Abstract

We evaluated the efficacy of supplementation with protein, yeast, or sugar candies of young honeybee colonies origi- nated from artificial swarms, by measuring strength and determining Nosema spp. spore level in adult bees in summer period. At the same time, we aimed to assess longevity of adult worker bees after feeding the same type of candies in controlled laboratory condition. The highest survival was found in Yeast and Protein candy group. On the contrary, the field study showed that artificial swarms produced significantly more pupae (2510.4 cm 2 , p=0.0001) in the 1 st period of measurement, and more larvae (964.8 cm 2 , p=0.003) and frames with bees (5.6, p=0.008) in the 2 nd period by feeding non-protein candy. In the 3rd period of evaluation of young colonies, the Sugar candy group had the highest number of frames covered by adult bees and honey stores, respectively (5.6, p=0.0009; 3432.0 cm 2, p=0.015). Sugar candy group produced the largest area of wax cells, however, the differences were not statistically significant. Nosema spp. spore level was checked quantitatively in adult bees. The lowest infection was statistically significant in Yeast candy group in June (4.35 million spores per bee, p=0.02), but insignificant in September. Supplementing artificial swarms Sugar candy offers the most promising potential for development of productive young colony. The findings of our study could help beekeepers to choose the effective candy supplement for optimal development of artificial swarms.

添加糖的幼蜜蜂(Apis mellifera carnica, Pollmann 1879)群落的性能和小孢子虫孢子水平
我们通过测量夏季成年蜜蜂的强度和小孢子虫孢子水平,评估了在人工蜂群中形成的年轻蜜蜂菌落中补充蛋白质、酵母或糖的效果。同时,在实验室控制条件下,对工蜂饲喂相同类型糖果后的寿命进行了研究。酵母糖和蛋白糖组的存活率最高。与此相反,实地研究表明,人工蜂群在第1期的蛹产量(2510.4 cm 2, p=0.0001)显著高于人工蜂群;在第2期,饲喂非蛋白糖的人工蜂群的幼虫产量(964.8 cm 2, p=0.003)显著高于人工蜂群的幼虫产量(5.6,p=0.008)。在第三期的年轻群体评价中,糖糖组的成蜂和蜜库覆盖帧数最高,分别为5.6个,p=0.0009;3432.0 cm 2, p=0.015)。糖糖组产生的蜡细胞面积最大,但差异没有统计学意义。定量测定了小孢子虫在成蜂体内的孢子水平。酵母糖组在6月份的孢子感染率最低,为435万个/只,p=0.02,但在9月份的感染率最低,无统计学意义。补充人工蜂群的糖糖提供了最有潜力的生产年轻群体的发展。本研究结果可以帮助养蜂人选择有效的糖补充剂,以优化人工蜂群的发育。关键词:蜜蜂;人工成群;年轻的殖民地;补充;糖果;发展;疾病spp。长寿RAZVOJ DRUŽIN IN ŠTEVILO SPOR Nosema spp. PRI MLADIH DRUŽINAH MEDONOSNE ČEBELE (Apis mellifera carnica, Pollmann 1879), KRMLJENIH S POGAČAMI izvle ek: Mlade ebelje družine iz umetnih rojev smo krmili z razli nimi poga ami z dodatkom beljakovin, kvasa ali sladkorja。Ocenjevali smo razvoj družin in dolo ali število孢子Nosema sp . pri odraslih ebelah v poletnem obdobju。V laboratorijskih pogojih smo kmili, ebele delavke, z。Najboljše preživetje smo ugotovili v skupinah, ki so prejele poga o s kvasom oziroma beljakovinami。nasprono pa je poskus v družinah pokazal, da je billion v 1。Obdobju merjenja bistveno veje bub (2510,4 cm 2, p = 0,0001), v 2。Obdobju pa veje liink (964,8 cm 2, p = 0,003) in okvirjev s ebelami (5,6, p = 0,008) pri krmljenju s sladkorno poga o。V 3。Obdobju ocenjevanja mladih družin je imela skupina s sladkorno poga o najveei pokritih okvirjev z odraslimi ebelami in zalog medu (5,6, p = 0,0009);3432,0 cm 2, p = 0,015)。Skupina ' s sladkorno poga o je zgradila najve jo površino satja, vendar razlike niso数据统计 no zna ilne。Število spor Nosema sp . je bilo kantitivativno preverjeno pri odraslih ebelah。Najnižja okužba je bila statistical no zna v skupini s poga_ o s kvasom v juniju(4,35万jna spor na ebelo, p = 0,02), september pa spore_ (9);Dodajanje sladkorne pobeljih družin.
