Fuente: WIPO "varroa" A system, method, and apparatus for thermal management of Varroa mite infestations in manmade beehives includes a portable direct current controller that selectively controls power to a heated bottom board that is installed underneath the bottommost brood box of the beehive. The bottom board elevates the temperature within the brood boxes to a constant temperature of approximately 107° F. The bottom board provides an entrance that is movable between a closed condition and an open condition. An adjustable queen excluder is disposed between the uppermost brood box and the honey super box, wherein the queen excluder is moveable between a passage position and an exclusion position preventing passage of the entire honeybee colony between the brood boxes and the honey super boxes. The excluded position prevents leakage of the heat as well as keeps the honey super boxes below the elevated temperature.
