Abstract

Na području Zabiokovlja uz nektarnu pašu učestalo se pojavljuju i medna rosa na maklenu, koju ne izlučuju lisne ili štitaste uši, već cvrčak (Acericerus heydenii). Kako se radi o pašnom potencijalu koji nije dovoljno istražen, cilj je ovog rada bio utvrditi skupljačku aktivnost pčelinje zajednice. Istraživanje je bilo provedeno na tri pčelinje zajednice sive pčele, gdje je praćena skupljačka aktivnost i provedena analiza sadržaja mednog mjehura i peludnog tereta. U 8:00 je bila utvrđena značajno veća masa sadržaja mednog mjehura (18,58 mg) u odnosu na uzorke prikupljene u 18:00 (11,93 mg) i one prikupljene u 13:00 (11,45 mg). Analizirajući masu peludnog tereta u 18:00 sati je utvrđena značajno niža masa peludnog tereta (7,83 mg) u odnosu na uzorke prikupljene u 8:00 (10,88 mg) i 13:00 (9,82 mg). Analizom sadržaja mednih mjehura, u najvećem je udjelu (62, 21%) utvrđena medna rosa, što u kazuje na prisutnost cvrčka (A. heydenii) na istraživanom području.

Abstract (english)

In the Zabiokovlje area, along with nectar abundant pastures, honey dew deposits, which were not the result of aphid nor scale lice excretions, rather cicada (Acericerus heydenii), appear on Montpellier maples (Acer mospessulanum). Since the pasture potential in the area was not fully researched, the goal of this study was to determine foraging activity of honey bee colonies. Reasearch was executed on three carniolan honey bee colonies on which foraging activity was observed and honey sac content and pollen load mass was analyzed. It was determined that there was a significant increase in the content of the honey sacs at 8:00 (18.58 mg) as compared to samples taken at 18:00 (11.93 mg) and 13:00 (11.45 mg). Analyzing the mass of pollen loads it was determined that samples from 18:00 (7.83 mg) had significantly less mass than samples collected at 8:00 (10.88 mg) and 13:00 (9.82 mg). Analyzing the honey sac content, it was determined that the bulk (62,21%) was honey dew, which indicated the presence of cicadas (A. heydenii) in the reasearch area.
