野生昆虫传粉者的多样性和丰富度在许多农业景观中都有所下降。目前尚不清楚这种下降是否会降低作物产量，或者是被蜜蜂等有管理的传粉者缓解。我们发现，在全球41种作物系统中，果实结实与野生昆虫访花之间普遍存在积极的联系。相比之下，在接受调查的系统中，只有14%的系统随着蜜蜂访花而显著增加座果率。总体而言，野生昆虫为农作物授粉的效率更高；野生昆虫访花的增加促进了果实的结实，是蜜蜂访花的同等增加的两倍。野生昆虫和蜜蜂的来访促进了果实的独立结果，因此管理蜜蜂的授粉补充了野生昆虫的授粉，而不是取代了野生昆虫的授粉。我们的结果表明，对蜜蜂和不同的野生昆虫组合进行综合管理的新做法将提高全球作物产量。
The diversity and abundance of wild insect pollinators have declined in many agricultural landscapes. Whether such declines reduce crop yields, or are mitigated by managed pollinators such as honey bees, is unclear. We found universally positive associations of fruit set with flower visitation by wild insects in 41 crop systems worldwide. In contrast, fruit set increased significantly with flower visitation by honey bees in only 14% of the systems surveyed. Overall, wild insects pollinated crops more effectively; an increase in wild insect visitation enhanced fruit set by twice as much as an equivalent increase in honey bee visitation. Visitation by wild insects and honey bees promoted fruit set independently, so pollination by managed honey bees supplemented, rather than substituted for, pollination by wild insects. Our results suggest that new practices for integrated management of both honey bees and diverse wild insect assemblages will enhance global crop yields.
