As the fat body is crucial for many bodily functions such as hormone and energy regulation, immunity, and pesticide detoxification, the bee is left in a severely weakened state.
Sometimes, the incorrect names varroatosis or varroasis are used. “They’re like something out of a monster cartoon with this huge yellow-orange face,” Susan Cobey, a bee breeder with Washington State University’s Department of Entomology, recently told WSU Insider of the invasive species.

However, the most effective long-term way of protecting bees against V. destructor is by breeding bees that are resistant to these mites.[4]. The screened bottom board is also being credited with increased circulation of air, which reduces condensation in a hive during the winter. Varroa mites can be treated with commercially available acaricides. Varroa mites are flat, having a button shape. In Puerto Rico it was noted that compared to European species, the Africanised bees groomed for longer periods - often more effectively - biting and damaging Varroa mites..
