Bee Spaced #11 : Breakthroughs and Breakdowns
This week’s digest lands at a strange inflection point for our industry — a week where the science has never looked more promising and the institutional support has never looked more fragile.
Let’s start with the good news, because it’s genuinely extraordinary. A team at Oxford, publishing in Nature, has engineered a yeast-based supplement that provides bees with six essential sterols they normally get from pollen. In controlled trials, colonies on this diet produced 15 times more brood than those on conventional pollen substitutes. Fifteen times. Colonies without the sterols stopped rearing brood entirely after 90 days. If this holds up in field trials — and the researchers say it could be commercially available within two years — it would fundamentally change how we feed bees through dearth periods and poor forage seasons. Pair that with Washington State’s work showing human-made pollen replacements can sustain colonies through winter at commercial scale, and the nutrition picture for managed bees is shifting fast.
On the disease front, new research in Biology Letters shows that individual honey bees vary widely in their ability to detect viruses in food — some avoid contaminated sources, others don’t. That kind of variation matters when we think about natural disease resistance within a colony. Meanwhile, a separate study found that pathogens we typically associate with managed hives are showing up widely in wild bee populations, reinforcing the spillover risk as hive densities increase.
A story that really got my attention is #5 that looks at PFAS found in honey. There’s a video in the article that tells the story of how a Belgian family has been affected by these chemicals.
Closer to home for Canadian beekeepers, CBC ran a story this week on Brendan Daisley’s work at the University of Guelph. His Canadian Bee Gut Project is profiling the microbiomes of honey bees from coast to coast, and the team is now zeroing in on queen bees specifically — comparing the gut health of queens that overwinter successfully with those that don’t. Canada imports up to 300,000 queens every year from warmer climates, and the Ontario Beekeepers’ Association reports that imported queens are more vulnerable to stress and disease. If Daisley’s team can connect microbiome profiles to overwintering success, it could open the door to microbiome-informed rearing practices that help us grow more resilient domestic stock. This is exactly the kind of Canadian research that deserves attention.
And then there’s the story that should concern every beekeeper on this continent. The Trump administration is moving to close the USDA’s Beltsville Agricultural Research Center — the facility that stepped in after last year’s catastrophic die-off and identified pesticide-resistant mite-vectored viruses as the likely cause. Beltsville has been the place beekeepers turn when disaster strikes. Its closure, at a time when the industry has never been more stretched, would leave a hole in federal bee research that no university lab can easily fill.
On a practical note for American beekeepers, the 2025-2026 U.S. Beekeeping Survey is open now through the end of April — if you keep bees south of the border, please take 15 minutes to fill it out. And Texas A&M AgriLife is running beekeeping field days in April and May, including a queen rearing course.
As always, I’d love to hear what’s happening in your yards this spring.
Diseases & Pests Research
1. 🔬 Anthropogenic stressors drive microbiome assembly: A global meta-analysis of bumble bees
Source: The Science of the Total Environment — April 2026 | Authors: Macpherson, Daisley, Drosdowech et al.
A global meta-analysis exploring how human-caused stressors — including pesticides, habitat loss, and urbanization — shape the microbial communities in bumble bee guts. The microbiome is increasingly recognized as a key factor in bee health and resilience, and this study maps how it changes under pressure. Relevant to anyone thinking about the connection between environmental stress and colony health.
2. 🔬 Attraction versus avoidance: honeybees vary in response to virus-contaminated food
Source: Biology Letters — April 2026 | Authors: Payne, McCarthy, Castillo et al.
Can honey bees detect viruses directly in food? This study tested whether bees show attraction or avoidance when offered virus-spiked sucrose solutions. The results were mixed — some bees avoided contaminated food while others did not, suggesting individual variation in pathogen detection. Understanding these behavioral responses could inform disease management strategies in apiaries.
3. 🔬 Widespread distribution of honey bee-associated pathogens in managed and wild bees
Source: Die Naturwissenschaften — April 2026 | Authors: Capela, Tiritelli, Sarmento et al.
Researchers found that pathogens commonly associated with managed honey bee colonies are widespread among wild bee populations as well. This highlights the risk of pathogen spillover between managed and wild bees — a growing concern as urban beekeeping expands and hive densities increase near wild pollinator habitats.
4. 🔬 Flexible, abstract rhythm perception in bumble bees
Source: Science — April 2026 | Authors: Zeng, Barron, Peng et al.
Published in Science, this study demonstrates that bumble bees can perceive and discriminate abstract rhythmic patterns — a cognitive ability previously documented only in a few birds and mammals. Free-flying bees learned to distinguish between different flashing light sequences and could generalize to new patterns. While not directly about colony management, it underscores the remarkable cognitive complexity of the insects we work with.
5. “Forever chemicals” found in honey: What it means for your health and food supply
Source: Natural News — April 1, 2026
A study found that PFOS, a type of PFAS “forever chemical,” can accumulate in both honey and honeybees. PFAS compounds don’t break down easily in the environment and can build up in biological tissue over time. This is a consumer-facing story worth tracking — public concern about contaminants in honey could have market implications for beekeepers.
Colony Health & Nutrition
6. Replacing pollen with ‘granola bars’ is good for honey bees
Source: Futurity / Washington State University — March 31, 2026
Washington State researchers demonstrated that a human-made food source provided honey bees a nutritious diet at commercial scale over two winter seasons. As natural pollen availability declines in many regions, practical supplemental feeding options are becoming essential for colony survival through winter.
7. Oxford researchers engineer bee “superfood” — colonies produce 15x more brood
Source: ScienceDaily / Nature — March 27, 2026
This is a landmark study. University of Oxford researchers, working with Kew Gardens and the Technical University of Denmark, used CRISPR gene editing to engineer yeast that produces six essential sterols bees normally get from pollen. In controlled trials, colonies fed this supplement produced up to 15 times more larvae than those on conventional pollen substitutes. Colonies without the sterol supplement stopped producing brood after ~90 days. The supplement could be commercially available within two years. Published in Nature.
Industry News
8. USDA Beltsville bee lab faces closure amid record colony losses
Source: Nebraska Public Media / Harvest Public Media — April 6, 2026
The Trump administration plans to close the USDA’s Beltsville Agricultural Research Center — the nation’s premier bee research facility. This is the same lab that identified viruses spread by pesticide-resistant mites as the likely cause of 2025’s massive colony die-off (1.6 million colonies lost). Former Beltsville researcher Jeff Pettis called the timing alarming, noting the industry has never been more stretched to keep healthy bees. The proposed closure raises serious questions about the future of federal bee research in the U.S.
9. 2025-2026 U.S. Beekeeping Survey now open
Source: Apiary Inspectors of America — April 2026
The annual U.S. Beekeeping Survey is now accepting responses through the end of April. All beekeepers — hobbyist to commercial — are encouraged to participate. The data feeds directly into long-term colony loss tracking and helps shape federal and state support for the industry. If you keep bees in the U.S., take 15 minutes and fill it out.
10. Texas A&M AgriLife hosting Beekeeping Field Days — April & May 2026
Source: Kilgore News Herald / Texas A&M — April 3, 2026
Texas A&M AgriLife Extension is running hands-on beekeeping workshops this spring, including Beekeeping 101, Beekeeping 201, and a Queen Rearing Course. Events are in Overton (April 11), Lubbock (April 18), and McGregor (May 2). Space is limited — register early.
Canadian Beekeeping
11. Understanding bee gut health may be the key to producing more resilient colonies and queens
Source: CBC News — April 6, 2026
University of Guelph postdoctoral fellow Brendan Daisley is leading the Canadian Bee Gut Project — a nationwide effort to profile the microbiome of honey bees through thousands of samples from commercial beekeepers across the country. The project is now expanding to focus specifically on domestic queen bees, comparing the microbiomes of queens that successfully overwinter with those that don’t. Canada imports up to 300,000 queen bees annually from warmer climates, and the Ontario Beekeepers’ Association notes that imported queens are more vulnerable to stress and often have weaker immune systems from long-distance travel. Daisley’s work aims to develop microbiome-informed rearing practices that could help grow Canada’s domestic queen stock and reduce reliance on imports. Ontario beekeepers lost more than a third of their colonies in 2025.
