Introduction Varroa destructor (Anderson and Truman) previously described as Varroa jacobsoni (Oud) is a parasitic mite of adult bees and brood. In the past hundred years or so it has become the most serious pest of Western honeybees across the globe, particularly for the European honey bee Apis mellifera which lacks natural defences to be able to deal with the mite by themselves. The genus Varroa includes in excess of 18 genetically different strains of mites (Cobey, 2001). Varroa destructor and Varroa jacobsoni (Acari: Varroidae) are thought to be closely related (Zhang, 2000; Delaplane, 2001), both parasitizing the Asian honey bee, Apis cerana.However, V. jacobsoni, originally described by Oudemans in 1904, is not the same species as that which also attacks Apis The varroa mite is an insidious pest that poses a significant biosecurity threat to the common European honeybees whose pollination services add an estimated $14.2 billion to the Australian agricultural and horticultural industries each year. This episode of Turf’n’Surf, 2020-01-17 Varroa Mites become a problem when the population jumps to dangerous levels, usually around August. Check mites several times a year and treat when populations increase to keep the mite population under control.

The honeybee, a major pollinator crucial for our ecosystems, agriculture and economy, is threatened by the parasitic mite Varroa destructor. David's work has shown that the presence of Varroa mite leads to selection for a particular strain of DWV which causes colony decline. Work is currently underway  queen rearing equipment, beekeeping tools, tracheal mite controls and varroa mite controls, as well as honey extraction equipment and honey bottling supplies.

Identifying varroa mites – Method 1 . The easiest way to estimate the mite load in a colony is to fork drone pupae. I count 10 visible mites.

Varroa mites can reproduce on both worker and drone brood in Apis mellifera, but reproduce exclusively on drone brood in A. cerana, its original host. Many factors, such as grooming behavior (removing mites during phoretic stage from adults), hygienic behavior (removing mites from pupae during reproductive stage), duration of brood state, and

During winter months one Varroa mite can damage or even kill up to 8-10 bees inside the colony. If your colony is infected for more than 3% of mite it means that every third bee in your colony will die over the winter. Practically, your full colony will not survive.
