摘要 Saoura region is situated in the south west of dactylifera), where the authors note several oases such as: Algeria characterized by a height density of date palm trees (Phoenix Taghit, lgli, Beni Abbes... Despite this high density, the production of dates is still insufficient even for the local consumption, this is due to: Increasing salinity of water and soil in the old palm groves, the spread of many fungal diseases, where the most serious is the Bayoud (Fusaruim oxysporum), and finally insect pests, three of them remain the most serious: white scale locally named Semm (Parlatoria blanehardi), Boufaroua (Oligonyehus afrasiaticus), and Doud called dates worm (Ectomyelois ceratoniae). By using different trapping techniques, an entomofauna inventory was realized in the region of Saoura, where 3238 individuals are collected, distributed in 13 orders, 72 families and more than 132 species. The inventory will allow us to classify insects according to their economic importance, determine their life cycle and know their adaptation to date palm. The dynamics of these populations will be studied through the spatial-temporal repartitions. In parallel this study aims to identify the natural enemies (auxiliaries and parasitoids) of date palm pests in order to improve the biological control and this in hopes to ameliorate the production.
