Line 1: Line 1:
The Varroa mite, ''Varroa destructor'', is an external parasite that lives on honey bees (both ''Apis mellifera'' and ''Apis cerana''). The adult mites feed on the hemolymph of adult honey bees and lay their eggs in brood cells in the honey bee hive. This parasite is one of the main threats to honey bee hive health and is thought to play a role in [[colony collapse disorder]]. The concurrent transmission of viruses, such as deformed wing virus, causes the main mortality in the honey bees.
'''Early summer'''<br />
This is the time when you should begin to remove the sealed drone brood that have an increased number of Varroa mites. You can diminish the mite population considerably by continuously growing drone brood and removing them regularly. The drones are usually reared until mid-July, after which the drone removal can be stopped.
'''Mid Summer'''<br />
You can continue removing drone brood for as long as the colony is willing to grow them. The swarms and nucleus can be treated for Varroa with treatments like evaporating thymol or trickling oxalic acid in as early as midsummer if no honey is harvested from these colonies during the same season.
'''Late summer'''<br />
The winter bees develop during August and September and Varroa mites might injure the developing bees. It is for this reason that the Varroa control in August is essential. The details of the techniques and protocols for Varroa treatment vary slightly between the Nordic countries, but the basic principles are the same in beekeeping regardless of bees or area.
'''Fall'''<br />
Nordic brown bees have a shorter brood rearing period compared to other subspecies. Brood rearing begins later in the spring and stops earlier in the fall. The broodless period also begins earlier in the fall and gives a good chance for Varroa control on adult bees.
