In the present investigation, comparative study was carried out between Carniolan, Italian races and F1 Italian hybrid in collecting propolis. Propolis was gathered by: using wooden traps, between frames, from feeders. Wooden traps provided with holes, 1.5 cm in length and 3 mm in width, were put on the top bars of the frames. Results explained that Carniolan race was obviously outstanding in gathering activity of propolis by the three different methods during the whole year. Therefore, the total colony production was (46 gm/colony/year) in Carniolan race from the feeders. In contrast, 1. t Italian hybrid was the lowest, producing (33 gm/colony/ year). And, Italian race produced (34 gm/colony/year) from the feeders. Regarding traps, Italian race was superior, producing (22.3 gm/colony/year). While, 1. t Italian hybrid was the lowest, producing (13 gm/colony/year). Regarding between frames, both of Italian and 1. t Italian hybrid produced nearly the same amounts with an average 8.2, 8.3 gm /colony/year, respectively. While, Carniolan race produced 10.9 gm/colony/year.
