We have been able to discriminate different castes and sexes of ants in the same colony by measuring cuticular hydrocarbon levels with Fourier transform infrared photoacoustic spectroscopy, compared by canonical discriminant function analysis. We have now applied this methodology to various colonies of two species of ants of the genus Ectatomma in the Brazilian Cerrado. There were clear interspecific differences in cuticular hydrocarbons of these ants, with a small intraspecific variation. The differences between colonies were greater in E. brunneum than in E. vizottoi. Genetic differences among the colonies and species were well estimated by Fourier transform infrared photoacoustic spectroscopy and statistical analyses.
通过傅里叶变换红外光声光谱法测量表皮碳氢化合物水平，并经典型判别函数分析比较，我们已能够区分同一蚁群中不同种姓和性别的蚂蚁。我们现在已将此方法应用于巴西塞拉多地区两种埃氏蚁属蚂蚁的各个蚁群。这些蚂蚁的表皮碳氢化合物存在明显的种间差异，种内变异较小。褐埃氏蚁蚁群之间的差异比维氏埃氏蚁的更大。傅里叶变换红外光声光谱法和统计分析很好地估计了蚁群和物种之间的遗传差异。
