Summary

We investigated cuticular hydrocarbons and fatty acids of workers and queens from two ant species, Leptothorax acervorum and L. gredleri. Cuticular compounds were extracted from single ants by solvent extraction, solid sampling, and solid phase microextraction (SPME) with two different polydimethylsiloxane (PDMS) fibers and analyzed using GC and GC-MS. All three methods gave similar results, documenting that SPME can be applied to very small, live ants (body size appr. 3 mm). The hydrocarbon mixtures consisted mostly of branched and unbranched alkanes and alkenes within the range of C25 to C33. Dufour glands of both species contained a blend of hydrocarbons different from those found on the cuticle. In addition, terpenoids, especially tetramorenes were present in the Dufour gland contents. In a principal components analysis based on the relative proportions of cuticular compounds, most nestmate workers clustered in four groups corresponding to the original four investigated colonies. Queens and workers differed significantly in their chemical profiles, suggesting that the two castes bear specific labels.
