sacbrood
insect disease
Quick Summary
Sacbrood is a virus disease that affects honeybee larvae. Infected larvae shrivel and become scalelike. While superficially similar to foulbrood diseases, sacbrood is seldom serious and can appear and disappear spontaneously. No chemical control is typically needed, and beekeepers may requeen the colony if the problem persists. Sacbrood is one of several diseases that can affect honeybees, alongside bacterial infections like American and European foulbrood, fungal diseases such as chalk brood, and parasitic mites.12
