Honey bees are not especially prone to bee diseases but there are things from which they can suffer. Some of these can be treated, some not.
Follow the links below to get an idea of how to identify some honeybee disease and treat them where possible.
Colony Collapse Disorder technically this is not a disease. Bees disappear from the hive. Hives are opened in the spring to find stored honey left but no bees disease or alive.
Nosema is one of the more widespread afflictions. Adult worker bees have difficulty flying and have a tendency to crawl. Yellow streaks of diarrhea can be see on the front of the hive.
Chalkbrood is a very common fungal disease. Discarded bodies are seen at the entrance particularly in spring. The dead bodies hard and often, but not always, chalky white.
Chilled brood is indicated when a discarded bodies are seen at the entrance but with chilled brood they are soft and translucent rather than moldy and white.
American Foulbrood (AFB) is a bacterial infection which is highly contagious in bees. Brood dies after it has been capped. The colour darkens and the caps often seem sunken, wet and greasy. You’ll smell a foul smell, something like old-fashioned hoof and horn glue.
European Foulbrood (EFB) is also a bacterial bee disease. Unlike American Foulbrood, larvae die before it’s capped. They often have a melted appearance. The hive will smell, but not as bad as with AFB.
Sacbrood is caused by a virus. Infected larvae turn yellow and eventually dark brown. They look as though they are contained in a water-filled sack.
Stonebrood is a fungal disease. It causes larvae and pupae to turn hard and solid, mummified. Brood may be covered with a powdery green fungus.
A Varroa Mite infestation will lead to the death of a honey bee colony, usually in the late autumn through early spring. The Varroa mite is the parasite with the most pronounced economic impact on the beekeeping industry. It may be a contributing factor to Colony Collapse Disorder (CCD).
