摘要

速蝇科是双翅目昆虫中最多样化的分支之一。所有的速虫都是昆虫和其他节肢动物的寄生蜂,因此被认为是生物害虫防治的重要来源。触角是蜘蛛科昆虫最重要的嗅觉器官,在它们的生活中起着关键作用,尤其是在寻找寄主方面,触角的超微结构细节可以为系统发育研究和了解它们的适应进化提供有用的特征。尽管触角在生态学和进化上具有重要意义,但目前对触角超微结构的了解很少。本研究对四亚科(Phasiinae, Dexiinae, Tachininae, Exoristinae) 11个族13属13种触角感器进行了研究:Beskia aelops Walker, Trichodura sp., Voria uralis (falln), Zelia sp., clindromyia carinata Townsend, Phasia xenos Townsend, Neomintho sp., Genea australis (Townsend), Copecrypta sp., Hystricia sp., Belvosia sp., Leschenaultia sp.和Winthemia pinguis (Fabricius)。用扫描电镜观察了触角感受器的类型、长度和分布。我们总结了29个变异性状,并在亚家族、部落和属/特异水平上评价了它们的系统发育信号,表明触角超微结构可以作为系统发育分析的可靠性状来源。我们的研究结果表明,触角的超微结构具有显著的多样性。

Comparative morphology of antennal ultrastructure in Tachinidae parasitoid flies (Diptera): The phylogenetic importance of antennal sensilla

Tachinidae are one of the most diverse clades of Diptera. All tachinids are parasitoids of insects and other arthropods, and thus are considered an important source of biological pest control. Antennae are the most important olfactory organs of Tachinidae playing key roles in their lives, especially in locating hosts, and details of antennal ultrastructure could provide useful features for phylogenetic studies and understanding their adaptive evolution. Despite the ecological and evolutionary importance of antennae, the current knowledge of antennal ultrastructure is scarce for Tachinidae. Our study examined antennal sensilla of thirteen species belonging to thirteen genera within eleven tribes of all the four subfamilies (Phasiinae, Dexiinae, Tachininae, and Exoristinae): Beskia aelops Walker, Trichodura sp., Voria ruralis (Fallén), Zelia sp., Cylindromyia carinata Townsend, Phasia xenos Townsend, Neomintho sp., Genea australis (Townsend), Copecrypta sp., Hystricia sp., Belvosia sp., Leschenaultia sp., and Winthemia pinguis (Fabricius). Types, length and distribution of antennal sensilla were investigated via scanning electron microscopy (SEM). Our comparative analysis summarized 29 variable characters and we evaluated their phylogenetic signal for subfamilial, tribal and generic/specific levels, showing that antennal ultrastructure could be a reliable source of characters for phylogenetic analysis. Our findings demonstrate the remarkable diversity of the antennal ultrastructure of Tachinidae.

期刊介绍: Arthropod Structure & Development is a Journal of Arthropod Structural Biology, Development, and Functional Morphology; it considers manuscripts that deal with micro- and neuroanatomy, development, biomechanics, organogenesis in particular under comparative and evolutionary aspects but not merely taxonomic papers. The aim of the journal is to publish papers in the areas of functional and comparative anatomy and development, with an emphasis on the role of cellular organization in organ function. The journal will also publish papers on organogenisis, embryonic and postembryonic development, and organ or tissue regeneration and repair. Manuscripts dealing with comparative and evolutionary aspects of microanatomy and development are encouraged.
