Begin with clear goals. Define desired outcomes such as Varroa resistance, honey yields, winter survival, and calm temperament. These targets shape selection, queen rearing, and daily hive work.
Good records matter. Standardized inspection notes and trait scores let beekeepers compare colonies across yards and seasons. Regular checks and careful record-keeping reveal trends early.
Open mating is common for honey bees, so use instrumental insemination or managed drone sources when control is needed. Screen top colonies and avoid sources with chalkbrood, following advice from Dr. Marla Spivak and Gary Reuter.
Cull clearly poor stock and set simple rules for removal. Treat resistance traits as part of integrated control, not a sole solution. Plan training, budget time, and align selection with local conditions.

Understand Hygienic Breeding Goals and User Intent in the United States
Start with outcome-based targets: set clear aims that link selection to lower varroa growth, reduced viral signs, and reliable winter survival. These goals guide which trait tests you run, when you test, and how you compare colonies across yards.
Why this behavior matters for Varroa and disease control
Hygienic behavior is the rapid detection and removal of compromised brood by worker bees. Colonies scoring ≥95% removal of freeze-killed brood within 24–48 hours are considered highly hygienic. Research shows such colonies accumulate roughly half the varroa mites and display fewer DWV symptoms over one year.
Aligning objectives with local environments and operations
Match targets to your operation—migratory, sideliner, or stationary—because forage, climate, and nearby apiaries affect open mating and trait expression. Open-mated queens from hygienic lines often pass the trait on, but local drone ratios matter.
- Set measurable tests: repeat freeze-killed brood checks during active brood cycles and record cells uncapped and removal percentages.
- Use hygiene as part of resistance: it lowers mites and disease levels but does not replace monitoring or integrated controls.
For national context and coordination, consider strategies in the national pollinator health strategy when aligning goals across regions.
Foundations: Training, Equipment, and Record‑Keeping for a Proven Program
Start with clear, repeatable routines. Train staff and volunteers so each inspection follows the same steps. Consistency makes trait scores meaningful across yards and over years.
Core skills include rapid inspections, trait scoring, and basic queen rearing techniques. Teach grafting, marking queens, and setting mating nucs so replacement cycles stay reliable.
Tools and kits every team needs
Assemble freeze‑killed brood kits, alcohol wash or sugar roll supplies for mite counts, magnifiers for VSH checks, and sticky boards for grooming assessment. Marking pens and clear lineage tags keep queens linked to performance records.
Designing field data sheets
Use a structured sheet that logs temperament, honey stores, brood frames, disease signs, mites per 100 bees, and VSH on fixed dates. Store records digitally and back them up with hive ID, apiary, date, and weather.
| Measure | Unit | Frequency |
|---|---|---|
| Temperament score | 1–5 | Every inspection |
| Honey stores | Frames | Monthly during nectar flow |
| Brood production | Frames of brood | Monthly |
| Mite count | Mites per 100 bees | Every 4–8 weeks |
| VSH / grooming | Percent or score | Seasonal checks |
Timing matters: wait at least six weeks after requeening before testing brood‑care or grooming behavior. Nurse bees must be daughters of the current queen for valid results.
Choose open or closed mating based on capacity. Instrumental insemination gives precision, while managed open mating scales well for most beekeepers. Reference university research and website protocols for field methods and germplasm resources.
How to create a hygienic bee-breeding program
Start with clear, repeatable screening routines that yield comparable results across apiaries. Standardize patch size, timing, and record sheets before testing so each colony can be judged fairly.

Screening with freeze‑killed brood
Use freeze‑killed brood (liquid nitrogen or frozen sections) and score removal at 24–48 hours. Require ≥95% removal on two separate trials before naming any colony a breeder.
Evaluating VSH and grooming
Open capped brood and count reproductive versus non‑reproductive varroa mites. Favor colonies showing only non‑reproductive mites for VSH selection.
Measure grooming by collecting fallen mites on sticky boards and noting damaged legs; use this to find mite‑biting colonies. Exclude recapping from breeding decisions based on current evidence.
Selecting breeder queens and timing tests
Select queens from colonies that score consistently high for hygienic behavior, VSH, grooming, honey, and temperament. Cull queens tied to high mite levels, poor brood patterns, or disease signs.
Schedule tests when brood is abundant and wait at least six weeks after requeening so worker bees reflect the new queen’s genetics.
| Test | Metric | Frequency |
|---|---|---|
| Freeze‑killed brood | Removal % (24–48 hr) | Two trials per season |
| VSH check | Reproductive vs. non‑reproductive mites | Seasonal, during capped brood |
| Grooming | Damaged mite legs on boards | Monthly during active season |
| Mite monitoring | Mites per 100 bees | Every 4–8 weeks |
- Repeat tests across the season and compare within the same apiary and time window.
- Track mite levels before and after selection to link behavior results with practical control outcomes.
- Integrate selection with IPM so resistant traits reduce pressure across colonies as they spread.
Mating Strategies: Open, Closed, and Regional Drone Saturation
Your mating plan balances precision, scale, and the practical limits of local drone populations. Choose the route that fits your goals, workforce, and timeline.
Closed systems with instrumental insemination
Instrumental insemination gives precise control of queen × drone pairings. It requires training, lab-grade syringes, and careful handling of semen.
Use this when you must fix specific genes or anchor a breeding line for the year.
Open mating done right
Open mating scales well for most beekeepers. Success hinges on drone numbers and placement in the local area.
Saturate mating yards by designating apiaries for drone production and offering ripe queen cells to nearby collaborators within 2–3 miles.
Applying additive genetics and regional plans
Introduce VSH and grooming alleles through open mating while keeping local adaptation. Rotate breeder lines each year so queens mate with complementary traits over sequential seasons.
- Record mating locations, weather, and timing.
- Compare resistance and honey metrics for queens and colonies from each strategy.
- Coordinate with breeders and beekeepers to improve drone saturation and results.
Trait Portfolio: Hygienic, VSH, Grooming, and Linked Performance Outcomes
Select a layered trait portfolio that pairs hygienic behavior, VSH, and grooming. This mix improves resistance while protecting honey production and colony stability.
Research shows correlations between higher hygienic scores and stronger adult populations and greater wax and honey yields in some studies. LASI work also suggests these lines can remain calm during inspections and lower Varroa buildup and DWV signs.

Score broadly. Record temperament, foraging, repair behavior, cells and brood pattern along with mite counts. Exclude stock with extreme defensiveness even if mites are low.
- Validate traits at multiple points in the season; expression can change with flow and stress.
- Compare results each year against honey and survival targets before selecting breeders.
- Document which traits co‑occur so selection avoids drifting toward unwanted behaviors.
| Trait | Benefit | Check |
|---|---|---|
| Hygienic | Lower disease and mites | Freeze‑killed brood removal |
| VSH | Fewer reproductive mites | Brood inspection for mite reproduction |
| Grooming | Damaged mites, lower drop | Sticky board mite damage |
Communicate tradeoffs with your team so selection and culling align with resistance and honey goals for the year.
Step‑by‑Step Implementation Timeline for the Present Season
Begin with simultaneous sampling across apiaries to set reliable baseline mite and behavior metrics. Early coordination makes comparisons valid across time and area. Use the same sheets, team, and testing window when possible.
Early season setup: baseline mite sampling and initial screening
Sample mite levels in each hive and run hygienic screens on strong colonies at the same time. Install a half frame of drone comb early; remove and freeze it per your IPM schedule to reduce varroa pressure.
Mark candidate colonies for queen rearing based on honey buildup, brood quality, and temperament. Exclude weak or diseased colonies from breeder pools.
Mid‑season queen rearing, requeening, and drone brood management
Start queen rearing and build mating nucs. Schedule requeening of poor performers so six weeks later their worker cohorts can be validly evaluated.
Establish drone source colonies from selected lines and position them to influence matings in the intended area during peak flights.
Late‑season evaluation: data roll‑up, overwintering prep, and breeder selection
Repeat hygienic and VSH assessments after nurse turnover, then compare results within each apiary. Consolidate data for every colony and queen into a year summary.
Prepare hives for winter with adequate honey and healthy queens. Cull queens that fail temperament or mite control thresholds and use findings to plan next year’s queen rearing, drone yard placement, and IPM timing.
Scale, Sustainability, and Continuous Improvement
Maintain program scale and clarity. Standardize inspection cadence, testing windows, and data entry so results compare across apiaries.
Keep genetic diversity wide. Select breeders from a sufficient number of colonies to avoid inbreeding and the risk of diploid drones and shot brood.
Consider bringing in approved germplasm and diverse stock through university partners or reputable breeders. Washington State University and other labs work to preserve Old World genes that help broaden U.S. honey bee diversity.
Integrating IPM and practical controls
Make IPM central. Combine scheduled monitoring, early‑spring drone brood trapping, and targeted interventions to cut chemical reliance.
Research, including LASI work, shows drone brood trapping lowers varroa pressure when paired with validated hygienic assays and mite counts.
Collaboration and continuous review
Work with local beekeepers, breeders, and labs to coordinate drone production and queen distribution that strengthen regional stock.
- Allocate resources where they matter: selection rigor, clean records, and disciplined culling.
- Run annual reviews that adjust thresholds and refine which genes and traits deliver the best resistance and honey outcomes.
- Share lessons and training materials on your website or with extension services to scale sustainable beekeeping across the region.
Conclusion
Close the loop on seasonal data by linking removal rates and mite counts to breeder selection. Name breeder queens and assign culls each year so colonies with strong hygienic behavior and low varroa mites lead your stock forward.
Use multiple measures — VSH scores, grooming checks, and freeze‑killed brood removal — and record cells uncapped, removal percentage, and mite number for each colony. Time tests after six weeks so worker bees reflect the current queen’s genetics.
Pair selection with practical control like early spring drone brood trapping on a half frame. For training and added guidance, see beekeeping courses and training. With clear records and steady selection, honey yields, colony health, and mating outcomes will improve season after season.
