🩺 Differential Diagnosis of Bee Brood Diseases

A systematic guide to distinguishing American foulbrood, European foulbrood, chalkbrood and sacbrood by the specific tests and features that separate them.

Entomology & Insect Behaviour3DAdvanced60 FPS

A 3D section of honeycomb where each brood cell can show the specific signs of American foulbrood, European foulbrood, chalkbrood or sacbrood, plus a simulated matchstick "ropiness" test — the classic field diagnostic that separates AFB from its look-alikes.

🔬 What It Demonstrates

Each disease is rendered with its distinguishing capping, larval colour and posture: AFB's sunken perforated cappings and ropey collapse, EFB's uncapped twisted larvae, chalkbrood's loose chalky mummies, and sacbrood's fluid-filled gondola-shaped larva.

🎮 How to Use

Pick a suspected disease and severity, toggle cappings on or off, then click any diseased cell to read its diagnostic notes — or run the stretch test to see whether the sample is ropey (AFB) or not (everything else).

💡 Did You Know?

AFB spores can survive in comb, hive tools and honey for over 40 years, which is why a positive ropiness test usually leads to burning the hive rather than attempting treatment.
