Carob moth, Ectomyelois ceratoniae Zeller (Lepidoptera: Pyralidae), is an important pest of some fresh and dried fruits in the world. (Date, Pistachio, Almond, Fig, Citrus and Apple). it is the key pest of pomegranate fruit in Iran. Habrobracon hebetor (Say) (Hym. Braconidae) is a cosmopolitan ectoparasitoid that attacks the larva of several Pyralid species including carob moth. Foraging behavior of natural enemies rely on a plethora of semiochemicals, released from its host, using for host location, recognition and acceptance. Semiochemicals play an important role in host finding by parasitoids. Behavioral response of the parasitoid H.hebetor to volatile compounds derived from its host, carob moth, ، was investigated in Y-tube olfactometer. The study results showed that the last instar larvae of carob moth and its faeces were attractive for females and males of H. hebetor. So the volatile components of these two treatments were extracted using the solid phase microextraction (SPME) method. Chemical analyses of the extracts were performed by Gas chromatography–mass spectrometry (GC-MS). In total 40 components of last instar larvae and 45 components of its faeces were identified. The six compounds including Acetonitrile, dl-Limonene, Cyclopentadecanone, 2-hydroxy- tetradecane, Nonadecane and Hexadecane, were identified in two treatments, and they are probably specific compounds for faeces. Also, according to the results of other studies nonanal and 1-pentadecene are the major components of faeces, attractive for the parasitoid. Identification of the active components on foraging behavior of this natural enemy can play an important role on their application in Integrated Pest Management (IPM).
