An approach ofthe composition and structure of populations of different insect taxa found incereal fields (durum wheat barley), in the Tissemsilt region. A fairly comprehensive list of the insect population by pot-barbers has highlighted a repertoire of 26 species. The order Coleoptera is the most encountered with 13 species, including 6 different families, five species are noted for the order Diptera divided into four families Muscidae, Syrphidae, Phoridae and Sacrophagidae. And to a lesser degree come Hymenoptera (6 species), Heteroptera (1 species) and Lepidoptera (1 species). In addition, the results reveal the existence of four harmful species (Curculionidae (02), Syrphidea, (1), Pentatlmidae with only one species) and nine useful insects (Carabidea (04), Ciccalidae (1), Apidae (2 ) and Formacidae (2). This distribution is closely related to environmental factors such as precipitation, temperature and probably also to landscape elements, such as the cultivation in place, which directly influences the composition of the entomofauna.
