    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.

    (S)-2-Methyl-1-hexanol, characteristic mandibular gland substance of ants of theCataglyphis bicolor group (1996)

    Notes: Summary In all the species of theCataglyphis bicolor group examined yet, i.e.C. bicolor, C. diehli, C. isis, C. nodus, andC. viaticus, 2-methyl-1-hexanol is the characteristic substance and almost the only substance found in the mandibular glands. Its chirality has been determined inC. bicolor and shown to be exclusively (S)-2-methyl-1-hexanol.

    Dufour gland contents of three species ofMyrmecia (Hymenoptera: Formicidae), primitive ants of australia (1989)
    Springer
    Journal of chemical ecology 15 (1989), S. 2191-2205

    ISSN: 1573-1561
    Keywords: Ant ; Dufour gland ; Myrmecia ; Hymenoptera ; Formicidae ; hydrocarbons ; acetates ; eicosenal ; chemotaxonomy

    Topics: Biology , Chemistry and Pharmacology
    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.

    Contents of dufour glands of workers of three species ofTetramorium (Hymenoptera: Formicidae) (1986)

    Notes: Abstract The Dufour glands of worker ants ofTetramorium caespitum, and the morphologically similarT. impurum are filled with similar, but species-specific mixtures of linear hydrocarbons and three homologous sesquiterpene corhpounds. Glands of workers ofT. caespitum contain, on average, 70 ng of oil containing C13 to C17 linear hydrocarbons withn-pentadecane (64%) and a mixture of pentadecenes (14%) as major components.T. impurum glands are smaller and contain an average of 40 ng of the same mixture but withn-pentadecane (49%) and a sesquiterpenoid compound (19%) the major components. Two isomeric pentadecenes, (Z)-6-pentadecene and (Z)-7-pentadecene are present in both species.T. semilaeve workers contain on average only 30 ng of a simple mixture of hydrocarbons with pentadecane contributing more than 90% of the total.

    (Z)-11-Eicosen-1-ol, a Major Component of Apis cerana Venom (1997)
    Springer
    Journal of chemical ecology 23 (1997), S. 1929-1939

    ISSN: 1573-1561
    Keywords: (Z)-11-Eicosen-1-ol ; octadecanol ; eicosanol ; docosenol ; alarm pheromone ; venom ; Apis cerana ; Apis koschevnikovi ; Apis dorsata ; Apidae ; Hymenoptera

    Notes: Abstract The unusual venom of Apis cerana contains large oily droplets within an otherwise aqueous secretion. Chemical analysis (GC-MS) revealed that the venom oil consists of (Z)-11-eicosen-1-ol (81.2%), other linear alcohols (7.7%), and linear hydrocarbons (11.1%). The eicosenol is present in extremely large quantities, averaging over 250 μg per insect, and is absent, or present in small quantities, in other parts of the sting apparatus. An investigation of the site of eicosenol storage in A. mellifera showed it to be absent from the venom and to be associated with the setose area where the more volatile components of the alarm pheromone are stored, as previously shown by others. A third honeybee species, A. dorsata, does not to contain the alcohol. The function of eicosenol in A. cerana in not clear, but may serve to mark stung intruders with pheromone or to attract foragers to marked floral resources.

    Notes: Abstract The trail pheromone ofAcromyrmex subterraneus subterraneus consists simply of the heterocyclic ester methyl 4-methylpyrrole-2-carboxylate in the venom reservoir of workers at about 1.2 ng/ant. No pyrazines were detected, and no enhancement of trail-following was observed when pyrazines were added to the pyrrole compound.
