Beekeepers face various challenges in maintaining healthy hives. This comprehensive symptom checker aims to assist Australian beekeepers in identifying key symptoms associated with common bee diseases and pests, including Varroa mites, European foulbrood, Chalk brood, Sacbrood virus, and American foulbrood.

Symptoms Checklist:




European Foulbrood

Chalk Brood

Sacbrood Virus

American Foulbrood

Distorted wing shapes and sizes in adult bees.


Darkened Brood Cells

Brood cells appear darker due to the presence of mites.


Chewed or Pierced Brood Caps

Irregular openings in capped brood cells caused by mite activity.


Abnormal Pupae

Deformed or discolored pupae in the capped cells.

Foul Odor

Unpleasant odor emanating from the affected brood.




Irregular Cell Capping

Abnormalities in cell capping observed during inspection.






Key Disease Differentiators:

  • Varroa Mites:
    • Notable for deformed wings and darkened brood cells.
    • The presence of chewed or pierced brood caps and abnormal pupae.
  • European Foulbrood:
    • Recognized by ropey larvae and sunken or discolored caps.
    • Foul odor and irregular cell capping are common signs.
  • Chalk Brood:
    • Characterized by irregular cell capping and a foul odor.
  • Sacbrood Virus:
    • Infected broods may exhibit reduced longevity and irregular cell capping.
  • American Foulbrood:
    • Recognized by a foul odor and irregular cell capping.

Preventive Measures and Control:

  • Integrated Pest Management (IPM): Implement IPM strategies for comprehensive disease and pest control.
  • Regular Hive Inspections: Conduct regular inspections to monitor symptoms and detect issues early.


A thorough understanding of these symptoms empowers beekeepers to differentiate between various bee diseases and pests, facilitating timely intervention and promoting overall hive health. Regular training and collaboration with local beekeeping experts enhance the effectiveness of disease management strategies.

Note: This checklist serves as a guide and should be complemented with hands-on training and consultation with local beekeeping experts.
