    Notes: Abstract Messor lobognathus, an apparent mimic ofPogonomyrmex salinus, shows little chemical resemblance to its exemplar. The mandibular glands ofM. lobognathus gave no volatile compounds. Those ofP. salinus contain chiefly 4-methyl-3-heptanone. Both species contain a mixture of straight-chain alkanes, alkenes, and methyl-branched alkanes in their Dufour glands. Tridecane (64%) is the major substance inM. lobognathus and dodecane (25%) and pentadecane (24%) are the major compounds ofP. salinus. No secretion induced trail-following in either species. A mixture of 9-, 11-, and 13-methylheptacosane formed the largest peak in the chromatograms obtained from the postpharyngeal glands of both species, but otherwise the hydrocarbon mixtures in this gland too were distinct.

    Chemotaxonomic study of undescribed species ofMyrmica ant from Idaho (1991)
    Springer
    Journal of chemical ecology 17 (1991), S. 335-342 
    Details
    ISSN: 1573-1561
    Keywords: Ant ; Myrmica ; Hymenoptera ; Formicidae ; exocrine secretions ; mandibular gland ; Dufour gland ; trail pheromone ; 3-ethyl-2,5-di-methylpyrazine ; bishomofamesene

    Notes: Abstract An undescribed species ofMyrmica collected in Idaho has been shown to have the same substances in its mandibular glands (3-octanol and 3-octanone and related 3-alkanols and 3-alkanones) and in its Dufour gland (linear alkanes, alkenes, and farnesene isomers and homologs) as previously examined European species ofMyrmica. The poison gland contains the trail pheromone 3-ethyl-2,5-dimethylpyrazine, common to allMyrmica species studied so far. The Dufour gland contains large amounts of bishomofarnesene, which easily distinguishes it from some 13 otherMyrmica already known.
