Zaletavanje čebeljih trotov med različnimi panji in ugotavljanje njihovega porekla : diplomsko delo : visokošolski strokovni študij = Drifting of honeybee drone between different hives and establishing of their origin : graduation thesis : higher professional studiesPorenta, MatejaČebelja družina vzredi preko leta tisoč trotov. Matica se običajno v dveh paritvenih izletih plemeni z 12 do 20 troti. Troti so pomembni za selekcijo, saj prenašajo dedne lastnosti na potomce. ... Splošno znano je, da trot ni preveč izbirčen, kam se bo zatekel po vrnitvi z izleta, to pa otežuje zanesljivost ugotavljanja njihovega izbora pri umetnem osemenjevanju matic. Da bi lahko ugotovili njihovo stopnjo zaletavanja, smo v poletnih mesescih leta 2003 izvedli poskus. Zrelo trotovsko zalego smo vložili v inkubator. En dan stare trote smo označili z barvnim flomastrom oz. z oštevilčenimi opalitnimi pločšicami. 1260 označenih trotov smo vložili v točno določene panje in jih nato pregledali v nekajdnevnih presledkih. Zbrane podatke smo statistično obdelali. Kot so pokazali naši rezultati, se troti očitno zaletavajo znatno manj, kot smo pričakovali. Troti so se zaleteli zelo mladi, pri starosti 2 do 3 dni, najverjetneje pri njihovem prvem orientacijskem poletu. V našem poskususta se dvakrat preselila le dva trota in veljata za veliko izjemo. Najopaznejši upad trotov smo zasledili tik po vložitvi. Spolno zrelost je v opazovalnem panju doseglo le 27 % trotov. Rezultate naše raziskave lahko uporabimo pri načrtovanju rejskih okrožij.Type of material - undergraduate thesisPublication and manufacture - Ljubljana : [M.
