Abstract Zaprionus indianus Gupta (Diptera: Drosophilidae) is a successful invasive drosophilid that is currently impacting fig production in Mexico and Brazil. Very few studies have examined the improvement of trapping strategies for this pest. Here, we compared visual responses of Z. indianus to different colors and olfactory cues. Orange and brown colored traps were among the most attractive in choice and no-choice tests, with violet and white being the least attractive colors. Orange traps with brown circles around the access holes were more attractive than uniformly orange traps. Apple cider vinegar was significantly more attractive to adults than sugar cane vinegar or grape juice but was not significantly more attractive than white wine and red wine vinegars. Captures of Z. indianus in apple cider vinegar-baited traps were not improved by the addition of grape, pineapple or apple juices, or when compared against a sucrose solution or grape juice fermented with Saccharomyces cerevisiae, or grape juice fermented with Candida tropicalis. Pairwise comparisons of Z. indianus attraction to S. cerevisiae and C. tropicalis indicated a high dependence on the growth media used. Orange traps with brown circles baited with apple cider vinegar may prove useful for monitoring this pest under field conditions.

用于监测 Zaprionus indianus（双翅目：果蝇科）的诱捕颜色和醋、酵母和果汁诱饵组合的实验室评估

摘要 Zaprionus indianus Gupta（双翅目：果蝇科）是一种成功的入侵果蝇，目前正在影响墨西哥和巴西的无花果生产。很少有研究检查过这种害虫诱捕策略的改进。在这里，我们比较了 Z. indianus 对不同颜色和嗅觉线索的视觉反应。橙色和棕色陷阱在选择和非选择测试中最具吸引力，紫色和白色是最不吸引人的颜色。入口孔周围带有棕色圆圈的橙色陷阱比统一的橙色陷阱更具吸引力。苹果醋对成年人的吸引力明显高于甘蔗醋或葡萄汁，但并不比白葡萄酒和红酒醋更具吸引力。Z 的捕获。通过添加葡萄、菠萝或苹果汁，或者与蔗糖溶液或用酿酒酵母发酵的葡萄汁或用热带念珠菌发酵的葡萄汁相比，苹果醋诱饵诱捕器中的 indianus 没有得到改善。Z. indianus 对 S. cerevisiae 和 C.tropicals 的吸引力的成对比较表明对所使用的生长培养基的高度依赖。用苹果醋作为诱饵，带有棕色圆圈的橙色陷阱可用于在田间条件下监测这种害虫。tropicalis 表明高度依赖于所使用的生长培养基。用苹果醋作为诱饵，带有棕色圆圈的橙色陷阱可用于在田间条件下监测这种害虫。tropicalis 表明高度依赖于所使用的生长培养基。用苹果醋作为诱饵，带有棕色圆圈的橙色陷阱可用于在田间条件下监测这种害虫。
