The airborne volatiles emitted from individual female Heliothis zea (Boddie) pheromone glands were collected by adsorption onto glass wool, analyzed, and quantified on an SP-2330 capillary GLC column. All of the compounds previously reported from gland washes, 16:Ald, Z7-16:Ald, Z9-16:Ald and Z11-16:Ald, were found in the volatile emissions. The forcibly extruded female H. zea pheromone glands exhibited a periodicity of pheromone release: maximal pheromone emission occurred between 1 and 2 h and the minimal pheromone emission between 5 and 21 h after the onset of scotophase.
