Abstract

The major sex pheromone component from female moths of Retinia metallica (Busck) was identified as Z7,E9-dodecadienyl acetate (Z7,E9-12:Ac) by a combination of electroantennographic (EAG), gas chromatographic (GC), and mass spectrometric analyses. In field tests, males of R. metallica were strongly attracted to Z7,E9-12:Ac. Addition of Z7,Z9-12:Ac, E7,Z9-12:Ac, Z7,E9-dodecadienol (Z7,E9-12:OH), andZ7-dodecenyl acetate (Z7-12:Ac) to Z7,E9-12:Ac did not significantly alter trap catch. However, the addition of E9-dodecenyl acetate (E9-12:Ac) and Z9-12:Ac reduced trap catch. Trap catch was affected by height of placement; traps placed in the upper third of the tree (6 m) caught significantly more males than traps placed at lower heights.

Résumé

La composante majeure de la phéromone sexuelle des femelles de Retinia metallica (Busck) a été identifiée comme étant le Z7,E9-dodécadiènyl acétate (Z7,E9-12 : Ac) par la combinaison d’analyses électroantennographique, chromatographique en phase gazeuse et spectrométrique de masse. Lors de tests en champ, les mâles de R. metallica étaient très attirés par le Z7,E9-12 : Ac. L’ajout de Z7,Z9-12 : Ac,E7,Z9-12 : Ac,Z7,E9-dodécadiènol (Z7,E9-12 : OH), et Z7-dodécényl acétate (Z7-12 : Ac) au Z7,E9-12 : Ac n’a pas affecté significativement les captures. Cependant, l’ajout de E9-dodécényl acétate (E9-12 : Ac) et de Z9-12 : Ac a réduit les captures. Les captures étaient affectées par la hauteur de piégeage : les pièges situés dans le haut des arbres (6 m) ont capturé plus de mâles que ceux placés plus bas.
