Abstract

Inclusion of traces of (Z)-11-hexadecenol in synthetic sex lure traps for bertha armyworm moths resulted in diminished trapping; substantial amounts of (Z)-9-hexadecenol or (Z)-11-hexadecenal were also suppressant. Of 22 other oxyolefins tested, (Z)-7-dodecenyl acetate acted in conjunction with the bertha lure components to attract Euagrotis tepperi (Walker) to traps, and (Z)-7-tetradecenyl acetate similarly to attract Lacinipolia vicina (Grote). No tested additive improved either the potency or the specificity of the original bertha blend.

Résumé

L'inclusion de traces de (Z)-11-hexadécénol dans l'appât sexuel synthétique contenu dans les pièges à papillons de la légionnaire bertha a réduit le piégeage; des quantités substantielles de (Z)-9-hexadécénol ou de (Z)-11-hexadécénal ont aussi eu effet réprimant.

Des 22 autres oxyoléfines étudiées, l'acétate de (Z)-7-dodécényl a agi conjointement avec les composantes de l'appât pour la légionnaire bertha en attirant Euagrotis tepperi (Walker) aux pièges, et, de façon similaire, l'acétate de (Z)-7-tetradécényl, attirant Lacinipolia vicina (Grote). Aucun des additifs étudiés n'a amélioré la force ou la spécificité du mélange original pour la légionnaire bertha.
