The inventory of invertebrates on persimmon cultivation using two methods of sampling, Barber traps and colored traps in Mechtras region (Tizi-Ouzou) Algeria, allowed us to collect 115 species divided into 58 families, belonging to 13 orders and 6 classes. The values of the centesimal frequencies applied to invertebrates orders identified in the studied plot vary from one type of trapping to another, each sampling method relates to a representative order group. The diets of insects are extremely diverse, due to the structures and function of the mouthparts, the structural and functional division of the digestive tract; we have established 8 trophic classes. Shannon-Weaver diversity index values are quite high in the study plot. The fairness obtained for each type tend towards 1, which reflects a balance between the species.
