白纹伊蚊、致倦库蚊、中华按蚊与五指库蚊扫描电镜观察

目的：了解白纹伊蚊、致倦库蚊、中华按蚊和五指库蚊生活史各期超微结构。方法：野外采集这4种蚊虫并行扫描电镜（SEM）观察。结果：4种蚊虫的幼虫栉齿、成蚊小盾板、蛹呼吸管和外壁纹饰和卵的超微结构上存在较大差异。结论：4种蚊虫生活史各期SEM观察均发现新的形态特征,这些特征有望应用于蚊虫分类学研究。

Scanning Electron Microscopy Observation on Aedes albopictus ,Culex quinquefasciatus ,Anopheles sinensis and Culex barraudi

Objective：To observe ultrastructures of the eggs,larvae,pupae and adults of Aedes albopictus,Culex quinquefasciatus,Anopheles sinensis and Culex barraudi.Method：The four species mosquitoes were collected in the breeding places,and the ultrastructures were observed under the scanning electron microscope（SEM）.Results：Some features could be clearly differentiate among these mosquitoes especially comb scales in larval stages,scutellum in adults,siphon and surface morphology in pupae,and some surface mophologic structures in eggs.Conclusion：New morphological features of these four species are found under SEM,which can be used for taxonomic identification.
