1.有弹性的授粉服务有赖于随着时间的推移有足够数量的授粉昆虫。然而，目前关于传粉者的现状和趋势的大多数知识仅基于传粉者物种丰富度和分布的变化。迫切需要对传粉者进行系统、长期的监测，以提供有关其状况的基线信息，查明导致传粉者数量下降的驱动因素，并提供适当的应对措施。能量分析被用来确定在10年内检测传粉者种群30%变化所需的地点数量。然后，我们评估了在英国实施四个国家监测计划的全部经济成本：(A)专业传粉者监测，(B)专业传粉服务监测，(C)志愿者收集的捕蝇器和(D)志愿者重点观察花卉。这些成本与(A)实施独立的、专家设计的研究和监测网络的成本和(B)授粉服务的经济效益受到传粉者损失的威胁进行了比较。估计的计划成本从75个地点的志愿者焦点花卉观察计划的6159英镑/年到800个地点的专业授粉服务监测网络的2.7英镑/年不等。使用站点网络作为研究基础设施节省的研究成本估计在1.46-4.17英镑/年之间。在传粉者减少30%之后，英国农作物产量损失的经济价值估计类似于188英镑/年。合成与应用。我们评估了实施传粉者监测计划的全部成本，以及它们为研究和社会提供的经济利益。每年的监控成本为
1. Resilient pollination services depend on sufficient abundance of pollinating insects over time. Currently, however, most knowledge about the status and trends of pollinators is based on changes in pollinator species richness and distribution only.2. Systematic, long-term monitoring of pollinators is urgently needed to provide baseline information on their status, to identify the drivers of declines and to inform suitable response measures.3. Power analysis was used to determine the number of sites required to detect a 30% change in pollinator populations over 10 years. We then evaluated the full economic costs of implementing four national monitoring schemes in the UK: (a) professional pollinator monitoring, (b) professional pollination service monitoring, (c) volunteer collected pan traps and (d) volunteer focal floral observations. These costs were compared to (a) the costs of implementing separate, expert-designed research and monitoring networks and (b) the economic benefits of pollination services threatened by pollinator loss.4. Estimated scheme costs ranged from 6,159 pound/year for a 75-site volunteer focal flower observation scheme to 2.7 pound M/year for an 800-site professional pollination service monitoring network. The estimated research costs saved using the site network as research infrastructure range from 1.46-4.17 pound M/year. The economic value of UK crop yield lost following a 30% decline in pollinators was estimated at similar to 188 pound M/year.5. Synthesis and applications. We evaluated the full costs of running pollinator monitoring schemes against the economic benefits to research and society they provide. The annual costs of monitoring are
