| Résumé : | Methyl salicylate and (-)-(1 R,5 S)-myrtenal stimulate specific olfactory cells in the primary rhinaria on the sixth and fifth antennal segments, respectively, of the black bean aphid, Aphis fabae. In behavioral studies employing a linear track olfactometer, both compounds were repellent to A. fabae and also inhibited attraction to volatiles from its host, broad bean (Vicia faba). Methyl salicylate is associated with secondary metabolite-based defense in plants, and the monoterpenoid (-)-(1 R,5 S)-myrtenal is metabolically related to (-)-(1 S,5 S)-alpha-pinene, an abundant component of defensive resins produced by gymnosperms. It is argued that these two compounds are employed by A. fabae as indicators of nutritionally unsuitable or nonhost plants. |
