Abstract

Male moths of striped cutworm, Euxoa tessellata (Harris), were specifically attracted to blends of Z-5-tetradecenyl acetate or Z-5-hexadecenyl acetate with Z-7-hexadecenyl acetate. The most satisfactory quantities of these components per septum dispenser were: Z-5-tetradecenyl and Z-7-hexadecenyl acetates at 2.5 and 500 μg, or Z-5-hexadecenyl and Z-7-hexadecenyl acetates each at 500 μg. The addition of 1.0% Z-7-hexadecenol relative to Z-7-hexadecenyl acetate in either of these blends inhibited the attraction of males. The blend involving Z-5-tetradecenyl acetate is recommended for monitoring purposes.

Résumé

Les papillons mâles du ver-gris rayé Euxoa tessellata (Harris), ont été attirés spécifiquement par des mélanges de Z-5-tétradécényl acétate ou de Z-5-hexadécényl acétate avec du Z-7-hexadécényl acétate. Les quantités les plus appropriées de ces composantes par septum dispensateur étaient : 2.5 et 500 μg pour les acétates de Z-5-tétradécényl et de Z-7-hexadécényl, ou de 500 μg chacun pour les acétates de Z-5-hexadécényl et de Z-7-hexadécényl. L'addition de 1% de Z-7-hexadécénol par rapport au Z-7-hexadécényl acétate dans l'un ou l'autre de ces mélanges prévient l'attraction des mâles. Le mélange contenant du Z-5-tétradécényl acétate est recommandé pour la surveillance des populations.
