This document concerns a method of thermal treatment of bee coloniesin order to ensure the eradication of bee parasites in the interior of a hiveframesuperstructure, through the transformation of short wave electromagneticradiation tolong wave thermal radiation, where the essence of the invention is that anefficienttemperature increase above the value of 40°C is achieved by the help ofsecondarythermal energy and/or primary thermal energy when sunrays or generatedradiationpermeate through a thermosolar lid onto the active surface of a photo-absorbentcomponent and/or go through a transparent screen into the interior of the hiveframesuperstructure, where they land on the active photo-absorbent layer of athermo solarframe. Another fundamental element of the invention is the construction of adevicefor the thermal treatment of bee colonies where the hive frame superstructureisutilized for the formation of primary thermal energy or secondary thermalenergy, orfor the simultaneous formation of primary thermal energy and secondary thermalenergy, either equipped with the thermosolar lid constructed with a photo-absorbentcomponent which contains an active surface and a radiant surface, or is fittedon theside with a transparent screen, while in the interior of the hive framesuperstructure athermo solar frame is placed which is constructed with an active photo-absorbentlayer situated in a direction facing the screen, or the hive framesuperstructure isequipped both with a thermosolar lid constructed with a photo-absorbentcomponentwhich contains an active surface and a radiant surface, and also with atransparentscreen situated on the side, while in the interior of the hive framesuperstructure athermo solar frame is placed, which is constructed with an active photo-absorbentlayer situated in a direction facing the screen.
