Onion maggot (Delia antiqua) is an economically important pest of Allium crops in temperate regions throughout the world. Management of this pest is necessary to achieve economic returns and depends on insecticide regimes and cultural management. Current cultural management especially altering planting date, field location and crop rotation depend on monitoring. We evaluated the effect of shape, size, colour and chemical attractants on trap catch of field populations of adult D. antiqua flies in upstate New York. White, large diameter, spherical traps in conjunction with Delia Lure attractant performed the best in attracting and catching D. antiqua adults. These results suggest an improved means of attracting and capturing D. antiqua populations which could be useful in monitoring efforts and development of attract and kill strategies for pest control.

洋葱蛆（Delia antiqua）通过改良诱捕技术进行实地监测

洋葱蛆（Delia antiqua）是全球温带地区葱属作物的重要经济害虫。这种害虫的管理对于实现经济回报是必要的，并取决于杀虫剂制度和文化管理。当前的文化管理，尤其是改变种植日期、田间位置和轮作取决于监测。我们评估了形状、大小、颜色和化学引诱剂对纽约州北部成年 D. antiqua 苍蝇野外种群诱捕捕获的影响。白色、大直径、球形诱捕器与 Delia Lure 引诱剂一起在吸引和捕捉 D. antiqua 成虫方面表现最佳。这些结果表明吸引和捕获 D 的改进方法。
