These sources describe chalkbrood, a fungal infection that targets honeybee larvae and transforms them into distinctive, chalk-like mummies. Beekeepers can identify the disease by observing these hardened remains at the hive entrance or noticing perforated brood cappings and a lack of colony growth. While the condition is often triggered by damp, cool conditions and may resolve as weather improves, management strategies include enhancing hive ventilation, reducing moisture, and providing nutritional supplements. If the infection persists, the materials suggest requeening the colony with a more hygienic genetic strain to encourage the removal of diseased larvae. Experts also recommend replacing old combs to eliminate fungal reservoirs and ensuring the hive is strong enough to defend itself against further decline.
