[The sex-trapping of Sterrha biselata (Hufn.) (Lepidoptera Geometridae, Sterrhinae) by acetoxy-1 dodecadiens-7 E, 9Z, the sex pheromone of Lobesia botrana (Schiff.) (Lepidoptera Tortricidae, Olethreutinae)].

7E, 9Z dodecadienyl acetate, a sex-heromone for Lobesia botrana, is selectively attractive, in vineyards, for males of this species. By testing this compound in woods and orchards, we have found that it was also selectively attractive for males of a geometrid moth; Sterrha biselata. This is one of the first examples where a definite chemical substance is active for a geometrid species.
