Score colony-level AFB infection risk based on spore load exposure, hive age, hygienic behavior index, and regional outbreak pressure. Outputs a 0–100 risk score with intervention threshold guidance.
10 = highly hygienic queen; 0 = no hygienic behavior
0 = all new equipment; 10 = extensive used comb/equipment

💉 Honey Bee Vaccine Efficacy Model
Model the biological efficacy of the Dalan AFB vaccine based on queen age, colony size, brood coverage, and vaccination timing. Outputs predicted protection rate and colony-level immunity index.
Younger queens produce more vaccinated offspring
Percentage of available brood frames occupied
Peak immunity develops 3–6 weeks post-vaccination

🐝 Colony Survival Probability
Calculate the probability of colony survival through the active season based on disease exposure, vaccination status, Varroa load, winter cluster strength, and management intensity.
Treatment threshold: >2 mites/100 bees
10 = peak strength; 1 = failing colony

Dalan Animal Health is a pioneering animal health biotech developing vaccines across multiple species — including the world's first conditionally approved USDA vaccine for honey bees against American Foulbrood (Paenibacillus larvae), as well as vaccine programs for shrimp and other aquatic and invertebrate species. AgrStak's SF29 platform is built in alignment with Dalan's honey bee vaccine research to translate vaccine science into apiary-level decisions.
