The tarnished plant bug Lygus lineolaris (Palisot de Beauvois) is considered the most damaging pest of cotton (Gossypium hirsutum L.) in the mid-southern United States. Previous studies have reported the role of different ratios of volatile metathoracic gland components such as hexyl butyrate, (E)-2-hexenyl butyrate and (E)-4-oxo-2-hexenal in eliciting low-level attraction of L. lineolaris. In this study, we tested different visual cues (colored sticky cards) in combination with olfactory cues (pheromone blends) to optimize the attraction and capture of L. lineolaris in the field.
Red-colored sticky cards were more attractive to L. lineolaris adults than white, blue or yellow cards. Red sticky cards combined with blends of three potential pheromone components attracted significantly more L. lineolaris adults than sticky cards without a blend added. Traps baited with a blend of hexyl butyrate, (E)-2-hexenyl butyrate and (E)-4-oxo-2-hexenal in 4:10:7 ratio, respectively, caught a significantly higher number of L. lineolaris than those baited with 10:4:2 or 7:10:4 blends or an unbaited control in the first week of the experiment.
Combining visual cues (red color) with olfactory cues (pheromone blends) significantly increased the capture of L. lineolaris in the field. This device or a future iteration could contribute towards sustainable and environmentally appropriate early-season monitoring and management of L. lineolaris in the field. © 2023 The Authors.

玷污叶蝉（Lygus lineolaris）被认为是美国中南部棉花（Gossypium hirsutum L.）最具破坏性的害虫。先前的研究报告了不同比例的挥发性前胸腺成分，如丁酸己酯、丁酸（E）-2-己烯基和（E）-4-氧代-2-己烯醛，在诱使玷污叶蝉产生低度吸引中的作用。在这项研究中，我们测试了不同的视觉线索（彩色粘性卡片）与嗅觉线索（信息素混合物）相结合，以优化玷污叶蝉在田间的吸引和捕获。
红色粘性卡片比白色、蓝色或黄色卡片对玷污叶蝉成虫更具吸引力。红色粘性卡片与三种潜在信息素成分的混合物结合使用，比不添加混合物的粘性卡片吸引了更多的玷污叶蝉成虫。用丁酸己酯、丁酸（E）-2-己烯基和（E）-4-氧代-2-己烯醛以 4:10:7 的比例混合的诱捕器在实验的第一周内捕获的玷污叶蝉数量明显高于用 10:4:2 或 7:10:4 混合物或未加诱饵的对照诱捕器捕获的玷污叶蝉数量。
将视觉线索（红色）与嗅觉线索（信息素混合物）相结合，显著增加了田间玷污叶蝉的捕获量。这种装置或未来的迭代可以有助于可持续和环境适宜的玷污叶蝉早期田间监测和管理。© 2023 作者。害虫管理科学由 John Wiley & Sons Ltd 代表化学工业协会出版。本文的贡献者是美国政府雇员，他们的工作在美国属于公有领域。
