项目摘要

Spotted wing Drosophila, Drosophila suzukii, originated in the Far East but has recently appeared as an invasive pest inthe USA and Europe. Unlike most other Drosophila species which attack only ripe and overripe fruit and are of littleeconomic importance as pests in a commercial situation, D. suzukii can attack ripening fruit and is threatening to becomethe single most damaging pest of soft and stone fruit in Europe and the USA. Females lay eggs in fruit before harvest andthe larvae feed inside causing rapid degradation in fruit quality, rendering it unmarketable. Current commercially-availablebaits are based on ripe or fermenting volatiles from host fruits, but they are not competitive with the ripening fruit crops andare not specific to D. suzukii. This project will test the hypothesis that D. suzukii is unusual among fruit flies in beingattracted to volatiles from plants with ripening fruits and that the volatiles responsible can be used to develop a lure that ismore attractive and much more specific for D. suzukii than existing lures. Such a lure would find world-wide application inmonitoring and control of this pest. This innovative approach brings together UK fruit growers and a producer organisation,Berry Gardens Growers, a manufacturer, Real IPM, and scientists from two research organisations, East Malling Researchand the Natural Resources Institute of the University of Greenwich.

斑点翼果蝇，铃木果蝇，起源于远东，但最近在美国和欧洲被认为是一种入侵害虫。不同于大多数其他果蝇物种，它们只攻击成熟和过熟的果实，在商业情况下作为害虫的经济重要性很小，铃木果蝇可以攻击成熟的水果，并有可能成为欧洲和美国软果和核果类水果的最具破坏性的单一害虫。雌性在收获前在果实中产卵，幼虫在里面取食，导致水果质量迅速下降，使其滞销。目前市售的诱饵是以寄主果实成熟或发酵的挥发物为基础的，但它们与成熟的果树不具竞争力，也不是铃木毒蛾特有的。这个项目将测试这样的假设，即铃木毒蛾在果蝇中被果实成熟的植物的挥发物吸引是不寻常的，而且相关的挥发物可以用来开发一种比现有诱饵更有吸引力和更具特异性的诱饵。这种诱饵将在世界范围内应用于该害虫的监测和控制。这种创新的方法将英国水果种植者和生产者组织Berry Gardens Growers(制造商Real IPM)和来自两个研究组织East Mling Research和格林威治大学自然资源研究所的科学家聚集在一起。
