The small Indian mongoose (Herpestes auropunctatus) is an invasive species in Okinawa and Amami-Oshima, Japan. Major strategies for their eradication have been the use of baited traps, which suffer from decreasing efficiency with declining populations and the bycatch of native animals. To address these concerns, mongoose-specific lures are required. In this study, we aimed to identify species- and/or sex-specific compounds from anal sac secretions of small Indian mongooses. Volatile compounds emitted from male and female mongoose anal sac secretions were analyzed by thermal desorption-gas chromatography-mass spectrometry. In addition to several fatty acids, 2-phenylethanol was identified as a minor compound, which is uncommon in mammalian secretions but a dominant odorant in roses. Female samples emitted higher levels of 2-phenylethanol than male samples did. These findings indicate that 2-phenylethanol is a female-specific volatile compound of anal sac secretions in small Indian mongooses, and it may be useful as an ingredient of mongoose-specific scent lures.
小印度猫鼬（Herpestes auropunctatus）是日本冲绳和奄美大岛的入侵物种。根除它们的主要策略是使用诱饵陷阱，但随着种群数量的减少以及本土动物的误捕，这种方法的效率逐渐降低。为了解决这些问题，需要特定于猫鼬的诱饵。在本研究中，我们旨在从小印度猫鼬的肛门腺分泌物中鉴定出物种和/或性别特异性化合物。通过热解吸-气相色谱-质谱联用仪分析了雄性和雌性猫鼬肛门腺分泌物释放的挥发性化合物。除了几种脂肪酸外，还鉴定出2-苯乙醇为次要化合物，它在哺乳动物分泌物中并不常见，但却是玫瑰中的主要气味成分。雌性样本中2-苯乙醇的含量高于雄性样本。这些发现表明，2-苯乙醇是小印度猫鼬肛门腺分泌物中的一种雌性特异性挥发性化合物，它可能作为猫鼬特异性气味诱饵的一种成分。
