How does chalkbrood affect honey bee colonies?

Chalkbrood is a fungal disease, primarily caused by the fungus Ascosphaera apis, that specifically targets honey bee larvae. When the larvae become infected, they develop a chalky, mummified appearance, hence the name "chalkbrood." This disease impacts the colony primarily by reducing the number of viable worker bees that emerge from infected larvae, which can lead to decreased population growth and overall colony strength.

By affecting the brood, chalkbrood has the potential to compromise vital functions within the colony, such as foraging, hive maintenance, and ultimately honey production. Additionally, while other options mention effects on adult bees, honey contamination, or aggression, chalkbrood's direct and significant impact lies solely in its destructive effects on the developing larvae. Therefore, understanding this disease's mechanism is crucial for beekeepers in managing and maintaining healthy colonies.
