Phyllotreta striolata (Fabricius) is an important pest of Brassicaceae in Southeast Asia and North America. Using scanning electron microscopy, we observed the external structure, number, and distribution of the antennal sensilla in P. striolata females to discuss the putative function of these sensilla in host location and oviposition behaviors. The antenna of female P. striolata is filiform, composed of a scape, a pedicel, and a flagellum with 9 flagellomeres. Five types of sensilla were identified, including sensilla cheaetica, sensilla trichodea, Böhm bristles, sensilla auricillica, and sensilla basiconica (five subtypes, SB1-SB2). External structure and distribution of antennal sensilla are compared with data from other insect species. In addition, we discuss the possible functions of antennal sensilla based on their characteristics.
黄曲条跳甲（Phyllotreta striolata (Fabricius)）是东南亚和北美的十字花科重要害虫。我们利用扫描电子显微镜观察了黄曲条跳甲雌虫触角感器的外部结构、数量和分布，以探讨这些感器在寄主定位和产卵行为中的假定功能。黄曲条跳甲雌虫的触角呈丝状，由柄节、梗节和具9个鞭节的鞭节组成。鉴定出了五种类型的感器，包括毛形感器、刺形感器、Böhm氏鬃毛、耳形感器和锥形感器（五个亚型，SB1 - SB2）。将触角感器的外部结构和分布与其他昆虫物种的数据进行了比较。此外，我们根据触角感器的特征讨论了其可能的功能。
