Abstract

This work is carried out at the level of two regions, namely the region of (GeurarraGhardaïa) and the region of El-Menia, in order to have an idea of the importance of the pests of wheat crops under pivot within the arthropodofauna, an inventory is carried out over a period of three months (January, February and March 2023), thanks to the use of three trapping methods, in particular food traps, Barber pots and yellow traps. The sampling made it possible to identify arthropod individuals, divided into 3 classes, 9 orders, 21 families, 34 species. Insecta 161 are the most identified in the two study regions, the first region (AR = 81.48%), the second region (AR = 100%). According to the orders, it is the Diptera who dominate for the two regions. While the most dominant families in both regions are Muscidae with a rate equal to Regarding the total number of species captured by different trapping methods during .%25 the sampling period is 34 species. Examination of captured pests reveals the existence of 34 individuals divided among 10species, including the species of ,Aphis fabae is the most noted .in the two study regions
