Povzetek

Ljudje že stoletja živimo s čebelami in uporabljamo njihove produkte. Zadnjih nekaj desetletij pa čebelarjem največjo težavo predstavljata, zatiranje parazitske pršice varoje (Varroa destructor) in pridobivanje čistih produktov, ki so brez ostankov kemičnih sredstev s katerimi to pršico zatiramo. Zaradi tega čebelarji vse bolj posegajo po naravnih sredstvih za zatiranje varoje, med katere spadajo tudi organske kisline. V raziskavi sem preučeval vpliv dodajanja organskih kislin (mravljinčna, ocetna in mlečna kislina) v panj na pridobivanje propolisa. Zanimalo me je, če bi bilo možno združiti proces zatiranja varoje in pridobivanja propolisa. Poskus sem izvedel tako, da sem v panj postavil 10 petrijevk v katere sem dodal omenjene kisline v različnih koncentracijah. Uporabil sem različna panjska sistema in sicer AŽ in nakladni panj. Zanimalo me je ali in kako kisline ter njihova koncentracija vplivajo na proizvodnjo propolisa v čebeljem panju. S poskusom sem ugotovil da različne kisline različno vplivajo na proizvodnjo propolisa. Vendar pa je bil prinos propolisa na petrijevke majhen in tako brez gospodarskega pomena. Opaziti ni bilo razlik pri količini propolisa v različnih panjskih sistemih. Moje ugotovitve so v skladu z drugimi avtorji, ki trdijo, da na proizvodnjo propolisa vpliva predvsem obdobje v letu, podnebje in lokacija panja ter da v obdobju paše čebele rajši kot surovine za propolis, nabirajo nektar in mano.

Sekundarni naslov:	Impact of adding organic acids in beehive on propolis production
Sekundarni povzetek:	For centuries we have been living with bees and using their products. In the last few decades, one of the biggest problems for beekeepers was the suppression of the Varroa mites (Varroa destructor) and the production of bee products, that don't contain residuals of chemicals, which are used for suppression of the Varoa mites.

In the last few decades, one of the biggest problems for beekeepers was the suppression of the Varroa mites (Varroa destructor) and the production of bee products, that don't contain residuals of chemicals, which are used for suppression of the Varoa mites. Therefore, more and more beekeepers use natural methods and substances, like organic acids. I studied the impact of adding organic acids in beehive on the production of propolis. The acids I used in my study were formic, lactic and acetic acid. I was interested if it was possible to combine the process of protecting bees against Varroa mites with production of propolis. In the experiment I used ten petri dishes in which I poured different concentrations of acids, mentioned above. In experiment, I used two different beehives, one was Langstroth beehive and the other was Slovenian AŽ hive. I wondered whether and how organic acids affect the production of propolis in beehive. During the experiment I observed, that the bees do respond differently to the presence of different organic acids, by applying propolis on the source of acid, although too small amounts to have production value. There were also no difference in quantity of propolis in different hive systems.
