Fecha de publicación: 15/05/2014 Fuente: WIPO "hive" A thermal treatment of bee colonies to ensure death of bee parasites in an interior of a hive frame superstructure through transformation of short wave electromagnetic radiation to long wave thermal radiation, where an efficient temperature increase above the value of 40° C. is done by the help of a secondary thermal energy and/or a primary thermal energy when sunrays or a generated radiation permeate through a thermosolar lid on an active surface of a photo-absorbent component and/or go through a transparent screen into the interior of the hive frame superstructure and land on an active photo-absorbent layer of a thermo solar frame. Also described is construction of a device for pursuance of a thermal treatment of bee colonies. Other implementations are also described.
