(Z,E)-9,12-Tetradecadien-1-ol: a Major Sex Pheromone Component of Euzophera pyriella (Lepidoptera: Pyralididae) in Xinjiang, China

SUMMARY

The moth Euzophera pyriella (Lepidoptera: Pyralididae) is one of the important fruit pests in the pear orchards of Xinjiang, China. Extracts from the sex pheromone gland of virgin female moths were analyzed with gas chromatography-mass spectrometry (GC-MS). Two components, (Z)-8-Dodecenyl acetate (Z8-12:Ac) and (Z,E)-9,12-Tetradecadien-1-ol (Z9E12-14:OH), were identified in extracts. Z9E12-14:OH was the most active in electroantennogram (EAG) and field attraction studies. Z8-12:Ac and other common components identified in Euzophera (including Z9-14:Ac, Z9-14:OH and Z9E12-14:Ac) neither elicited significant EAG responses nor attracted many males in field tests. Binary mixtures of Z9E12-14:OH and Z8-12:Ac in different ratios were active in field tests, but the number of male moths trapped did not differ between these binary mixtures and Z9E12-14:OH alone. We conclude that Z9E12-14:OH is a major component of the female sex pheromone of E. pyriella and could be used as an attractant for monitoring the populations of this moth species. La polilla Euzophera pyriella (Lepidoptera: Pyralididae) es una de las plagas frutales importantes en los huertos de pera en Xinjiang, China. Se analizo los extractos de la glandula de feromona sexual de las polillas hembras virgenes mediante la espectrometria de masascromatografia de gases (EM- CG). Dos componentes, (Z)- 8 -dodecenilo de acetato (Z8-12:Ac) y (Z,E)-9,12-Tetradecadien-1-ol (Z9E12-14:OH), fueron identificados en los extractos. Z9E12-14:OH fue el mas activo en electroantenograma (EAG) y en los estudios de atraccion del campo. Z8-12:Ac y otros componentes comunes identificados en Euzophera (incluyendo Z9-14:Ac, Z9-14:OH y Z9E12-14:Ac) no provocaron respuestas de EAG significativas tampoco atrajeron a muchos machos en las pruebas de campo. Las mezclas binarias de of Z9E12-14:OH y Z8-12:Ac en diferentes proporciones fueron activos en las pruebas de campo, pero el numero de polillas macho atrapados no fue diferente entre estas mezclas binarias o de solo Z9E12-14:OH. Llegamos a la conclusion de que Z9E12-14:OH es un componente principal de la feromona sexual femenina de E. pyriella y podria ser utilizado como un atrayente para el monitoreo de las poblaciones de esta especie de polilla. View this article in BioOne
