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.
Collecting mites from the bottom board of a bee colony Counting damaged mites is a method to measure the trait of mite-biting behavior in honey bee colonies. Procedures for mite counts included 1) collecting mites, 2) placing mites on microscope slides, 3) counting the number of mites, 4) observing mites for any damage under a microscope, and 5 ...
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.
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).
THYMOVAR is a product to control the Varroa mite (Varroa destructor) on bees (Apis mellifera) and contains the essential oil thymol. THYMOVAR contains thymol, a volatile substance which sublimates in the air depending on temperature. On release, thymol vapour concentrations build up in the treated beehive.
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 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 these mites. [85] Varroa destructor is a parasitic mite that colonizes beehives and preys on honey bees by consuming their ...
