摘要

摘要/ Abstract摘要:本研究以麦蠓(Sitodiplosis mosellana)(双翅目:姬蚊科)为研究对象，将其与小麦穗(Triticum aestivum L.，禾本科)接触，使其在不同基因型或生长阶段的麦穗上进行产卵。花期后的“Roblin”和花期前的“Key 10”的尖刺被认为会阻止产卵。这些穗状物释放的挥发物抑制了花期前“Roblin”的产卵，这是产卵的首选。花期前‘Roblin’穗释放的挥发物对花期前‘Key 10’的产卵没有促进作用。抗性基因型和威慑性生长阶段的小麦产卵减少与威慑性挥发物的产生一致，而不是缺乏刺激挥发物。

Volatile Compounds from Non-Preferred Wheat Spikes Reduce Oviposition by Sitodiplosis mosellana

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.

期刊介绍： French translation follows/le français suit Published since 1868, this peer-reviewed bimonthly publication is the official journal of the Entomological Society of Canada. Available via the internet and with hardcopy distribution to 55 countries, its research papers and notes are relevant to entomologists and other biologists around the world. In addition to being a venue for topical reviews and forum discussion, The Canadian Entomologist publishes current research in all facets of entomology, including systematics and morphology, molecular and developmental biology, ecology and behaviour, biodiversity and evolution, insect management, entomological techniques, and other relevant subject areas. Contributions are published in English or French. Authors will not pay page charges, and will experience fast, high quality reviews of their papers.Publiée depuis 1868, cette publication bimestrielle avec comité de lecture est la revue officielle de la Société d’entomologie du Canada.
