Invertebrate’s diversity on persimmon crop (Diospyros kaki Thunb.) at low altitude in Mechtras region, North Algeria

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.
