Varroa destructor, the Varroa mite, is an external parasitic mite that attacks and feeds on honey bees and is one of the most damaging honey bee pests in the world. [ 2 ] [ 3 ] A significant mite infestation leads to the death of a honey bee colony, usually in the late autumn through early spring.
Varroa is a genus of parasitic mesostigmatan mites associated with honey bees, placed in its own family, Varroidae. [4] 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 destructor and V. jacobsoni are parasitic mites that feed on the fat bodies of adult, pupal and larval bees. When the hive is very heavily infested, Varroa mites can be seen with the naked eye as a small red or brown spot on the bee's thorax. Varroa mites are carriers for many viruses that are damaging to bees.
Varroa destructor (Varroidae) is a major pest of honey bees. It harms bees both directly by feeding on fat body tissue, and indirectly by transmitting viruses. [8] Similarly, the red mite (Dermanyssus gallinae) feeds on the blood of birds, including poultry (chickens, turkeys, ducks) and wild birds. It reduces animal health, welfare and production.
Mites which colonize human skin are the cause of several types of itchy skin rashes, such as gamasoidosis, [51] rodent mite dermatitis, [52] grain itch, [53] grocer's itch, [53] and scabies; Sarcoptes scabiei is a parasitic mite responsible for scabies, which is one of the three most common skin disorders in children. [54]
About 27% of hives did not survive the winter, and the Varroa mite was identified as the cause in 85% of the cases. [84] Varroa mites also affect the queen's ability to reproduce, which is detrimental to the survival of the hive. [43] As such, Varroa mites have been considered as a possible cause of CCD, though not all dying colonies contain ...
They are primarily transmitted by direct human to human contact. But they can be transmitted without touching another human if scabies are on blankets, towels, sheets, and other personal items.
Varroa jacobsoni is a species of mite that parasitises Apis cerana (Asian honey bees). The more damaging Varroa destructor was previously included under the name V. jacobsoni , but the two species can be separated on the basis of the DNA sequence of the cytochrome oxidase I gene in the mitochondrial DNA .
