Abstract Drosophila suzukii (Matsumura) and Zaprionus indianus (Gupta) (Diptera: Drosophilidae) are invasive pests of economic importance worldwide. D. suzukii attacks soft-skinned fruits in Asia, Europe, North and South America. Also, Z. indianus has recently been found in Asia, Europe, and America attacking orange, peach, and fig fruits while they are still on trees. Both flies have been captured in berry crops in Michoacan, Mexico. D. suzukii is known to use visual and chemical cues to search for host plants. For this reason, these cues have been used in developing traps and attractants to trap the insect in berry crops. In this study, color contrasts not yet evaluated were evaluated to investigate the possibility of enhancing attraction and capture of D. suzukii and Z. indianus in a single trap design. All traps were baited with a commercial Z-kinol attractant in a blackberry crop. In the two seasons evaluated, the same effect was observed in the capture of both fly species. The transparent traps (without color) that contained a yellow card inside as a visual stimulus was the one that captured the most individuals of both drosophilids. The results obtained will be useful for the massive monitoring and trapping of D. suzukii and Z. indianus populations in Mexico.

不是诱捕器的颜色，而是作为诱捕器内部近距离刺激物的颜色增加了浆果作物中的铃木果蝇和印度刺眼蝇（双翅目：果蝇科）的捕获

摘要 Drosophila suzukii (Matsumura) 和 Zaprionus indianus (Gupta)（双翅目：果蝇科）是世界范围内具有重要经济意义的入侵害虫。D. suzukii 攻击亚洲、欧洲、北美和南美的软皮水果。此外，最近在亚洲、欧洲和美洲发现了 Z. indianus 攻击仍在树上的橙子、桃子和无花果果实。这两种苍蝇都在墨西哥米却肯州的浆果作物中被捕获。已知 D. suzukii 使用视觉和化学线索来寻找寄主植物。出于这个原因，这些线索已被用于开发诱捕器和引诱剂，以在浆果作物中诱捕昆虫。在这项研究中，对尚未评估的颜色对比进行了评估，以研究在单个陷阱设计中增强对 D. suzukii 和 Z. indianus 的吸引和捕获的可能性。所有诱捕器都用黑莓作物中的商业 Z-kinol 引诱剂作为诱饵。在评估的两个季节中，在捕获两种苍蝇方面观察到了相同的效果。里面有一张黄牌作为视觉刺激的透明陷阱（没有颜色）是捕获两种果蝇中最多个体的陷阱。获得的结果将有助于在墨西哥大规模监测和诱捕 D. suzukii 和 Z. indianus 种群。
