Raspberry is a popular and high-value soft fruit in the UK. However, current production is hampered by aphid infestation, mainly attributed to the large raspberry aphid (_Amphorophora idaei_). Controlling this aphid was historically done by breeding aphid-resistant raspberry cultivars and spraying pesticides. However, these methods are no longer adequate for several reasons. First, aphid biotypes able to withstand genes bred into raspberry began to emerge. Additionally, breeding for aphids for resistance is no longer a priority due to fewer concerns about the viruses that aphids spread. Secondly, the withdrawal of approvals for pesticides has limited the options for control.Control of aphids is now anchored on integrated pest management strategies that depend on the use of effective commercially produced biocontrol products such as parasitoids and generalist predators. However, research has not been done to align the effectiveness of different biocontrol components into a cohesive integrated biocontrol program to protect raspberry crops from aphids. Consequently, there are losses to production, wastage of unmarketable fruit and inefficient resource use in raspberry. Commercial losses of even 10% to this £147M/year industry would translate to over £14M losses, an unacceptably high sum given that the UK imports more than 69% of raspberries consumed locally.This project will leverage the expertise of grower organisations, NIAB scientists and a leading biocontrol producer to develop and test an integrated biocontrol program for aphid control in raspberry. The overall aim is to incorporate different biocontrol components into a season-long program that is responsive to the seasonal changes in the plant and aphids. We will include additional monitoring to assess the natural enemies and pests which utilise the crop during the winter season. This expanded scope is valuable to raspberry growers in the UK for aphid management and aligns with current thinking on maintaining " a standing army" of natural enemies of aphid in raspberry plantations. Additionally, the research consortium will conduct a cost-benefit analysis to ensure that adequate control maintains the market competitiveness of locally produced raspberries. Furthermore, this research will provide valuable information and data for future research to create biocontrol programs for other soft fruit in the UK.

覆盆子在英国是一种受欢迎的高价值软果，但目前的生产受到蚜虫侵扰的阻碍，主要归因于大型覆盆子蚜虫（_Amphorophora idaei_），历史上是通过培育抗蚜虫覆盆子品种来控制这种蚜虫的。然而，由于多种原因，这些方法不再适用。首先，能够抵抗覆盆子基因的蚜虫生物型开始出现。此外，由于对蚜虫传播的病毒的担忧减少，培育蚜虫以提高抗性已不再是首要任务。其次，农药审批的撤销限制了控制的选择。现在，蚜虫的控制以综合害虫管理为基础。依赖于使用有效的商业生产的生物防治产品（例如寄生蜂和多面性捕食者）的策略然而，尚未进行研究以将不同生物防治成分的有效性整合为一个有凝聚力的综合生物防治计划以保护覆盆子。经测试，覆盆子的生产损失、滞销水果的浪费和资源利用效率低下，对这个价值 1.47 亿英镑/年的产业来说，即使是 10% 的损失也将超过 1400 万英镑，这是一个令人无法接受的高额损失。英国超过 69% 的本地消费覆盆子是进口的。该项目将利用种植者组织、NIAB 科学家和领先的生物防治生产商的专业知识来开发和测试综合生物防治计划总体目标是将不同的生物防治成分纳入响应植物和蚜虫季节变化的整个季节计划中，以评估利用作物的天敌和害虫。这一扩大的范围对于英国覆盆子种植者的蚜虫管理很有价值，并且符合当前在覆盆子种植园中维持蚜虫天敌“常备军”的想法。联盟将进行成本效益分析，以确保适当的控制保持当地生产的覆盆子的市场竞争力。此外，这项研究将为未来的研究提供有价值的信息和数据，为英国其他软果制定生物防治计划。
