| Abstract: | "Many species of tenebrionids produce and secrete a defensive volatile blend containing mainly benzoquinones and alkenes. In this study we characterized the volatile organic compounds (VOC) of the beetle Ulomoides dermestoides (Coleoptera: Tenebrionidae). Solid phase microextraction (SPME) coupled to capillary gas chromatography-mass spectrometry (CGC-MS) analysis was used to identify methyl-1,4-benzoquinone (MBQ), ethyl-1,4-benzoquinone (EBQ), 1-tridecene (C(13:1)), and 1-pentadecene (C(15:1)), representing more than 90% of the volatile blend. We also used CGC-MS to analyze the epicuticular hydrocarbons of U. dermestoides. Saturated, unsaturated, and branched structures with chain lengths ranging from 13 to 43 carbons were detected. n-pentacosane (C(25:0)) and 9,11-pentacosadiene (9,11-C(25:2)) were the most abundant components, representing more than 40% of the cuticular hydrocarbons" |
