abstract
The present study aims at assessing entomofauna biodiversity in the Saline wetlands (Chott) located in the northeast of Algeria in the Setif region. To determine the environmental factors their predominant the distribution of insecta, an inventory was carried out to study the insect diversity and distribution in two stations were selected of Chott of Beida, during November 2014 to September 2015. The selected stations in the study area were divided to six transects according to distribution of plant and according to the soil salinity in each of stations. A total of 4213 insects belonging to 07 orders, 34 families, 57 species were collected from the Chott Beida. The Highest abundance of Coleoptera (49,12%) while lowest abundance of Collembola (05,26%). Highest number of (2520 individuals) found in station 2, while lowest number (1693 individuals) in station2. The Highest abundance of insects (50) were recorded in transect I station 2 and lowest abundance of species were recorded in transect III station 1. Diversity and Equitability indices showed highest values in station 1 (H =2,877; E= 0,7282), Similarly, while highest value at station 2 transect I (H =3,912; M= 12,53). Similarity Jaccard index (J) showed highest similarity was between station1 transect I and station 2 transect I (78,846%).
