印度小猫鼬(Herpestes Auropot Tatus)是日本冲绳和大岛县的入侵物种。根除它们的主要战略是使用诱饵诱捕器，由于种群数量减少和本地动物的兼捕，诱饵诱捕器的效率下降。为了解决这些问题，需要猫鼬特有的诱饵。在这项研究中，我们的目标是从小型印度猫鼬的肛囊分泌物中鉴定特定物种和/或性别的化合物。采用热解吸-气相色谱-质谱法分析了雄性和雌性猫鼬肛囊分泌物中的挥发性化合物。除了几种脂肪酸外，2-苯乙醇还被鉴定为一种次要化合物，这种化合物在哺乳动物的分泌物中很少见，但在玫瑰中是主要的气味物质。女性样本比男性样本释放出更高水平的2-苯乙醇。这些发现表明，2-苯乙醇是一种雌性特有的小型印度猫鼬肛囊分泌物的挥发性化合物，它可能是一种有用的猫鼬特有气味诱饵的成分。
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.
