| Abstract: | The Dufour gland secretion and cuticle lipids of foundresses of Polistes dominulus have been chemically analysed. The gland secretion (analysed for the first time in a polistine species) contains a complex mixture of hydrocarbons, which are the same as those found on the cuticle. The cuticular hydrocarbon mixture and gland secretion differ, however, in the proportions of components: in the first, linear hydrocarbons are more abundant, while in the second we found a higher quantity of dimethylalkanes. Multivariate statistical analysis has shown that foundresses belonging to different colonies are distinguished on the basis of both the composition of their Dufour gland secretion and cuticular hydrocarbon mixture. Branched hydrocarbons seem to be particularly important in distinguishing females according to their colony. We suggest that the Dufour gland may contribute substances to form the hydrocarbon layer on the cuticle. |
