To me, to you developing a push pull system for sustainable management of aphid pests in seed and ware potato crops

一系列蚜虫传播的病毒降低了马铃薯种子和果实的价值。这些病毒是通过蚜虫传播的，如桃子-马铃薯蚜虫（桃蚜）和马铃薯蚜虫（大黄蚜）。近年来，随着主要杀虫剂的退出，生产足够的高质量认证种子变得更加困难。由于蚜虫种群对现有杀虫剂产生了广泛的抗药性，这种情况更加严重。迫切需要有效的替代品，以尽量减少病毒在马铃薯作物中的传播。“推-拉”或“刺激-威慑转移”是一种作物保护方法，在作物上施用间作或驱避剂（“推”），并在主要作物周围种植具有高度吸引力的诱捕作物，作为害虫的诱饵（“拉”）。如果有效地使用这种方法，可以将对作物的损害降到最低，并将害虫集中在农田边缘，因为在这些地方，天敌较多，而在使用开花条的地方。项目目标：通过开发一种“推拉”系统来改善马铃薯作物蚜虫的管理。具体项目目标包括：确认积极的行为反应，例如蚜虫落在一种或多种潜在诱捕作物上的行为；确认负面行为反应，例如蚜虫对一种或多种植物精油和/或伴生作物的降落行为；在原型推挽系统中研究蚜虫的着陆行为；优化推挽系统，例如修改诱捕作物内的植物混合物，诱捕作物植物的空间安排，使用植物精油的新配方（纳米配方和微胶囊技术）作为驱避剂；与NIAB和CUPGRA的同事合作，在商业条件下优化推拉系统，以确保合适的场地。记录作物内蚜虫数量和病毒传播情况

The value of seed and ware potato crops is reduced by a range of aphid transmitted viruses. These viruses are transmitted aphids, such as the peach-potato aphid (Myzus persicae) and the potato aphid (Macrosiphum euphorbiae). Production of sufficient high-quality certified seed has become more difficult in recent years with the withdrawal of key insecticides. This situation has been compounded by development of widespread resistance in aphid populations to available insecticides. Effective alternatives are urgently required in order to minimise the spread of viruses in potato crops. 'Push-pull' or 'stimulo-deterrent diversion' is a crop protection method in which an intercrop or repellent is applied to the crop ('push') and a highly attractive trap crop is grown around the main crop, which acts as a lure for the pest ('pull'). When effectively applied this approach minimises damage to the crop and concentrates the pest in field margins where natural enemies are more numerous where flowering strips are used. Project aim: to improve management of aphid pests of potato crops through development of a 'push-pull' system.Specific project objectives include; confirming positive behavioural responses, e.g. landing behaviour of aphids to one or more potential trap crops; confirming negative behavioural responses, e.g. landing behaviour of aphids to one or more plant essential oils and/or companion crops; investigating aphid landing behaviour within prototype push-pull systems; optimising push-pull systems e.g. modifying plant mixes within trap crop, spatial arrangement of trap crop plants, use of novel formulations of plant essential oils (nano-formulations and microencapsulation technologies) as repellents; optimising push-pull system under commercial conditions working with colleagues at NIAB and CUPGRA to secure suitable sites.
