chalk brood
insect disease
Quick Summary
Chalk brood is a fungal disease that affects developing honeybee larvae. The fungus, Ascosphaera apis, causes the larvae to become covered in a white, woolly growth. These larvae then harden into chalky white to grayish-black masses, which is fatal to them. This disease is one of several that can impact honeybee colonies, alongside other brood diseases like American foulbrood and European foulbrood, as well as diseases affecting adult bees such as Nosema disease.12
