ABSTRACT. An inventory of invertebrates on cherry cultivation using two methods of sampling, pitfall traps and coloured traps, in the Thakhelijt region (Ain El Hammam, Tizi-Ouzou) of Algeria, allowed us to collect 107 species divided into 61 families, belonging to 21 orders and 7 classes. The values of the centesimal frequencies applied to invertebrate orders identified in the studied plot vary from one type of trapping to another, with each sampling method relating to a representative order group. The diets of invertebrates are extremely diverse, due to the structures and function of the mouthparts, and the structural and functional division of the digestive tract. Distribution is defined according to the different trophic categories according to our personal observations and the bibliography consulted. It was possible to distinguish 10 large groups among the 107 insect species selected. Shannon-Weaver diversity index values are quite high in the study plots, with H’ = 5.78 bits for pitfall traps and H’ = 4 bits for coloured traps. The fairness obtained for each type of trap varies from E = 0.88 to E = 0.90; these values tend towards 1, which reflects a balance between the host and parasite species in the environment.
