20.500.12556/RUL-169478 Izvedba in ugotavljanje uspešnosti prašenja matic kranjske čebele z uporabo zamikanja paritvenih letov matic in trotov Performance and determination of the success of queen mating (Apis mellifera carnica) using the delayed flight time method V diplomskem delu smo ugotavljali uspešnost parjenja matic z uporabo metode zamikanja paritvenih letov matic in trotov. Poskus smo izvajali na Ljubljanskem barju v dveh ponovitvah in sicer v juniju in juliju. Tako v prvi kot v drugi ponovitvi smo v poskus vključili 30 čebeljih družin, naseljenih v prilagojenih panjih – plemenilnikih. V prvi ponovitvi smo spremljali izlete in prilete matic, brez dodanih časovno manipuliranih trotarjev na vzrejališču. V drugi ponovitvi pa smo na vzrejališče dodali časovno manipulirane trotarje in znova beležili izlete in prilete matic. Matice smo spuščali na parjenje v dveh terminih in sicer ob 17.17 uri in ob 18.17 uri. V kontrolni skupini nismo postavljali časovnih omejitev. Po analizi rezultatov smo ugotovili, da so se vse matice iz testnih skupin kljub zamaknjenim paritvenim letom uspešno sparile. V obeh ponovitvah se je največje število letov pojavilo prvi dan opazovanja, najmanjše pa zadnji, peti opazovani dan. Čas trajanja izleta je bil, v obeh ponovitvah, najdaljši v primeru vrnitve matice z vidnimi svatbenimi znaki. V nadaljevanju predlagamo obsežnejšo raziskavo, v kateri bi se spremljalo večje število matic in tudi lastnosti matic, ki bi bile uporabljene v testnih skupinah. In this work, the mating performance of queens was determined using the delayed mating flight method for both queens and drones. The experiment was carried out in two replicates in an area near central Slovenia called Brezovica. The replicates took place in June and July. In both the first and second replicates, 30 bee colonies were included in the experiment, which were housed in specially adapted mating hives. In the first replicate, we observed the departure and arrival of queens without the addition of time-manipulated drones in the area. In the second replicate, three colonies with timed drones were added and the departure and arrival of queens were again recorded. The queens were released for mating at two specific times: 5:17 pm and 6:17 pm. In the control group, no time limits were set for the mating flights. After analyzing the results, we found that all queens in the experimental groups were successfully mated despite the delayed mating flights. In both replicates, the highest number of flights was recorded on the first day of observation, while the lowest number was recorded on the fifth and last day of observation. Furthermore, the duration of the mating trip was longest in both replicates when the queen returned with visible nuptial signs. We suggest conducting a larger study with a larger number of queens and investigating the characteristics of the queens used in the test groups. čebelarstvo čebele kranjska sivka Apis mellifera carnica nadzorovano parjenje vzreja matic beekeeping honeybees Carniolan honeybee Apis mellifera carnica controlled mating queen rearing true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2025-05-30 07:16:13 2025-05-30 07:16:19 2025-05-31 04:25:58 0000-00-00 00:00:00 2025 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 257393 237768707 48064.pdf 48064.pdf 1 39889B7BD85B7A50DAA7B79B79F8F3A3 944a3fdfb10395bcfc68d423245263160c261f9f992f78f1367d4c45140022ae ea99d213-3d13-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=210889 Biotehniška fakulteta 0 0 0
