15AGRITECHCAT4: Early attractants for the major new fruit pest, Drosophila suzukii; a 'super lure'

斑点翅果蝇，又称苏氏果蝇，起源于远东，但最近作为一种入侵害虫出现在美国和欧洲。与大多数其他种类的果蝇不同，它们只攻击成熟和过熟的水果，在商业环境中作为害虫的经济重要性很小，铃木夜蛾可以攻击成熟的水果，并有可能成为欧洲和美国最具破坏性的软果和核果害虫。雌性在收获前在果实中产卵，幼虫在果实中觅食，导致果实质量迅速退化，使其无法销售。目前商业上可用的诱饵是基于宿主水果的成熟或发酵挥发物，但它们与成熟的水果作物没有竞争力，也不是针对铃木夜蛾的。该项目将验证这样一种假设，即在果蝇中，铃木夜蛾是不寻常的，它会被成熟果实植物的挥发物吸引，而这种挥发物可以用来开发一种比现有的诱饵更有吸引力、对铃木夜蛾更有针对性的诱饵。这种诱饵将在世界范围内用于监测和控制这种害虫。这种创新的方法汇集了英国水果种植者和生产商组织，浆果花园种植者，制造商，Real IPM，以及来自两个研究机构，东马林研究所和格林威治大学自然资源研究所的科学家。

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.
