Beekeepers use several methods for monitoring levels of Varroa mites in a colony. [34] They involve either estimating the total number of mites in a hive by using a sticky board under a screen bottom board to capture mites falling from the hive or estimating the number of mites per bee with powdered sugar or an ethanol wash. [35]
A white plastic sheet is sometimes coated with a slightly sticky substance, and slid over the bottom board to trap and count fallen varroa mites, a bee parasite that can infest hives. The entrance reducer is a square bar of wood to help the bees manage air circulation.
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.
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 ...
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 (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 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 ...
