    Description / Table of Contents: Résumé Dans un champ d'artichaut de la province de Salerno on a evalué la réponse des mâles de G. xanthenes à mélanges divers des constituants de la phéromone sexuelle produite par la femelle. Les meilleurs résultats ont été obtenus en employant un mélange de 5 mg Z11-16:Ald + 0.15 mg Z9-16:Ald + 0.15 mg 16:Ald + 0.12 mg Z11-16:OH, qui a capturé seulement les mâles de G. xanthenes en mesure 3–5 fois plus élevée que les pièges lumineux et ca. deux fois plus élevée que la femelle vierge. En partant du mélange base Z11-16:Ald (89–92%) + Z9-16:Ald (2–4%), l'addition de 16:Ald (2–4%) et de Z11-16:OH (2–3%) a causé un accroissement des captures de G. xanthenes et une diminution des captures de Heliothis armigera. Cela confirme l'action inhibitoire du Z11-16:OH à l'égard des males de H. armigera.
    Notes: Abstract Field responses of Gortyna xanthenes (Germar) males to traps baited with different mixtures of the female sex pheromone components were evaluated in an artichoke field. Catches were compared to those obtained by virgin females and light traps. The best results were achieved by utilizing a mixture of 5 mg Z11-16:Ald + 0.15 mg Z9-16:Ald + 0.15 mg 16:Ald + 0.12 mg Z11-16:OH, which captured only G. xanthenes males 3–5 times more than light traps and ca two times more than one virgin female. Starting from the basic mixture Z11-16:Ald (89–92%) + Z9-16:Ald (2–4%), the addition of 16:Ald (2–4%) and of Z11-16:OH (2–3%) produced an increase of G. xanthenes and a decrease of H, armigera (Hb.) catches. The inhibitory action of Z11-16:OH towards H. armigera males was confirmed.
