    ABSTRACT
    The present study concerns arthropod populations in two different environments, cultivated and natural regions of Djanet. We conducted qualitative and quantitative surveys over two seasons (summer and winter). Three sampling methods were used: pitfall traps, sweep nets, and yellow pan traps. Overall, 4480 individual arthropods were captured representing 191 species, 4 classes, 21 orders and 106 families, distributed across four study sites, namely: Lokmane and El Mihane stations for the cultivated environment and Teghargharte and Iffoutten stations for the natural environment. A total of 112 species of arthropod species were captured by pitfall traps, with Hymenoptera accounting for 69% of the species. Sweep netting generated 65 species of arthropods, with Orthoptera accounting for 36% of the captures. Yellow pan traps led to the capture of 82 species of arthropods, with dipterans most attracted by this type of trap with a rate of 38%. The 17 species of Orthoptera that we captured in the region of Djanet belonged to 7 families and 2 orders, in which the species Tridactylus variegatus was the most abundant.

    ABSTRACT
    This work focuses on the study of the diet of the ant Cataglyphis bicolor (Fabricius, 1793) (Hymenoptera Formicidae) in the natural reserve of the Reghaïa wetland through the analysis of two nests. This study shows that Hymenoptera dominates in the trophic menu of this species at 92.7 % for Nest 1 and 87% for Nest 2, with a total of 60 species divided between 3 classes, 10 orders and 31 families. The most consumed species by C. bicolor is Messor barbarus (Linnaeus, 1767) (Hymenoptera Formicidae) with 87% (Nest 1) and 82.2% (Nest 2). In terms of biomass, a species of Coleoptera dominates either Ophonus sp. (B.% = 9.36 %). Messor barbarus dominates in relative abundance and has only a very small part of the biomass ingested (0.37%). The size of C. bicolor prey species is between 1 and 24 mm for Nest 1 and 1 and 30 mm for Nest 2.
