Abstract: The volatiles of carrot flower were absorbed on Tenax TA or Tenax GR and eluted with hexane. Electroantennography (EAG) was used to explore the electrophysiological responses of cotton bollworm (CBW) moths Helicoverpa armigera (Hübner) to the volatiles. The amplitude values of EAG ranged from 0.3 to 0.5mV. The results of combined gas chromatograph-electroantennograph (GC-EAG) and GC-mass spectrum (GC-MS) showed that there were five active components in the volatile oil, in which four compounds were determined as 3-methyl-2-pentanol, myrcene, limonene, ocimene. The behavioral responses of CBW moths to the volatile oil were similar to natural carrot flower. The facts that the carrot flower and it's volatiles were only attactive to 1-2 days old moths, suggested that the carrot flower volatiles are semiochemicals solely associated with the feeding behavior of CBW.
