spp. soldier defensive secretion has a toxic and repellent effect against predators. Chemical profile characterization of this secretion is an interesting tool to differentiate similar termite species. This study aimed to determine defensive secretion composition of spp. soldier and to apply chemotaxonomy tool for the unambiguous species identification. Fifteen volatile compounds were identified by gas chromatography-mass spectrometry. Multivariate analysis classified populations into three groups. Principal component (PCA), axis 1, was able to separate two groups: group I, colonies 1 and 2 ( and group II, colony 3 (). Therefore, determination of defensive chemical secretion profile proved to be very useful in termite chemotaxonomy, since it was able to differentiate morphologically similar specimens.
种兵蚁的防御分泌物对捕食者具有毒性和驱避作用。这种分泌物的化学特征分析是区分相似白蚁物种的有趣工具。本研究旨在确定种兵蚁的防御分泌物成分，并应用化学分类学工具进行明确的物种鉴定。通过气相色谱-质谱联用仪鉴定出 15 种挥发性化合物。多元分析将种群分为三组。主成分（PCA），轴 1，能够将两组分开：组 I，殖民地 1 和 2（）和组 II，殖民地 3（）。因此，防御性化学分泌物特征的测定在白蚁化学分类学中非常有用，因为它能够区分形态相似的标本。
