摘　　要：[Objective] The aim was to explore the species diversity of flower-visiting Syrphidae in the farmland of Hanzhong area.[Method] Based on the sample collection and the sorting and identification of collected specimens and literature,the species and their seasonal changes of flower-visiting Syrphidae in the agroecosystem of Hanzhong area were systematically analyzed.[Result] 5 015 specimens of Syrphidae were cheaked in this study,and 141 species of 53 genera of 16 families in three subfamilies of flower-visiting species of Syrphidae were identified in farmland of Hanzhong area,in which 65 species were Syrphinae;72 species were Milesiinae;while four species were Microdontinae.The species of Syrphidae in this region were active in April,May,June and July.There were two dominant species in this region,including Episyrphus balteatus and Eristalis tenax.[Conclusion] This study had provided theoretical basis for the studies on the flower-visiting habit and fecundation of insects of Syrphidae in this area.[目的]调查汉中地区农田生态系统访花食蚜蝇的物种多样性。[方法]通过标本采集和馆藏标本整理、鉴定,结合文献资料,对汉中地区农田生态系统中访花食蚜蝇的种类及其季节性变化进行了系统统计。[结果]共鉴定食蚜蝇科昆虫标本5015头,汉中农田生态系统中分布有访花食蚜蝇3亚科16族141种,其中食蚜蝇亚科65种;迷蚜蝇亚科72种;巢穴蚜蝇亚科4种。食蚜蝇科昆虫成虫主要活动在每年的4～7月,优势种为黑带食蚜蝇和长尾管蚜蝇。[结论]为今后研究汉中地区食蚜蝇科昆虫的访花习性和传粉作用提供了理论依据。
