Summary
A 6-step method is described convenient for 16 000-fold enrichment of a scent-trail pheromone of the termite speciesZootermopsis nevadensis Hagen. By means of a combined gas chromatography-mass spectrometry arrangement n-caproic acid and 3 other compounds of biological activity (molecular weights between 152 and 238) were identified as components of the pheromone. The fragmentation pattern and chemical data indicate that one of the components is an ester-compound. In addition, data of some normal, branched and unsaturated hydrocarbons are obtained, which serve as carriers of the pheromone.
