    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.

    Pentatomid natural products (1978)
    Springer
    Journal of chemical ecology 4 (1978), S. 161-172 
    Details
    ISSN: 1573-1561
    Keywords: Pentatomidae ; Heteroptera ; Asopinae ; sex attractant ; pheromone ; (E)-2-hexenal ; α-terpineol ; benzyl alcohol ; exocrine glands

    Notes: Abstract In addition to the primarily defensive metathoracic glands, adult Pentatomoidea possess a pair of active exocrine glands that open between the III and IV abdominal tergites. In the southern green stink bug,Nezara viridula, and other phytophagous species examined, the glands are small (〈 10 μg secretion/individual) and of approximately equal size in both sexes. In some, but not all, of the predaceous pentatomids (Asopinae), the III-IV dorsal abdominal glands are small in females (〈 10 μg secretion/individual) and extremely large in males (〉500 μg secretion/individual). Using a GC-MS system, the secretion from both males and females ofN. viridula (Pentatominae) was found to contain (E)-2-hexenal, hexanal, 1-hexanol, andn-tridecane. Females contained about three times moren-tridecane than males. The capacious glands ofPodisus maculiventris (Asopinae) males produce (E)-2-hexenal, benzyl alcohol, α-terpineol, linalool, terpinen-4-ol, andcis-piperitol. The composition of the previously unanalyzed secretions from the adult III-IV dorsal abdominal glands is compared and contrasted to that of secretions from the metathoricic gland, and the role of coexisting exocrine glands in adult Heteroptera is discussed.
