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.
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 sensitive hygiene (VSH) is a behavioral trait of honey bees (Apis mellifera) in which bees detect and remove bee pupae that are infested by the parasitic mite Varroa destructor. V. destructor is considered to be the most dangerous pest problem for honey bees worldwide. VSH activity results in significant resistance to the mites.
Varroa destructor is a parasitic mite that colonizes beehives and preys on honey bees by consuming their hemolymph. Varroa mites parasitize all types of honey bees (workers, nurse bees, larvae) depending on their life cycle stage. During the phoretic stage, Varroa prefer to attach to nurse bees as this results in higher fitness leading into the ...
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.
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.
In conjunction with the staff at the Baton Rouge Bee Laboratory, the Russian Honey Bee Breeders Association (RHBA) was conceived in the late 1990s, and works to certify apiarists who maintain only pure-bred Russian honey bees. These stocks are bred and DNA tested for resistance to Varroa mites and increased honey production. Their charge is as ...
