Another fundamental element of the invention is the construction of a device for the thermal treatment of bee colonies where the hive frame superstructure is utilized for the formation of primary thermal energy or secondary thermal energy, or for the simultaneous formation of primary thermal energy and secondary thermal energy, either equipped with the thermosolar lid constructed with a photo-absorbent component which contains an active surface and a radiant surface, or is fitted on the side with a transparent screen, while in the interior of the hive frame superstructure a thermo solar frame is placed which is constructed with an active photo-absorbent layer situated in a direction facing the screen, or the hive frame superstructure is equipped both with a thermosolar lid constructed with a photo-absorbent component which contains an active surface and a radiant surface, and also with a transparent screen situated on the side, while in the interior of the hive frame superstructure a thermo solar frame is placed, which is constructed with an active photo-absorbent layer situated in a direction facing the screen.
