In the zone of Meskine (Maroua, Cameroon), observations have been made (dry season) on inventory species of Hoverflies depending on the diversity of food resources available. The main goal was to find Entomological knowledge which can facilitate the rise in yields in agricultural practices while preserving the environment in the agricultural site. The surveys were made every three days in the form of transect. Attractive plant species for the Syphidae are removed and the functional role of each species of Hoverfly determined. The results obtained helped to identify 21 species of Hoverflies. These species have been grouped in 8 genuss of which the genus Eristalinus was prominent with 12 species. Other genus were reduced to 40% namely Toxomerus, Melanostoma, Phytomia, Mesembrius, Asarkina, Paragus and Episyrphus. Three groups have been determined based on the frequency of occurrence of these Syrphidae: constant species, the incidental and accidental species. Floral visits of the flies listed were rated on 26 plant species including 8 peasant crops off season and 20 species around and between the line spacing of the cultures.
