UK berry production contributed £629M to the economy in 2021, increasing income by a third within 10 years. Berry production is also essential for human health as high-value and high-quality fruits provide a range of antioxidants, vitamins and fibre. However, berry production faces challenges in production related to a range of emerging and increasing pests and diseases. The global soft fruit industry suffers significant crop losses from an invasive fruit fly, spotted wing drosophila (SWD). SWD lays eggs in fruit before it is harvested, causing up to 80% crop loss. The potential market in the UK, Europe and USA for SWD control is £11bn. High value crops like strawberry, cherries, blueberries, blackberries and raspberries, are reliant on chemical insecticides to protect them from SWD.In previous work, we have already identified a candidate repellent for SWD and a trapping system to remove SWD from fruit crops. In this project we will test a combination of these two approaches in a 'push-pull' strategy; 'pushing' SWD out of the crop and 'pulling' it away from the crop to reduce direct damage to fruits before they are harvested. Our approach is a more targeted and less environmentally damaging method to SWD control. We will first test our push-pull system with two major English fruit growers in commercial strawberry crops and we will begin to test on crops even more attractive to SWD, like raspberry. Reduction in fruit damage by SWD will be quantified and effects on beneficial insects minimised. In parallel work, novel biodegradable formulations of the repellent will be developed, lures in the traps further improved and deployment patterns for both repellent and traps optimised.This push-pull strategy will be a first for this global pest and enable fruit growers to improve productivity cost-effectively and sustainably by reducing insecticide applications and residues in saleable fruit, reducing labour inputs, and contributing to the progression to net zero. The project will be led by Russell IPM, the UK's largest producer of biorational approaches to control of pests and diseases who will exploit this potentially game-changing solution to SWD. Two major English growers, Rumwood Green Farms Ltd. and WB Chambers and Son, will provide facilities and labour for carrying out field trials. Academic partners are NIAB who are world leaders in applied SWD research, and NRI, University of Greenwich, will work with Russell to develop new attractants and repellent formulations.

2021 年，英国浆果生产为经济贡献了 6.29 亿英镑，收入在 10 年内增加了三分之一，因为高价值和高质量的水果提供了一系列抗氧化剂、维生素和纤维。浆果生产面临着与一系列新出现和不断增加的病虫害有关的挑战，全球软果产业因入侵果蝇、斑翅果蝇 (SWD) 产卵而遭受重大农作物损失。在英国、欧洲和美国，SWD 控制的潜在市场价值达 110 亿英镑，草莓、樱桃、蓝莓、黑莓和覆盆子等高价值作物都依赖化学品。在工作中，我们已经确定了一种候选的 SWD 驱避剂和一个捕获系统，以从水果作物中去除 SWD。在这个项目中，我们将测试这两种先前方法的组合。 “推拉”策略；将 SWD 从作物中“推”出，然后将其从作物中“拉”出来，以减少在收获前对水果的直接损害。我们将首先在商业草莓作物上测试我们的两个主要英国水果种植者的推拉系统，然后我们将开始测试对 SWD 更具吸引力的作物，例如覆盆子，将量化 SWD 对水果损害的减少和影响。在并行工作中，将开发新型可生物降解的驱虫剂配方，进一步改进诱捕器中的诱饵，并优化驱虫剂和诱捕器的部署模式。这种推拉策略将是针对这种全球性害虫的首个策略。该项目将由 Russell IPM 领导，通过减少杀虫剂的使用和可售水果中的残留、减少劳动力投入以及促进实现净零排放，以经济高效且可持续的方式提高生产力。英国最大的病虫害生物合理控制生产商将向 SWD 利用这一可能改变游戏规则的解决方案，两家主要的英国种植商 Rumwood Green Farms Ltd. 和 WB Chambers and Son 将为进行田间试验提供设施和劳动力。学术合作伙伴是 NIAB，他们是应用 SWD 研究领域的世界领先者，NRI、格林威治大学将与 Russell 合作开发新的引诱剂和驱虫剂配方。
