Abstract

Abstract Scanning electron microscopy on the ultrastructure of scales on the forewings and labial palpi suggests species-diagnostic differences among six sibling species of the genus Ostrinia Hübner. Among four species with small mid-tibiae, O. furnacalis (Guenée) and O. nubilalis (Hübner) show similar ultrastructure of the distal forewing scales, which is distinctly different from that of O. orientalis Mutuura and Munroe and O. dorsivittata (Moore). The diameter of windows between longitudinal ridges and cross ribs of forewing scales in O. dorsivittata is the largest among examined species, and clearly different from that in the other three small midtibiae species. Scales of the labial palpi of O. orientalis have indistinct vestigial windows; windows of O. nubilalis are more numerous and larger than in the other three small mid-tibiae species. Among two species with massive mid-tibiae, window diameter of forewing scales is larger in O. zealis (Guenée) than in O. scapulalis (Walker). Moreover, the number and diameter of windows in scales of the labial palpi differs between these two species. In addition to other known morphological differences, these ultrastructural differences provide further evidence that closely related Ostrinia species are distinct.

标题中国螟蝇属兄弟种超微结构的比较(鳞翅目:蛾科)

摘要:扫描电镜对鸵鸟属(Ostrinia h bner) 6个兄弟种的前翅鳞片和唇掌鳞片的超微结构进行了研究。在胫骨中部较小的4种中，O. furnacalis (guen)和O. nubilalis (h bner)的远前翅鳞片超微结构相似，与O. orientalis Mutuura、Munroe和O. dorsivittata (Moore)有明显差异。在所调查的物种中，背背飞蛾翅鳞纵脊与横肋之间的窗直径最大，与其他3种小型中胫科飞蛾的窗直径差异明显。东方瓢虫的唇掌鳞片有不明显的退化窗口;与其他三种胫骨中部的小物种相比，黄顶棘的窗数量更多，也更大。在胫骨中部较大的两种中，O. zealis (guen e)的前翅鳞窗直径大于O. scapulalis (Walker)。此外，这两个物种在唇唇的鳞片上的窗的数量和直径也不同。除了其他已知的形态学差异外，这些超微结构差异进一步证明了密切相关的玉米螟属物种是不同的。

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.
