库蠓属是蠓科中最大的一个属，该属昆虫可骚扰吸血并传播多种人、畜病原生物，是重要的媒介昆虫。当前对该属缺乏完善的分类系统，特别是亚属、种团阶元界限上非常混乱，亟需进行系统地厘定和体系的进一步探讨研究。由于该族昆虫个体微小、采集、制作困难、近似种类繁多、种群认识不足等问题存在，导致鉴定错误和学名混淆等问题经常出现，从而使调查研究等工作受到很大的局限。本项目将运用形态分类学和分子生物学相结合的方法，对该属进行系统整理和修订，探讨其系统发育关系和分类体系；采用几何形态学方法对库蠓翅的图像进行描述与分析，并建立一套检测体系；利用扫描电镜获得库蠓重要特征的超微形态，进行比较形态分析。本项目实施，对中国和世界蠓科昆虫的分类、鉴定、防控以及生物多样性等研究工作具有重要意义。本项目预期获得如下成果：培养硕士研究生3人；出版专著1部；在核心期刊以上发表论文6-8篇，其中SCI收录论文3-4篇。

The genus Culicoides Latreille is the largest genera of Ceratopogonidae. The biting midges cause a significant biting nuisance to humans, livestock and equines, and are the biological vectors of a range of internationally important pathogens of both veterinary and medical importance. Until now there is no complete taxonomic study to the genus, especially the boundary of subgenus and group, so it is urgent to systematically define and further study the taxonomic system. Furthermore, misidentifications and incorrect records plus confused scientific names are general owing to the tiny size, difficulties in collecting and slide-mounting specimens, presence of many similar species in morphology, and insufficient recognition to species population. Thus, this project aims to conduct a systematic review to the genus Culicoides, discuss the phylogenetic relationships and reasonable taxonomic system according with natural evolution using morphologic and molecular methods based on materials and experiences of years. The characteristics of the wing are described and analyzed by geometric morphometrics method, establish a set of detection system. The ultra-morphology of some features are obtained by Scanning Electronic Microscope, complete the comparative morphologic analysis. The implement of this project will be of great significance to not only classification and control of Ceratopogonidae domestically and internationally, but also research of global biological diversity. The project is expected to achieve the following results: culture 3 graduate students, publish monograph “Culicoides of China”; publish papers 6-8, including SCI papers 3-4.
