Fall Dwindling Disease, Disappearing Disease, Fall Colony Collapse
Causative Agent: Unknown
Range: North America, possibly Europe
Life cycle/ Symptoms:
- Unknown, hives that are weak in the Fall seam to be at higher risk
- Apparently normal hives will disappear with in 1-2 weeks and few dead will be found in or around the hive. Occasionally the queen and a small number of workers will be found alive but encapsulated in the hive.
- If you suspect one or more of your hives are experiencing CCD it is recommended that you :
Do not combine a weak colony with a strong one
If a colony fails and you suspect CCD place the hive and frames in a place where other colonies cannot raid it
Use Fumagillan in your sugar water if feeding
If you suspect CCD in a failing colony use Terramycin to treat for European Foulbrood
If mites become a problem use soft chemicals, such as Apiguard, Apilife VAR, or MiteAway II to suppress populations.
