1.人们越来越认识到，授粉不足正在限制世界范围内的作物产量。然而，对于大多数作物来说，昆虫最佳授粉的管理策略仍然不清楚。目前的管理侧重于提供高密度蜜蜂，但建议的密度高度可变，即使在单一作物和品种内也是如此。2.我们进行了广泛的文献检索，以记录蜜蜂密度(蜂群密度和/或访花率)和作物生产力(座果率、结实率、果重和/或产量)。效应大小被表示为两个最极端的蜜蜂密度水平之间的作物生产力差异。3.在795项回顾研究中，只有22项分析了至少两个水平的蜜蜂密度对作物生产力的影响(报告了60项由此产生的影响
1. There is increasing recognition that pollination deficits are limiting crop yields world-wide. However, management strategies for optimal insect pollination are still unclear for most crops. Current management focuses on providing high densi ties of honeybees, but recommended densities are highly variable, even within single crops and cultivars. 2. We performed an extensive literature search to record honeybee densities (col ony density and/or flower visitation rates) and crop productivity (fruit set, seed set, fruit weight and/or yield). Effect sizes were represented as the difference in crop productivity between the two most extreme levels of honeybee densities. 3. Out of 795 reviewed studies, only 22 analysed the effect of at least two levels of honeybee densities on crop productivity (reporting 60 resulting effect
