To gauge the impact of COVID-19 on the Canadian beekeeping sector, we conducted a survey of over 200 beekeepers in the fall of 2020. Our survey results show Canadian beekeepers faced two major challenges: 1) disrupted importation of honey bees (Hymenoptera: Apidae) (queen and bulk bees) that maintain populations; and 2) disrupted arrival of temporary foreign workers (TFWs). Disruptions in the arrival of bees and labor resulted in fewer colonies and less colony management, culminating in higher costs and lower productivity. Using the survey data, we develop a profitability analysis to estimate the impact of these disruptions on colony profit. Our results suggest that a disruption in either foreign worker or bee arrival allows beekeepers to compensate and while colony profits are lower, they remain positive. When both honey bee and foreign workers arrivals are disrupted for a beekeeper, even when the beekeeper experiences less significant colony health and cost impacts, a colony with a single pollination contract is no longer profitable, and a colony with two pollination contracts has significantly reduced profitability. As COVID-19 disruptions from 2020 and into 2021 become more significant to long-term colony health and more costly to a beekeeping operation, economic losses could threaten the industry's viability as well as the sustainability of pollination-dependent crop sectors across the country. The economic and agricultural impacts from the COVID-19 pandemic have exposed a vulnerability within Canada's beekeeping industry stemming from its dependency on imported labor and bees. Travel disruptions and border closures pose an ongoing threat to Canadian agriculture and apiculture in 2021 and highlight the need for Canada's beekeeping industry to strengthen domestic supply chains to minimize future risks.
为了评估 COVID-19 对加拿大养蜂业的影响,我们在 2020 年秋季对 200 多名养蜂人进行了调查。我们的调查结果显示,加拿大养蜂人面临两大挑战:1)进口蜜蜂(膜翅目:蜂科)(蜂王和大批蜜蜂)受到干扰,以维持蜂群数量;2)临时外国工人(TFWs)的到来受到干扰。蜜蜂和劳动力的到来受到干扰,导致蜂群数量减少,蜂群管理减少,最终导致成本增加和生产力降低。利用调查数据,我们进行了盈利能力分析,以估计这些干扰对蜂群利润的影响。我们的研究结果表明,外国工人或蜜蜂到达的任何一方受到干扰,养蜂人都可以进行补偿,虽然蜂群利润较低,但仍为正。当养蜂人的蜜蜂和外国工人的到达都受到干扰时,即使养蜂人经历的蜂群健康和成本影响较小,有单一授粉合同的蜂群不再盈利,有两个授粉合同的蜂群的盈利能力则显著降低。随着 COVID-19 对 2020 年和 2021 年的长期蜂群健康的影响以及对养蜂业务的成本增加,经济损失可能会威胁到该行业的生存能力以及全国授粉依赖型作物部门的可持续性。COVID-19 大流行带来的经济和农业影响暴露了加拿大养蜂业的脆弱性,其原因是该行业依赖进口劳动力和蜜蜂。2021 年,旅行中断和边境关闭对加拿大农业和养蜂业构成持续威胁,突显了加拿大养蜂业需要加强国内供应链,以最大限度地减少未来风险。
