昆虫授粉是一种经过充分研究的生态系统服务，支持全球75%的重要作物的生产。虽然产量是由一系列生态系统服务和管理因素维持和调节的，但授粉对产量的贡献大多是孤立研究的。在这里，我们汇编和审查的研究授粉作物产量的贡献在不同的环境条件下，授粉和其他因素之间的潜在相互作用，如养分供应和控制害虫，产量进行了测试。具体而言，我们探讨了授粉是否显示协同，补偿或添加剂的影响与伴随因素。文献检索得到了24项同行评审研究，共39项相互作用试验。研究审查了13种作物的反应，测试了当地和景观尺度的相互作用。授粉和其他影响产量的因素之间的相互作用，观察到几种作物，大多数显示出正协同关系。作物生活史性状，如授粉依赖性被发现影响植物对资源和花粉可用性变化的反应。土壤性质和作物害虫可能会影响授粉产量的贡献，通过改变资源的数量，植物可以分配到繁殖，独立的花粉量提供。目前的管理策略，以提高传粉者可能无法增加授粉效益的景观特点是土壤资源贫乏或无效的害虫防治。我们建议，我们的理解作物授粉相互作用的影响将受益于集中在植物性状和生理反应。需要将植物生理学和生态学知识与农业技术进步相结合，以设计新的管理战略，最大限度地提高授粉效益，支持产量，减少粮食生产对环境的影响。
Insect pollination is a well-studied ecosystem service that supports production in 75% of globally important crops. Although yield is known to be sustained and regulated by a bundle of ecosystem services and management factors, the contribution of pollination to yield has been mostly studied in isolation. Here, we compiled and reviewed research on the contribution of pollination to crop yield under different environmental conditions, where the potential interaction between pollination and other factors contributing to yield, such as nutrient availability and control of pests, was tested. Specifically, we explored whether pollination displayed synergistic, compensatory or additive effects with concomitant factors. The literature search resulted in 24 peer-reviewed studies for a total of 39 individual tests of interactions. Studies examined responses in 13 crops testing interactions both at the local and the landscape scale. Interactions between pollination and other factors influencing yield were observed for several crops and mostly displayed positive-synergistic relationships. Crop life-history traits such as pollination dependency were found to affect the plant response to variations in resource and pollen availability. Soil properties and crop pests might affect contribution of pollination to yield by altering the amount of resources a plant can allocate to reproduction, independently of the amount of pollen provided. Current management strategies to enhance pollinators might fail to increase pollination benefits in landscapes characterized by poor soil resources or ineffective pest control. We propose that our understanding of the effects of crop-pollinator interactions will benefit by focusing on plant traits and physiological responses. Combining knowledge from plant physiology and ecology with technological advances in agriculture is needed to design novel management strategies to maximize pollination benefits and support yields and reduce environmental impacts of food production.
