Drosophila suzukii, commonly known as the spotted wing drosophila (SWD), is an exotic fruit fly from Southeast Asia that was introduced to the temperate regions of North America and Europe in 2008. It attacks a wide variety of fruits and has become a devastating pest of soft-skinned fruit crops. Due to the rapid spread of SWD across the newly invaded continents, fresh fruit markets have a zero-tolerance policy regarding D. suzukii infestation. Specific and efficient D. suzukii detection tools are urgently needed so that farmers can deliver timely management interventions to meet market demands. Since SWD is known to be attracted to damaged and rotting fruits, headspace volatiles from fresh and fermented apple juices were collected and analyzed by gas chromatography–mass spectrometry. Special attention was given to the compounds produced and/or enriched during the fermentation process. After performing a series of laboataory and field tests, we identified a quinary blend, which is more efficient and selective for D. suzukii than the currently standard apple cider vinegar and commercially available SWD lure under field conditions. Identification of SWD attractant will help growers accurately detect D. suzukii adult infestations in orchards, thereby allowing for timely pest management interventions while reducing conventional insecticidal usage to protect our crops, environment, and ecosystem.

从苹果汁中鉴定出有斑点的果蝇果蝇(Drosophila suzukii)的有吸引力的混合物。

铃木果蝇(Drosophila suzukii),通常被称为斑果蝇(SWD),是一种来自东南亚的奇异果蝇,于2008年被引入北美和欧洲的温带地区。它攻击各种各样的水果,并成为毁灭性害虫。皮肤柔软的水果作物。由于社署在新近入侵的大陆迅速蔓延,新鲜水果市场对铃木蝇的侵扰实行零容忍政策。铃木D.高效迫切需要检测工具,以便农民能够及时提供管理干预措施,以满足市场需求。由于已知SWD会被损坏和腐烂的水果吸引,因此收集了新鲜和发酵的苹果汁中的顶空挥发物,并通过气相色谱-质谱法进行了分析。对发酵过程中产生和/或富集的化合物给予了特别关注。在进行了一系列的实验研究和野外试验之后,我们确定了一种五合混合物,它比传统的苹果醋和市售的SWD在野外条件下对铃木蝇更有效和更具选择性。鉴定SWD引诱剂将帮助种植者准确检测铃木D. 果园成虫成虫,因此可以及时进行虫害管理干预,同时减少常规杀虫剂的使用,以保护我们的作物,环境和生态系统。
