Over the last quarter century, increasing honey bee colony losses motivated standardized large-scale surveys of managed honey bees (Apis mellifera), particularly in Europe and the United States. Here we present the first large-scale standardized survey of colony losses of managed honey bees and stingless bees across Latin America. Overall, 1736 beekeepers and 165 meliponiculturists participated in the 2-year survey (2016-2017 and 2017-2018). On average, 30.4% of honey bee colonies and 39.6% of stingless bee colonies were lost per year across the region. Summer losses were higher than winter losses in stingless bees (30.9% and 22.2%, respectively) but not in honey bees (18.8% and 20.6%, respectively). Colony loss increased with operation size during the summer in both honey bees and stingless bees and decreased with operation size during the winter in stingless bees. Furthermore, losses differed significantly between countries and across years for both beekeepers and meliponiculturists. Overall, winter losses of honey bee colonies in Latin America (20.6%) position this region between Europe (12.5%) and the United States (40.4%). These results highlight the magnitude of bee colony losses occurring in the region and suggest difficulties in maintaining overall colony health and economic survival for beekeepers and meliponiculturists.
在过去的四分之一个世纪里,蜜蜂群的大量减少促使人们对管理性的蜜蜂(Apis mellifera)进行了标准化的大规模调查,尤其是在欧洲和美国。在这里,我们首次对拉丁美洲管理性蜜蜂和无刺蜂的蜂群损失进行了大规模标准化调查。总体而言,在为期两年的调查(2016-2017 年和 2017-2018 年)中,共有 1736 名养蜂人和 165 名蜜蜂蜜蜂养殖者参与。平均而言,该地区每年有 30.4%的蜜蜂蜂群和 39.6%的无刺蜂群损失。无刺蜂的夏季损失高于冬季损失(分别为 30.9%和 22.2%),而蜜蜂的夏季和冬季损失则没有差异(分别为 18.8%和 20.6%)。在夏季,无论是蜜蜂还是无刺蜂,蜂群规模越大,损失率越高,而在冬季,无刺蜂的蜂群规模越大,损失率越低。此外,无论是养蜂人还是蜜蜂蜜蜂养殖者,其损失在不同国家和年份之间都有显著差异。总体而言,拉丁美洲的蜜蜂冬季蜂群损失(20.6%)使该地区处于欧洲(12.5%)和美国(40.4%)之间。这些结果突出了该地区蜜蜂群损失的规模,并表明养蜂人和蜜蜂蜜蜂养殖者在维持总体蜂群健康和经济生存方面存在困难。
