for years.
While the USDA has stated that research will continue at other facilities, beekeepers and scientists worry about the loss of institutional knowledge, specialized equipment, and the ability to conduct rapid, on-the-ground investigations during outbreaks. Historical sample collections and long-term studies housed at Beltsville also face an uncertain future as operations wind down.
For Maryland’s agricultural community, the changes at Beltsville come as pollinator health remains a pressing concern. Beekeepers continue to adapt to varroa mites, viruses, habitat loss, and other stressors, while farmers depend on reliable pollination services for many high-value crops. The loss of a dedicated federal bee research and diagnostic center could make it harder to stay ahead of emerging threats.
Officials have indicated that the decommissioning process will take place over several years, with research projects transitioning gradually. Beekeepers and agricultural stakeholders are watching closely to see how the relocation of programs affects day-to-day support and long-term research capacity.
The situation underscores the challenges of balancing federal budget priorities with the need for robust scientific infrastructure to protect vital parts of the food system. As Maryland beekeepers work to rebuild after difficult seasons, the future of the specialized resources that have supported them remains uncertain.
