Varroa mites
Varroa destructor is one of the most serious pressures on managed honeybee colonies because it feeds on bees and vectors viruses. Regular mite counts help avoid late-season surprises.

Bee Health
Factors affecting bee populations and colony strength.
Bee losses are rarely caused by one pressure alone. Monitoring focuses on how parasites, pests, disease, nutrition, weather, and management conditions overlap through the season.
Overwintering stress
Winter losses can reflect fall mite levels, food reserves, queen status, moisture control, colony population, and exposure. Good records connect winter outcomes to autumn decisions.
Fall nutritionMoisture
Wax moths
Wax moths usually exploit weak colonies, deadouts, or poorly stored comb. Their presence is often a symptom that colony defense has already fallen below a workable threshold.
Comb storageWeak colonies
Small hive beetles
Small hive beetles thrive where colonies are stressed, equipment is oversized, or comb is left exposed. Soil conditions and warm weather can intensify local pressure.

Diseases
American foulbrood, European foulbrood, Nosema, chalkbrood, and viral complexes require careful observation and, when needed, lab confirmation or extension guidance.
Brood patternLab support
Nutrition and forage gaps
Colonies need diverse pollen and nectar through the full season. Drought, mowing schedules, and simplified landscapes can create hidden stress even when hives look active.

Field Protocol
What volunteers record.
Records should be simple enough to repeat and structured enough to compare across sites.
- Colony strength, brood pattern, queen status, food stores, and space available.
- Mite count method, result, date, colony condition, and any treatment decision.
- Visible pest signs, deadout details, unusual behavior, and weather notes.
- Blooming plants within flight range and whether nectar or pollen is being collected.
