蚕豆由几种重要的大黄蜂授粉。油菜是由一个多样性的昆虫群落授粉的，它在空间和时间上都是变化的。改善授粉服务的管理应针对特定作物。昆虫授粉的大规模开花作物正变得越来越普遍，有必要了解哪些昆虫主要负责这些作物的授粉，以便在授粉昆虫减少的情况下采取适当的保护措施。本研究采用田间调查结合笼操作，以确定不同的传粉者类群的两个广泛开花作物，蚕豆和油菜授粉的相对贡献。花访问传粉者社区在现场观察到的每种作物是不同的，而外地豆类主要访问了几个熊蜂物种，多个传粉者类群访问油籽，这个传粉者社区的组成是高度可变的空间和时间。然而，在我们的研究区域，传粉者群落似乎都不能满足作物的需求。笼子里的操作表明，多种分类群可以有效地授粉油籽和外地豆类，但熊蜂是特别有效的豆授粉。结合田间观察和笼内操作表明，这两种大规模开花作物的授粉需求是高度对比的，一种将受益于管理，以增加一些关键类群的丰度，而对于另一种，提高整体传粉者的丰度和多样性将是更合适的。我们的研究结果强调了需要针对作物的缓解策略，旨在保护特定的传粉者类群（或类群），这些类群既活跃又能够进行作物授粉，以减少授粉赤字，满足未来作物生产的需求。
Field beans are pollinated by a few important bumblebee species. Oilseed rape is pollinated by a diverse insect community which varies spatially and temporally. Managment to improve pollination service should be targeted at specific crops. Insect pollinated mass flowering crops are becoming more widespread and there is a need to understand which insects are primarily responsible for the pollination of these crops so conservation measures can be appropriately targeted in the face of pollinator declines. This study used field surveys in conjunction with cage manipulations to identify the relative contributions of different pollinator taxa to the pollination of two widespread flowering crops, field beans and oilseed rape. Flower visiting pollinator communities observed in the field were distinct for each crop; while field beans were visited primarily by a few bumblebee species, multiple pollinator taxa visited oilseed, and the composition of this pollinator community was highly variable spatially and temporally. Neither pollinator community, however, appears to be meeting the demands of crops in our study regions. Cage manipulations showed that multiple taxa can effectively pollinate both oilseed and field beans, but bumblebees are particularly effective bean pollinators. Combining field observations and cage manipulations demonstrated that the pollination demands of these two mass flowering crops are highly contrasting, one would benefit from management to increase the abundance of some key taxa, whilst for the other, boosting overall pollinator abundance and diversity would be more appropriate. Our findings highlight the need for crop specific mitigation strategies that are targeted at conserving specific pollinator taxa (or group of taxa) that are both active and capable of crop pollination in order to reduce pollination deficits and meet the demands of future crop production.
