Abstract

An abdominal tip extract of female bertha armyworm moths, Mamestra configurata (Walker), was found to contain two sex pheromone components. One corresponded to (Z)-11-hexadecen-1-ol acetate, previously identified from this source, and the other to a tetradecen-1-ol acetate, identified by gas chromatography – mass spectrometry. Data obtained from the EAG profile of isomeric tetradecen-1-ol acetates indicated the active component to be (Z)-9-tetradecen-1-ol acetate. Neither of these two acetates was by itself attractive to males in field tests; however, mixtures were attractive, with the best attraction occurring with a C16:C14 acetate ratio of about 19:1.
