Plant pest prevention through technology-guided monitoring and site-specific control

欧盟要求根据针对检疫、优先和其他严重有害生物的创新检测理念，迅速采取有效行动。由于气候变化和对高质量、无害虫食品的需求日益增长，公平、健康和环境友好的食品体系正受到越来越多的虫害入侵的威胁。PurPest的目标是开发、验证和演示一种创新的传感器平台，该平台可以在进口和田间快速检测五种不同的害虫，阻止它们的建立，并将农药投入减少至少50%。传感器的概念是基于对被一种或几种害虫入侵的寄主植物排放的害虫特有的挥发性有机化合物(VOC)的检测。PurPest将在不同的非生物胁迫条件下测定松疫霉菌、秋季粘虫、棉铃虫、褐飞虱和松材线虫的VOC特征。将利用VOC数据库优化现有传感器概念并开发新的传感器概念，以检测特定于害虫的VOCs，从概念验证(TRL3)到田间试验示范(TRL6)。非侵入性、可靠、快速的有害生物传感平台将把有害生物筛选效率从目前植物进口的3%提高到80%。通过早期发现防止新害虫的暴发和现场特定农药的使用是可持续和综合害虫管理(IPM)的基石。PurPest将评估5种害虫的社会经济和生态影响，以及新的检测概念如何影响这些影响。通过咨询委员会、研讨会和网络研讨会与利益攸关方直接沟通是PurPest多行为者方法的一部分，以确认价值链上所有利益集团的参与。PurPest项目是一个强大的多学科联盟，拥有来自10个国家、7所大学、5个研究机构、4个中小企业和2个政府机构的专业知识。

The EU requires rapid and effective actions based on innovative detection concepts targeting quarantine, priority and other serious pests. Fair, healthy and environment-friendly food systems are threatened by increasing pest invasions due to climate change and a growing demand for high quality, pest-free food. The goal of PurPest is to develop, validate and demonstrate an innovative sensor platform that can rapidly detect five different pests during import and in the field to stop their establishment and reduce pesticide inputs by at least 50%. The sensor concept is based on detection of pest-specific volatile organic compounds (VOCs) emitted by host plants invaded by one or several pests. PurPest will determine the VOC signature of Phytophthora ramorum, the Fall armyworm, the Cotton bollworm, the Brown marmorated stinkbug and the Pinewood nematode under different abiotic stress conditions. The VOC database will be exploited to optimize existing and develop new sensor concepts to detect pest-specific VOCs, starting from proof of concept (TRL3) to demonstration in field trials (TRL6). Non-invasive, reliable and rapid pest sensing platforms will increase pest screening efficiency from currently 3% to 80% of plant imports. Preventing outbreaks of new pests and site-specific pesticide use by early detection are the cornerstones of sustainable and integrated pest management (IPM). PurPest will evaluate the socio-economic and ecological impact of 5 pests and how the new detection concept affectsthese impacts. Direct communication with stakeholders via the advisory board, workshops and webinars is part of PurPest’s multi-actor approach to affirm involvement of all interest groups along the value chain The PurPest project is a strong multidisciplinary consortium with expertise from 10 countries, 7 universities, 5 research institutes, 4 SMEs and 2 governmental agencies.
