Capillary gas chromatography indicated the presence of ( Z )‐7‐dodecenyl alcohol and ( Z )‐7‐dodecenyl acetate in the abdominal tip extracts of female Cornutiplusia circumflexa (L.) (Lepidoptera: Noctuidae: Plusiinae) moths. Gas chromatography combined with mass spectrometry and dimethyl disulfide derivatization confirmed the structure of these two principal pheromone components. In a flight‐tunnel bioassay, a 5:1 blend of alcohol and acetate elicited the complete courtship sequence by males. The response was comparable to that evoked by a live virgin female, but males spent significantly longer time at calling females than at the synthetic source. The 5:1 blend was also attractive to male C. circumflexa in the field, as indicated by catches in traps baited with this mixture. ( Z )‐7‐dodecenyl alcohol alone was slightly attractive whereas ( Z )‐7‐dodecenyl acetate alone was completely inactive. C. circumflexa is the first reported Plusiinae species which utilizes ( Z )‐7‐dodecenyl alcohol as the major pheromone component.
