    Chemistry of venom alkaloids in the ant genusMegalomyrmex (1991)
    Springer
    Journal of chemical ecology 17 (1991), S. 1897-1908 
    Details
    ISSN: 1573-1561
    Keywords: Megalomyrmex ; Hymenoptera ; Formicidae ; venom ; alkaloids ; ants ; trans-2,5-dialkylpyrrolidine ; 3,5-dialkylpyrrolizidine ; Hofmann degradation

    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract Chemical analyses of three species in the Neotropical ant genusMegalomyrmex have identified this taxon as the third myrmicine genus to produce alkaloids as major venom products. Workers ofM. leoninus and workers and ergatoids ofM. goeldii produce one or more of fourtrans-2,5-dialkylpyrrolidines previously identified in other myrmicine genera.M. modestus, on the other hand, is distinctive in producing the novel alkaloid (5E,8E)-3-butyl-5-hexylpyrrolizidine (5d), whose structure was established using a micro-Hofmann degradation sequence. The relationship ofMegalomyrmex to other alkaloid-producing ant genera is discussed along with the possible chemotaxonomic significance of the analyzed species when viewed in terms of the recognized species groups in this genus.

    Honeybee nestmate recognition: Effects of queen fecal pheromones (1992)
    Springer
    Journal of chemical ecology 18 (1992), S. 1633-1640 
    Details
    ISSN: 1573-1561
    Keywords: Apis mellifera ; honeybee ; Hymenoptera ; Apidae ; queen ; fecal ; pheromones ; esters ; kin recognition
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract Previous work has shown that queen honeybees,Apis mellifera, produce waxy esters composed of 8–14 carbon acids and 6–14 carbon alcohols in their feces. We tested these esters for effects on nestmate recognition; 11 of the 12 esters tested significantly modified the recognition characteristics of worker honeybees. Pairwise tests showed that workers can discriminate between at least some pairs of queen esters and that workers can discriminate between a queen ester and hexadecane (another known nestmate recognition cue). These results suggest that a queen may use the esters to enable workers to recognize her or to scent-mark her colony.
