1-Pentadecene Production in Tribolium confusum

Abstract
Odoriferous glands of Tribolium confusum produce volatile compounds which are stored in special reservoirs. Besides the previously reported 2-methyl- and 2-ethyl-1,4-benzoquinones, a new compound, 1-pentadecene, was isolated. The acyclic C14H26O ketone previously reported was not present. 1-Pentadecene is thought to facilitate absorption of the admixed quinones by Tribolium enemies.
