中文摘要
一系列蚜虫传播的病毒降低了马铃薯种子和商品作物的价值。这些病毒通过蚜虫传播,例如桃-马铃薯蚜虫(Myzus persicae)和马铃薯蚜虫(Macrosiphum euphorphium)。近年来,随着主要杀虫剂的停用,生产足够的优质认证种子变得更加困难。由于蚜虫对现有杀虫剂产生了广泛的抗药性,使这种情况更加复杂。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,其中将间作或驱避剂施用于作物(”推“),并在主要作物周围种植高度吸引的诱捕作物,其作为害虫的诱饵(”拉“)。当有效应用时,这种方法可以最大限度地减少对作物的损害,并将害虫集中在使用开花带的天敌数量更多的田边。项目目标:通过开发“推拉”系统,改善马铃薯作物蚜虫害虫的管理。具体项目目标包括:确认积极的行为反应,例如蚜虫对一种或多种潜在诱捕作物的着陆行为;确认消极的行为反应,例如蚜虫对一种或多种植物精油和/或伴生作物的着陆行为;研究蚜虫在原型推拉系统中的着陆行为;优化推拉系统,例如修改诱捕作物中的植物混合物,诱捕作物植物的空间排列,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;在商业条件下优化推拉系统,与NIAB和CUPGRA的同事合作,以确保合适的网站。记录蚜虫数量和作物内病毒传播
英文摘要
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.
