These mites are tiny, the size of a pinhead, and they are a parasite of honey bees. Varroa mite numbers build up over time, eventually killing honey bee nests and hives if chemical mite killers or other management strategies are not applied. These mites inflict physical injury on their honey bee hosts from feeding on host hemolymph and fat body cells/cellular components, and serve as the vector for deadly honey bee viruses, including Deformed wing virus (DWV) and the related Varroa destructor virus-1 (VDV-1) (i.e., DWV-like viruses). Varroa mite infestation represents one of the greatest threats to honey bee health, honey production, and pollination services. When honey bee colonies are untreated or treated ineffectively, colonies can fail and beekeepers can incur major economic losses, and, ultimately, agricultural food production may be impacted. Se hela listan på beekeepclub.com Varroa mites have “fecal sites” on the cell, where they deposit their feces, which are white due to a high concentration (~95%) of guanine.

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 The ectoparasitic mite Varroa destructor is one of the most destructive pests of the honey bee (Apis mellifera) and the primary biotic cause of colony collapse in many regions of the world.
