A detailed comparative analysis of the exocrine chemistry of nine Bruneian Camponotus species in the cylindricus complex is reported. Workers of these species are known to have hypertrophied mandibular glands and release their glandular contents suicidally from the head by rupturing the intersegmental membrane of the gaster. All of the species produce mixtures of polyacetate-derived aromatics, including hydroxyacetophenones, which display pH-dependent color changes, and aliphatic hydrocarbons and alcohols. In addition, three species contained (6R)-2,6-dimethyl-(2E)-octen-1,8-dioic acid (9) or (3S)-8-hydroxycitro-nellic acid (10a), previously unreported from insects. These compounds were characterized from their spectral data, and confirmed by comparison with synthetic samples. The allomonal role of these compounds is based on numerous field observations, and their chemotaxonomic value is presented.
本文报道了对圆柱蚁属复合体中9种文莱弓背蚁外分泌化学的详细比较分析。已知这些物种的工蚁具有肥大的下颌腺，并通过破坏腹部的节间膜从头部自毁性地释放其腺体分泌物。所有物种都产生源自聚乙酸酯的芳烃混合物，包括羟基苯乙酮，其显示出pH依赖性颜色变化，以及脂肪族烃和醇类。此外，有三个物种含有（6R）-2,6-二甲基-（2E）-辛烯-1,8-二酸（9）或（3S）-8-羟基香茅酸（10a），这两种化合物此前从未在昆虫中报道过。这些化合物通过其光谱数据进行表征，并与合成样品比较进行确认。基于大量野外观察，阐述了这些化合物的异源信息素作用及其化学分类学价值。
