To protect sweet cherry (Prunus avium L.) against pests in commercial orchards, pesticides are frequently used, but some have adverse environmental impacts. Natural enemies can deliver protection against pests but compared to the surrounding non-crop habitat their abundance is usually low in intensively managed agricultural systems. Wildflower interventions established for Conservation Biological Control as part of Integrated Pest Management (IPM) can reinstate habitat for natural enemies within cropped areas and enhance natural pest control. Over a three-year period, this more sustainable approach to crop protection was investigated in eight sweet cherry orchards protected under polytunnels in the West Midlands (UK). Wildflower strips were established in alleyways between rows of cherry trees and managed under two cutting regimes, Standard Wildflower Strips (SWS) (a single cut in late September) and Actively Managed Wildflower Strips (AMWS) (regularly cut to a height of 20 cm throughout the growing season). These were compared to unsown Control Strips (CS) (original vegetation dominated by grass species). To investigate natural enemy populations and pest regulation services, direct search, Vortis suction sampling, beat sampling, and aphid bait cards were used. Araneae (40.0% of records) and parasitoid wasps (22.7%) were the most frequent natural enemies recorded in alleyways, whilst Anystidae (51.8%) and Araneae (20.8%) were most abundant on cherry trees. Wildflower treatments almost doubled the abundance of natural enemies in alleyways, and increased abundance in cherry trees by ~15% compared to the CS. Wildflower strips increased predation of aphids (bait cards) in cherry trees by 25%. No difference in natural enemy abundance, richness or pest control was recorded between the two wildflower management regimes. Differences in natural enemy abundance and predation rates were detected despite the continued use of pesticides by growers (an average of 5.4 (± 0.4) applications per orchard per year). This study demonstrates that creating wildflower habitat in commercial sweet cherry orchards under polytunnels can boost natural enemies and the associated pest regulation services. Relative to CS, the novel grower-friendly approach of maintaining wildflower strips at a height of 20 cm with regular cutting increased flower resource availability and pest regulation services, demonstrating the potential for growers to adopt this approach as part of a robust IPM strategy.

保护甜樱桃（李属樱桃）L.）针对商业果园中的害虫，农药经常使用，但有些会对环境造成不利影响。天敌可以提供对害虫的保护，但与周围的非作物生境相比，在集约化管理的农业系统中，它们的丰度通常较低。作为病虫害综合治理（IPM）的一部分而建立的用于保护生物防治的野花干预措施，可以恢复种植区域内天敌的栖息地，并增强自然害虫的防治能力。在三年的时间里，在西米德兰兹郡（英国）的八座甜樱桃园中，采用了这种更可持续的农作物保护方法，并对其进行了研究。在两排樱桃树之间的小巷中建立了野花条，并在两种切割方式下进行管理，标准野花条（SWS）（9月下旬一次切割）和主动管理的野花条（AMWS）（在整个生长季节通常切成20厘米的高度）。将这些与未播种的控制带（CS）（草种占主导地位的原始植被）进行了比较。为了调查天敌种群和虫害治理服务，使用了直接搜索，Vortis吸取采样，节拍采样和蚜虫诱饵卡。在小巷中，最常见的天敌是Araneae（占记录的40.0％）和拟寄生蜂（22.7％），而樱桃树上的Anystidae（51.8％）和Araneae（20.8％）最丰富。与CS相比，野花处理几乎使小巷中天敌的丰度提高了一倍，并使樱桃树的丰度提高了约15％。野花条使樱桃树中的蚜虫（诱饵卡）捕食增加了25％。在两种野花管理制度之间，天敌的丰度，丰富度或害虫控制没有差异。尽管种植者继续使用农药，但仍发现天敌的丰度和捕食率存在差异（每个果园每年平均施用5.4（±0.4）剂）。这项研究表明，在多通道下的商业甜樱桃园中建立野花栖息地可以促进天敌和相关的害虫调节服务。相对于CS，一种新颖的对种植者友好的方法，可以将野花条保持在20厘米的高度，并定期进行切割，以增加花卉资源的利用率和病虫害防治服务，
