M L Gornich (Kyiv), in his report titled "Petro Prokopovich and World Beekeeping", indicated that papers of Prokopovich were translated into German and French in his time and were well known in Europe. He suggested that some experts consider that the movable frame bee hive of Johann Dzierzon was also constructed on the basis of Prokopovich's invention."
