Symptoms
- CHALKY-WHITE COVERING ON LARVAE.
- GRAY OR BLACK FUNGUS ON LATER-STAGE INFECTION.
- MUMMIFIED LARVAE.
- MAINTAIN CONTROLLED, SANITARY BEE HUSBANDRY.
- KEEP HIVES WARM AND DRY (OR TEMPERATURECONTROLLED IN EXTREME CASES)
- LOOK FOR HARDENED/MUMMIFIED LARVAE AT HIVE ENTRANCE.
- VERIFY CHALKY WHITE/GRAY/BLACK GROWTH ON BROOD.
What is bee dysentery?
In humans, dysentery is a contagious illness caused by bacteria that are associated with unsanitary conditions. But in honey bees, dysentery is not caused by a pathogen. Instead, it is the result of an excess amount of fecal matter in the honey bee’s gut. It’s not a disease, but simply a condition.
