Chalkbrood Recommendations

chalkbrood mummies

A pathogenic fungus called chalkbrood can turn infected larval honey bees into “mummies,” killing them and reducing their colony’s population and productivity. Florida’s subtropical climate may contribute to a greater incidence of the disease, which is common throughout the state. This 2-page fact sheet describing chalkbrood and listing some management strategies to control it was written by Malcolm T. Sanford, Cameron J. Jack, and Jamie Ellis, and published by the UF Department of Entomology and Nematology, December 2016.
