    ABSTRACT
    The contribution to the study of the biodiversity of Diptera associated with the cultivated olive tree took place over a year from December 2018 to November 2019, in two stations located in the west of Algeria. The aim of this present work is to learn about the biodiversity of Diptera associated with the olive tree cultivated in the Tiaret region. Sampling frequency was on the order of one outing per month using the yellow plates and barber jars to collect the specimens. We identified 1124 individuals or 46 species belonging to 29 families. The Sciaridae family is the most representative in Ain Guesma station with a relative abundance AR% of 23%. While in the station of Oued lili the Chirinominidae family is the most captured, at 18.52%. The two stations present a great diversity of species (H ’= 3.58 Ain Guesma, H’ = 3.65 in Oued Lili). The equity of the species identified in this study is greater than or equal to 0.76.

    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.
