Varroa Mites

Varroa is a genus of parasitic mesostigmatan mites associated with honey bees, originally placed into its own family, Varroidae, but later revised as a subfamily. The genus was named for Marcus Terentius Varro, a Roman scholar and beekeeper. The condition of a honeybee colony being infested with Varroa mites is called varroosis (also, incorrectly, varroatosis).

Varroa mites, but especially the species Varroa destructor, are recognised as the biggest pest to honeybees worldwide due to their ability to transmit diseases such as deformed wing virus (or DWV) to larval or pupating bees, resulting in death or severe deformity of the pupae.
