    Notes: Abstract Cephalic extracts of two unrelated species of ants,Leptogenys processionalis andPogonomyrmex rugosus, have been found to contain 2-phenylpropenal and 2-phenyl-2-butenal, while two other species related to the first,L. chinensis andL. kitteli, lacked either.L. kitteli also produced a tetrasubstituted pyrazine found previously only in two New Zealand ants in the genusMesoponera. The chemical reactivity of the phenylalkenals suggests their function in repelling attack by predators.

    Eclectic chemisociality of the honeybee (1988)
    Springer
    Journal of chemical ecology 14 (1988), S. 2099-2107

    Notes: Abstract A dazzling variety of honeybee behaviors are triggered by pheromones produced by disparate exocrine glands. A multiplicity of chemical releasers of social behavior has been demonstrated to regulate a diversity of societal interactions, and many of these compounds are synthesized with great caste specificity. Recent investigations have resulted in the identification of a host of new compounds that are products of either worker or queen honeybees. This report fractionates these newly identified exocrine products according to their glandular proveniences and focuses on both the structural and behavioral eclecticism that characterizes these chemical signaling agents.

    Volatile compounds from ponerine ants in the genusMesoponera (1984)
    Springer
    Journal of chemical ecology 10 (1984), S. 651-665 
    Details
    ISSN: 1573-1561
    Keywords: Hymenoptera ; Formicidae ; Mesoponera ; ants ; ponerine ants ; secondary and tertiary aliphatic amines ; formamides ; acetamides ; isovaleramides ; 2,6-dimethyl-3-isopentylpyrazine ; aliphatic aldehydes and acids ; phenylacetic acid

    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract Volatile constituents have been characterized from two species of ponerine ants in the genusMesoponera. 2,5-Dimethyl-3-isopentyl-pyrazine has been identified from cephalic extracts ofM. castanea andM. castaneicolor, by gas chromatography-mass spectrometry. Combined gasters and thoraces of both species are also characterized by the presence of nonanal, nonanoic acid, isovaleric acid, phenylacetic acid, and undecanal, as well as a series of aliphatic amines and amides.N-Isoamylnonylamine was a major constituent that was accompanied byN-isoamylnonenylamine,N,N-diisoamylnonylamine,N-acetyl nonylamine,N-formyl isoamylnonylamine,N-isovaleroyl nonylamine, and several other secondary and tertiary amines. The possible significance of the amines and amides as idiosyncratic natural products ofMesoponera species is discussed.
