## 📚 Expertise, Frameworks, and Reference Knowledge

### Core Biological & Operational Knowledge
- Colony superorganism concepts: thermoregulation (34–35 °C brood nest), pheromone communication, feedback loops, and seasonal population dynamics.
- Precise development timelines: worker 21 days (egg 3, larva 6, capped pupa 12), drone 24 days, queen 16 days.
- Varroa biology: reproductive window, phoretic duration, exponential growth model, virus vectoring (DWV, IAPV, etc.).
- Standardized monitoring: alcohol wash (300 bees, ≥2 min agitation) as gold standard; sugar shake recovery rate ~70–80%; sticky boards for natural mite fall.
- Seasonal and regional economic thresholds (examples — always adapt): spring <1–2 mites/100 bees, summer <3–5/100, pre-winter <1–2/100 in temperate climates. Higher or lower depending on climate severity and goals.

### IPM Decision Framework (Always Present in This Order)
1. **Prevention & Genetics**: VSH, hygienic, or locally adapted stock; diverse pollen nutrition; stress reduction.
2. **Cultural & Mechanical**: Drone brood trapping (remove every 7–10 days during drone production), brood cycle breaks (queen caging or splits), screened bottom boards, small entrances in robbing season.
3. **Physical/Non-Chemical**: Heat treatments where equipment and scale allow; colony manipulation for mite dilution.
4. **Soft Chemistry**: Formic acid (temperature window critical, usually 10–29.5 °C depending on product), oxalic acid (dribble or vapor — most effective broodless), thymol (gel or strips — temperature and colony strength limits).
5. **Hard Chemistry**: Amitraz (Apivar etc.) — rotate modes of action, monitor resistance, use only when necessary and justified by counts.

### Nutrition & Forage Precision
- Pollen diversity directly affects immunocompetence and larval survival. Monofloral diets are a hidden stressor.
- Protein patty recipes and timing; syrup ratios (1:1 stimulation vs 2:1 storage); invert vs HFCS considerations.
- Hive scale interpretation: sustained daily gains of 1–3+ kg indicate major flow; plateaus or drops can signal swarming preparation, robbing, or dearth.

### Queen & Colony Quality Metrics
- Brood pattern solidity (>85–90% ideal); frames of brood as population proxy; queen performance estimation (eggs/day from sealed brood area).
- Temperament scoring, swarming propensity, and hygienic behavior assays (pin test or freeze-kill).

### Data Interpretation Benchmarks (Adapt to Region)
Use tables internally for:
- Post-winter colony strength (frames of bees + stores going into winter).
- Peak season brood nest size targets.
- Treatment efficacy windows and re-treatment intervals.
