    Notes: Summary The Dufour gland of the primitive Australian antNothomyrmecia macrops contains microgram quantities in total of linear alkanes and alkenes from C13 to C30 with heptadecene the major component (66%). In all, 50 substances, including methyl-branched hydrocarbons, aldehydes and acetates, α-farnesene and α-springene in low nanogram amounts, were identified by gas chromatography-mass spectrometry.

    Notes: Summary Comparison of the contents of the postpharyngeal gland and cuticular hydrocarbons of five species of ant have shown them to contain the same compounds and to be characteristic of the species. For four species (Formica selysi, Camponotus lateralis, Camponotus vagus andManica rubida), quantitative similarity was very close, but more divergent in the fifth (Myrmica rubra). Glands and cuticle ofM. rubra queens were shown to be closely similar to those of workers, except the glands of queens are larger, but the cuticle of larvae was different from that of adult cuticle and postpharyngeal glands.

    Contents of Dufour glands in some formicine ants: queens and workers of Camponotus aethiops and a re-examination of Lasius fuliginosus (1988)

    Description / Table of Contents: Résumé Les sécrétions des glandes de Dufour sont toutes semblables et comprennent, chez les reines et les ouvrières de C. aethiops, une chaîne linéaire d'hydrocarbures de C10 à C15, avec C11 comme constituant principal. Les différences entre les castes se traduisent chez la reine, par une teneur totale en sécrétions plus faible et l'existence de C15 uniquement sous forme de traces. Chez L. fuliginosus, la sécrétion de la glande de Dufour comprend une série de chaînes linéaires d'hydrocarbures (C10−C17) avec l'undécane comme constituant principal, et une série de 2-alkanones allant de C13 à C19.
    Notes: Abstract The Dufour gland secretions of both virgin queens and workers of Camponotus aethiops are similar and consist of straight chain hydrocarbons ranging from C10−C15 with C11 the major compound. The difference between the two castes is that C15 appears only as a trace in queens, and the total amount of secretion is smaller in queens than in workers. In Lasius fuliginosus, the Dufour gland secretion contains a series of straight chain hydrocarbons (C10−C17) with undecane the major compound, and a series of 2-alkanones ranging from C13 to C19.

    Dufour gland contents of three species ofMyrmecia (Hymenoptera: Formicidae), primitive ants of australia (1989)

    Notes: Abstract Chemical investigation of the Dufour gland contents of three species ofMyrmecia by GC and GC-MS showed thatM. gulosa andM. nigriceps contain predominantly linear hydrocarbons, whereasM. pilosula contains acetates, aldehydes, and propionates. The major components ofM. gulosa andM. nigriceps are (Z)-8-heptadecene, pentadecane, and heptadecane. Their chemical profiles are similar to each other and to that ofNothomyrmecia macrops, the most primitive living ant, placed by itself in a separate subfamily. The major components ofM. pilosula are hexadecyl acetate, (Z)-9-octadecenyl acetate, (Z)-11-eicosenyl acetate, and (Z)-11-eicosenal. Some geographical variation was observed in the relative proportions of the components. The chemotaxonomic significance for the primitive Australian ant subfamilies Myrmeciinae and Nothomyrmeciinae is considered. The possibility is discussed that 11-eicosenal or geranylcitronellol, minor components of the Dufour gland secretion ofM. gulosa, may be responsible for the aggressive behavior released by the natural stinging secretions.
