摘　　要：【目的】调查重庆市城口县双翅目(Diptera)食蚜蝇科(Syrphidae)昆虫的种类并进行区系分析。【方法】在城口县所辖全部25个乡(镇、街道)内用样线法、灯诱法、马来氏网法等系统地开展了食蚜蝇科昆虫调查;对所有标本开展了形态学鉴定和物种描述;编制了分种检索表,并进行了区系分析。【结果】采集和检视了城口县食蚜蝇科的昆虫标本共400余头;经鉴定,它们分属2亚科、6族、10属、13种,其中3族、6属、9种为城口县新纪录族、属、种。城口县的食蚜蝇科昆虫具有东洋界和古北界的成分,但以东洋界的成分占主体;而它们在中国动物地理区系中具有9种不同的物种区系分布型,所有记述的种类都分布于东洋界的华中区和古北界的华北区。【结论】研究结果有助于城口县食蚜蝇科昆虫的正确鉴定、保护和利用。[Purposes]To understand the species biodiversity,and faunal distribution and characteristics of the family Syrphidae(Diptera)from Chengkou County of Chongqing.[Methods]The insects of Syrphidae were collected by using artificial,light trap and Malaise trap methods over 25 towns of Chengkou County.The morphological identification and description,the key to species and the fauna analysis were carried out for all collected species.[Findings]Over 400 specimens of Syrphidae were collected and investigated,and a total 13 species were identified and described,which belong to 10 genera,6 tribes and 2 subfamilies.Out of these taxa,three tribes,six genera and nine species are new records to Chengkou County.These 13 species belong to both Oriental and Palearctic regions in geographical distribution,but the composition of the Oriental region is dominant.There are nine different species distribution types in biogeography.All of these species occurred in the Central China subregion of the Oriental region and the North China subregion of the Palearctic region.[Conclusions]The result will contribute to the correct identification,protection and utilization of the family Syrphidae in Chengkou County.
