Compounds in Metathoracic Glands of Adults and Dorsal Abdominal Glands of Nymphs of the Stink Bugs, Chlorochroa uhleri, C. sayi, and C. ligata (Hemiptera: Pentatomidae)
Hsiao-Yung Ho and Jocelyn G. Millar (2001) The contents of metathoracic glands of adults and dorsal abdominal glands of nymphs of 3 Chlorochroa species, (C. sayi, C. uhleri, and C. ligata) were analyzed. Compounds were identified by gas chromatography (GC) and coupled GC-mass spectrometry, matching retention times and mass spectra with those of authentic samples. Tridecane was the major component in the defensive glands of both adults and nymphs. Other compounds identified include (E)-2-hexenal, (E)-4-oxo-2-hexenal, (E)-2-octenal, (E)- 2-octenyl acetate, (E)-4-oxo-2-octenal, (E)-2-decenal, undecane, dodecane, tetradecane, and pentadecane.
