Our study was conducted on the feeding behaviour of the loboptera angulata species collected in the Chelia cedar (Aures, Algeria), where we tested with a bidirectional olfactometer the attractiveness of forty individuals (20 larvae, 20 adults) of thise species against the three hexanic extracts of fresh cedar leaves, aleppo pine and green oak. The study showed that the adults of L, angulata were significantly more attracted to fragrant fresh Cedar and Aleppo Pine leaves with a preference for cedar extract and they take less time to detect odour regardless of the type of extract (Aleppo Pine, Cedar or Green Oak) compared to larvae Where were not significantly attracted by any odorous extract of the leaves used and they take a much longer time to locate the odorous source from the fragrant extracts.
