“…It rather suggests that observed enhancement of pest predation observed here at higher shares of greening was apparently not strong enough that it translated in significant effects on final crop yield. Insect pollination, although enhanced by local and landscape‐scale greening, seemed not to play a significant role for final crop yield, in our study presumably because seed set in the studied OSR variety is not as strongly limited by insect pollination as in other varieties in which the contribution of insect pollination ranges between 13% and 50% (Hudewenz et al., ; Marini et al., ; Sutter & Albrecht, ). The relatively low pollinator dependence of the investigated variety together with strong effects of management are likely the main reasons for the lack of interactive effects among pollination and natural pest control services found in the present study, despite experimental evidence for strikingly strong interactive effects among pollination and pest control shaping final yield of another OSR variety (Sutter & Albrecht, ).…”

The explicit and implicit aims of creating ecological focus areas (EFAs) and implementing greening measures in European agro‐ecosystems include the promotion of regulatory ecosystem services (ES) to sustain crop production in conventional cropping systems. However, the extent to which these goals are achieved with current policy measures remains poorly explored. We measured insect‐mediated pollination and natural pest control service provisioning in 18 winter oilseed rape fields as a function of the independent and interactive effects of local EFA establishment─sown wildflower strips and hedgerows─and landscape‐scale greening measures within a 1 km radius around focal fields and quantified their contribution to crop yield. Insect pollination potential and pest predation increased on average by 10% and 13%, respectively, when landscape‐scale greening measures share was increased from 6% to 26%. For pollination, the increase was stronger in fields adjoining an EFA (14%) than in fields without adjacent EFA (7%). Agricultural management practices were the main drivers of crop yield. Neither insect pollination potential or natural pest control (pest predation and parasitism) nor adjacent EFAs and landscape‐scale greening significantly affected crop yield in addition to agricultural management. Synthesis and applications. Local establishment of perennial, species‐rich wildflower strips and hedgerows, combined with landscape‐scale greening measures in agricultural landscapes, can promote multiple ecosystem services (ES) in conventional production systems. Benefits may be maximized when local and landscape measures are combined. However, enhanced pollination and natural pest regulation seem to contribute relatively little to final crop yield compared to local agricultural management practices in the high‐input conventional production system studied. Further research is needed to better understand how to improve the effectiveness of ecological focus areas and other greening measures in promoting regulatory ES. Potential improvements include minimising trade‐offs while promoting synergies between ES provision, food production and biodiversity conservation.

Summary1. Above-ground and below-ground environmental conditions influence crop yield by pollination, pest pressure and resource supply. However, little is known about how interactions between these factors contribute to yield. Here, we used oilseed rape Brassica napus to test their effects on crop yield. 2. We exposed potted plants to all combinations of high and low levels of soil organic matter (SOM) and fertilizer supply, and placed all treatments at a variety of field sites representing a gradient in pollinator visitation rate and pest exposure. We determined the relative contribution of pollinators and pests, SOM and fertilizer supply to yield. We also tested whether SOM can moderate effects of fertilizer on yield and whether soil conditions influence the relationship between above-ground conditions and yield. 3. Increases in pollinator visitation rate and decreases in pest pressure enhanced yield more than increase in fertilizer supply. Although higher SOM content resulted in plants with more biomass and flowers, under our experimental conditions SOM neither enhanced yield, nor influenced effects of fertilizer, pollinators or pests on yield. 4. The relationships between yield, pollinator visitation rate and pest pressure did not depend on the level of fertilization, suggesting that the effects of fertilizer application and aboveground (dis)services on yield were additive. In contrast, pollinator visitation rate was more strongly related to yield at low pest pressure than at high pest pressure indicating trade-offs between above-ground services and disservices. 5. Synthesis and applications. Our results show that it is possible to increase oilseed rape yield by enhancing pollination, irrespective of supplying mineral fertilizer. Moreover, the fact that belowground conditions did not alter the effect of above-ground conditions suggests that farmers may obtain even higher yields by maximizing both above-ground ecosystem services and external inputs. Further studies are needed to understand at which point the positive relationships between pollinator visitation and yield, as well as between fertilizer and yield, will level off. Considering above-ground and below-ground services and inputs in agro-ecosystems in conjunction is crucial in order to optimize external inputs for crop yield from an economic and ecological perspective.

“…cabbage and other brassicas, carrots, turnips, lettuce, chicory and onions) increases the quality of the seed production (Gallai and Vassière 2009). In addition, insect pollinators enhance fruit and seed quality Bartomeus et al 2014;Garratt et al 2014;Marini et al 2015;Saeed et al 2016) and reinforces pest management (Cross et al 2015) which constitutes an indirect and difficult benefit to measure, but extremely important for the agricultural market. Also, a recent study on pollination by wild insect pollinators has showed their capacity to increase the seed production in 41 agricultural systems globally, regardless of the abundance of honey bees .…”

Insect pollinators provide vital ecosystem services through its maintenance of plant biological diversity and its role in food production. Indeed, adequate pollination services can increase the production and quality of fruit and vegetable crops. This service is currently challenged by land use intensification and expanding human population growth. Hence, this study aims: (1) to assess the pollination services in different land uses with different levels of disturbance through GIS mapping technique using insect pollinators abundance and richness as indicators, and (2) estimate the economic value of pollination by insects in agricultural crops. Our study takes place in a small oceanic island, Terceira (Azores, Portugal). Our results showed, remarkably, that not only the pristine vegetation areas, but also the orchards and agricultural areas have relatively high values of pollination services, even though both land uses have opposite disturbance levels. For the economic valuation, we analyzed 24 crops in the island and found that 18 depend on pollinators with one-third of these crops having 65% or 95% dependence on pollinators. The economic contribution of pollinators totals 36.2% of the total mean annual agricultural income of the dependent crops, highlighting the importance of insect pollinators in agricultural production and consequent economic gain productions.
