Abstract

Pčelinja zajednica treba dostatne zalihe nektara, meda i peluda da bi zadovoljila
energetske i prehrambene potrebe. Pri tome potrebna je stalna dostupnost prirodne hrane, no u
rano proljeće i tijekom bespašnih razdoblja zbog loših vremenskih prilika, najpouzdaniji izvor
dodatne hrane je kvantitativno i kvalitativno zadovoljavajuće prihranjivanje pčelinjih zajednica
pogačama i / ili šećernim sirupom koje pčelar provodi u okviru dobre pčelarske prakse. Cilj
ovog rada bio utvrditi učinkovitost primjene proteinskih pogača tijekom prihrane pčelinjih
zajednica te utvrditi mogući utjecaj na stupanj invadiranosti sporama Nosema spp. Pretraženi
su uzorci odraslih pčela sakupljeni na pčelinjaku u pokusnim i kontrolnim skupinama (24) pod
hipotezom da će pčelinje zajednice bolje uzimati proteinske nego šećerne pogače, te da će se
smanjiti broj spora mikrosporidija Nosema spp. Laboratorijskim pretraživanjem uporabom
svjetlosnog mikroskopa utvrđena je prisutnost i kvantifikacija spora Nosema spp. Iako
analiziranjem rezultata nisu utvrđene statistički značajne razlike u broju spora između kontrolne
i pokusne skupine pčelinjih zajednica, tijekom trajanja pokusa uočeno je značajno smanjenje
broja spora Nosema spp. u pokusnoj skupini prihranjivanoj proteinskom pogačom uspoređujući
početak i tijek istraživanja.

Abstract (english)

A honeybee colony needs sufficient nectar, honey and pollen supplies to meet its energy
and nutritional needs. This requires constant availability of natural food, but in early spring and
during dearth periods due to bad weather conditions, the most reliable source of additional food
is quantitative and qualitatively satisfactory feeding of honeybee colonies with patties or sugar
syrup, which the beekeeper carries out within the framework of good beekeeping practice. This
study aimed to determine the impact of protein patties after application during additional
feeding of honeybee colonies and its possible impact on the degree of invasion with Nosema
spp. spores. Samples of adult bees collected in the apiary in experimental and control groups
(24) were examined under the hypothesis that honeybee colonies would take up protein patties
better than sugar patties, and that the number of spores of Nosema spp. microsporidia would be
reduced. Laboratory examination using a light microscope determined the presence and
quantification of Nosema spores spp. Although the analysis of the results did not reveal
statistically significant differences in the number of spores between the control and
experimental groups of honeybee colonies, a significant reduction in the number of Nosema
spp. spores were observed during the experiment in the colonies fed with protein patty,
comparing the beginning and course of the research.
