Siirt province Sirvan district syrphidae family (diptera) fauna and its systematics

Syphids, which are generally large and attractively colored, mimic bees and wasps. Adult syrphids are often found on flowers and are important pollinators. Approximately 40% of their larvae are zoophagous, they generally feed on aphids, so they are important for agricultural ecosystems. This research is based on adult syrphids specimen collected from Şirvan district of Siirt province. Specimens collected from different locations using hand net were killed and preserved in ethyl acetate killing jars. The adult specimens obtained were strained in the entomology laboratory in accordance with standard museum methods and stored for identification in the Entomology Laboratory of the Plant Protection Department of Siirt University. Morphological characters were examined under a stereo microscope according to the literature and species identification of the specimen was made. As a result, a total of 14 genera and 23 species, including 10 species from the Syrphinae subfamily and 13 species from the Eristalinae subfamily, from Şirvan district of Siirt province (Cheilosia antiqua, Chrysogaster basalis, Episyrphus balteatus, Eristalinus sepulchralis, Eristalinus megacephalus, Eristalinus taeniops Wiedemann, Eristalis arbustorum , Eristalis tenax, Eumerus amoenus, Eupeodes corollae, Eupeodes luniger, Lejogaster tarsata, Melanostoma mellinum, Merodon velox, Neoascia podagrica, Neoascia tenur, Paragus bicolor, Paragus haemorrhous, Paragus pecchiolii, Paragus tibialis, Sphaerophoria rueppelli, Sphaerophoria scripta, Syritta pipiens) detection has been made. In the study, top and side photographs of each species and coordinate informations of the places maps of the localities where the species were collected are given. Additionally, the distributions of the detected species in the World and Türkiye are given.
