Viruses are pieces of genetic material that parasitize a host cell, making the cell produce more viruses. No vaccines or medications are available for any of the honey bee viruses. Therefore, good sanitation practices are the key to prevention. Comb replacement and requeening are the best practical responses to a virus infection.

Black queen cell virus is associated with Nosema disease and causes the death of queen larvae or prepupae after their cells are sealed. The larva will then turn black along with the walls of the cell. Treating colonies with Fumidil-B® to control Nosema may help keep this disease at bay.
