Abstract

Whole-body volatiles from males of the cryptic multimammate mouse speciesMastomys natalensis andM. coucha were analyzed by dynamic solvent effect sampling and capillary gas chromatography. One compound, 3-nonene-2-one, was always present, sometimes as the major component, in volatiles fromM. coucha and absent, or present only at low levels, in volatiles fromM. natalensis. The mean ±SD of the 3-nonen-2-one peak area forM. coucha was 8599 ±9630 and forM. natalensis 148 ±486. Chromatographic analysis was more reliable in identifying a male's species than were a female's in a two-choice olfactorium.

摘要

采用动态溶剂效应采样和毛细管气相色谱法分析了隐密多齿鼠种 Mastomys natalensis 和 Mastomys coucha 雄性个体的全身挥发物。有一个化合物 3-壬烯-2-酮总是存在于 Mastomys coucha 的挥发物中，有时是主要成分，而在 Mastomys natalensis 的挥发物中则不存在，或者只存在于低水平。Mastomys coucha 的 3-壬烯-2-酮峰面积平均值±标准差为 8599±9630，而 Mastomys natalensis 的峰面积平均值±标准差为 148±486。与在二选一嗅觉仪中使用雌性个体相比，色谱分析在识别雄性个体的物种方面更可靠。
