Abstract

For over a decade, high percentages of honey bee colonies have been perishing during the winter creating economic hardship to beekeepers and growers of early-season crops requiring pollination. A way to reduce colony losses might be moving hives into cold storage facilities for the winter. We explored factors that could affect the size and survival of colonies overwintered in cold storage and then used for almond pollination. The factors were when hives were put into cold storage and their location prior to overwintering. We found that colonies summered in North Dakota, USA and moved to cold storage in October were larger after cold storage and almond pollination than those moved in November. Colony location prior to overwintering also affected size and survival. Colonies summered in southern Texas, USA and moved to cold storage in November were smaller after cold storage and almond pollination than those from North Dakota. The colonies also were smaller than those overwintered in Texas apiaries. Fat body metrics of bees entering cold storage differed between summer locations. North Dakota bees had higher lipid and lower protein concentrations than Texas bees. While in cold storage, fat bodies gained weight, protein concentrations increased, and lipids decreased. The decrease in lipid concentrations was correlated with the amount of brood reared while colonies were in cold storage. Our study indicates that in northern latitudes, overwintering survival might be affected by when colonies are put into cold storage and that colonies summered in southern latitudes should be overwintered there.

冷库越冬蜜蜂(膜翅目:蜂科)种群的生存和生长:时间和种群位置的影响。
十多年来,蜂群在冬季死亡的比例很高,给养蜂人和需要授粉的早季作物种植者带来了经济困难。减少蜂群损失的一种方法可能是将蜂箱移到冷藏设施中过冬。本研究探讨了影响冷藏越冬后用于杏花授粉的蜂群大小和存活的因素。影响因素包括蜂箱在越冬前被放入冷库的时间和位置。我们发现,在美国北达科他的夏季,10月份移入冷库的蜂群在冷藏和杏花授粉后比11月份移入冷库的蜂群要大。越冬前的蚁群位置也影响其大小和存活率。在美国德克萨斯州南部避暑并于11月移至冷库的蜂群在冷库和杏仁授粉后比来自北达科他州的蜂群要小。这些蜂群也比那些在德克萨斯州养蜂场越冬的蜂群要小。进入冷库的蜜蜂的脂肪体指标在不同的夏季地点有所不同。北达科他州蜜蜂的脂肪含量高于德克萨斯州蜜蜂,蛋白质含量低于德克萨斯州蜜蜂。在冷藏期间,脂肪体体重增加,蛋白质浓度增加,脂质降低。脂质浓度的下降与菌落冷藏期间饲养的雏鸟数量有关。我们的研究表明,在北纬地区,蜂群的越冬生存可能受到冷藏时间的影响,而在南纬地区夏季的蜂群应该在那里越冬。
