Abstract

Pčelari skupljaju pelud pomoću skupljača peludi. Međutim, ovisno o načinu skupljanja, smanjen unos peludi može izravno utjecati na vitalnost pčelinje zajednice. Stoga je cilj rada bio utvrditi učinak načina skupljanja pčelinje peludi na njezinu masu i razvoj pčelinje zajednice. Istraživanje je bilo provedeno na devet pčelinjih zajednica sive pčele podijeljenih u tri skupine po tri zajednice. U prvoj skupini su na košnice postavljeni vanjski skupljači, u drugoj unutarnji, dok je treća skupina bila kontrolna. Na svakoj zajednici pratila se jakost te površina legla, peludi i meda „Liebefeld“ metodom. U vanjskim je skupljačima bilo prosječno utvrđeno 70,77 g, a u unutarnjim 101,37 g pčelinje peludi. Također je utvrđeno da se broj pčela, kao ni na broj stanica s medom niti peludi nije statistički značajno razlikovao s obzirom na tip skupljača. Međutim, značajno manji broj stanica legla je utvrđen u zajednicama s unutarnjim (28 500) u odnosu na zajednice s vanjskim skupljačem (37 153).

Abstract (english)

Beekeepers can collect bee pollen with pollen traps. However, depending on a collecting method, smaller intake of bee pollen can directly affect colony’s vitality. Therefore, the aim of this paper was to determine the effect of different pollen traps on the mass of collected bee pollen and on the development of honey bee colony. The research was conducted on nine colonies of carniolan honey bee divided into three groups of three hives. First group had front mounted traps, second had bottom traps, and third group was control group. Colony strength and number of cells containing brood, pollen and honey was monitored in four occasions with “Liebefeld” method. Front mounted traps had on average 70,77 g, and bottom traps had 101,37 g of bee pollen. The number of bees, as number of cells containing honey and pollen, was not significantly different considering the type of pollen trap. However, significantly lower number of brood cells was found in colonies with bottom traps (28 500), than in colonies with front mounted traps (37 153).
