What is a noticeable symptom of chalkbrood disease in a bee colony?

Chalkbrood disease is characterized by a specific symptom where the infected larvae appear mummified. This mummification occurs as a result of the infection caused by the fungus Ascosphaera apis, which invades the larvae, leading to their desiccation and hardening. The appearance of these larvae changes, making them look like small, pale, hard mummies, which is a distinctive indication of the disease's presence in a colony. Recognizing this symptom is crucial for beekeepers, as it aids in diagnosing health issues within the hive and addressing them promptly to manage the overall health of the colony effectively.

The other symptoms or choices do not accurately reflect the manifestations of chalkbrood disease. Brown stains could indicate other issues, such as staining from propolis or waste. A sac filled with a watery liquid is more associated with other conditions, such as certain types of brood diseases or normal larval development. Deformed wings in adult bees typically signify different issues, such as pesticides or genetic factors, rather than chalkbrood.
