    Venom chemistry of ants in the genusMonomorium (1982)

    Notes: Abstract A comparative analysis of the venomous alkaloids produced by ant species in the subgenusMonomorium of the genusMonomorium has been undertaken. All species produce mixtures of unsymmetricaltrans-2,5-dialkylpyrrolidines, but the proportions of the constituents may vary considerably between species. All alkaloids contain both C6 and C9 side chains which are present as C9-saturated. C6-monounsaturated, and both C6-and C9-monounsaturated dialkylpyrrolidines. The structure of 2-(1-hex-5-enyl)-5-(1-non-8-enyl)pyrrolidine, a previously undescribed alkaloid, was proved by unambiguous synthesis after the location of the double bonds was established by the methoxymercuration-demercuration followed by mass spectrometry. The possible chemotaxonomic significance of the mixtures of venomous alkaloids produced by these species ofMonomorium is discussed.

    Species-specific natural products of adult male leaf-footed bugs (Hemiptera: Heteroptera) (1979)

    Notes: Abstract The 7–8th ventral abdominal gland secretions from 6 adult male leaf-footed bugs,Leptoglossus spp., and a related species,Euthochtha galeator, were chemically analyzed by GC-MS. Of the 11 volatile compounds identified, all but one of the compounds (n-octanol) were aromatic, including compounds with the familiar odors of cherries, vanilla, cinnamon, and roses. The preponderance of aromatics in the adult male ventral abdominal gland secretions contrasts sharply with the aliphatic compounds which comprise the metathoracic gland defensive secretions of adult males and females. Also, the male-specific secretions are species-specific, both qualitatively and quantitatively, whereas the metathoracic gland secretions of Coreoidea are only distinctive at the generic level. It is proposed that males were favored as the emitters of attractive signals by sexual selection, whereas the specificity of the signal is the result of natural selection against hybridization.

    Chemistry and functions of exocrine secretions of the antsTapinoma melanocephalum and T. erraticum (1987)
    Springer
    Journal of chemical ecology 13 (1987), S. 253-263

    ISSN: 1573-1561

    Notes: Abstract Volatile constituents produced by ant workers belonging to the speciesTapinoma melanocephalum andT. erraticum have been analyzed by gas chromatography-mass spectrometry. The pygidial (=anal) gland secretion ofT. melanocephalum is fortified with 6-methyl-5-hepten-2-one and actinidine (the mass spectrum of which is corrected in this paper). An unidentified compound was detected in cephalic extracts. The pygidial gland secretion ofT. erraticum was also dominated by 6-methyl-5-hepten-2-one, in addition to two isomers of iridodial, and iridomyrmecin. The sternal glands contained iridodial and C15-C20 hydrocarbons. Workers ofT. melanocephalum effectively utilize their pygidial gland secretions as an alarm-defense system during aggressive encounters with workers ofSolenopsis geminata. 6-Methyl-5-hepten-2-one is active as a releaser of alarm behavior, and actinidine is repellent to workers ofT. melanocephalum. Cephalic extracts possessed attractant and arrestant properties for workers of this species.
