Abstract

Female wheat midges, Sitodiplosis mosellana (Géhin) (Diptera: Cecidomyiidae), were provided with wheat spikes, Triticum aestivum L. (Poaceae), for oviposition while being exposed to air that had passed over wheat spikes of contrasting genotype or growth stage. Spikes of postanthesis ‘Roblin’ and preanthesis ‘Key 10’ are known to deter oviposition. Volatiles emitted by these spikes suppressed oviposition on preanthesis ‘Roblin', which is preferred for oviposition. Volatiles emitted by spikes of preanthesis ‘Roblin’ did not increase oviposition on preanthesis ‘Key 10'. Reduced oviposition on a resistant genotype and on a deterrent growth stage of wheat is consistent with production of deterrent volatiles rather than a lack of stimulatory volatiles.

Résumé

Nous avons fourni des épis de blé, Triticum aestivum L. (Poaceae), à des femelles de la cécidomyie du blé, Sitodiplosis mosellana (Géhin) (Diptera : Cecidomyiidae), pour la ponte, alors qu'elles étaient exposées à de l'air qui avait traversé des épis de blé de divers génotypes ou stades de croissance. On sait que les épis ‘Roblin’ après l'anthèse et que les épis ‘Key 10’ avant l'anthèse inhibent la ponte. Les substances volatiles émises par ces épis empêchent la ponte sur ‘Roblin’ avant l'anthèse qui est le substrat préféré pour la ponte. Les substances volatiles émises par les épis ‘Roblin’ avant l'anthèse n'augmentent pas la ponte sur ‘Key 10’ avant l'anthèse. La réduction de la ponte sur un génotype résistant et sur un stade de croissance dissuasif chez le blé est compatible avec la production de substances volatiles dissuasives plutôt qu'avec l'absence de substances volatiles stimulatrices.
