<i>trans</i> -2-Dodecenal and 2-Methyl-1,4-Quinone Produced by a Millipede

Abstract

An aldehyde, trans-2-dodecenal, heretofore known only from plants, has been identified in the defensive secretion of the spiroboloid millipede Rhinocricus insulatus. A second component, 2-methyl-1,4-quinone, was previously known from the secretion of related millipedes.
