Summary.

Dufour glands of Paratrechina longicornis were analyzed chemically using GC-MS techniques. The glands contained twelve alkanes between C9 and C20 chain length with undecane and tridecane as the main components, six alkenes (1- and 4-undecene, 1-, 4-, and 6- tridecene, and heptadecadiene), two alkyl formates (C11 and C13), and saturated and polyunsaturated acids. Many of the alkanes and alkenes were behaviorally active causing a short lasting attraction of ants with different intensity. Detection of the major gland compound undecane in recruitment trails by in vivo SPME sampling provided evidence for its use as a recruitment pheromone. Both poison gland (formic acid) and Dufour gland (undecane) contents were detected on SPME fibers which had been attacked by the ants.
