Inventaire entommofaunistique dans la station de Sebkhet Safioune

Abstract

The present work is about the inventory of the arthropods in the station of Sebkhet Safioune (32.27°N, 5.36°E) by three methods of piègeage (pots to Bore, net troubleau and net submersion). With the first technique 52 species of arthropods are counted of survey middle. They are 3 classes (Arachnida, podurata and Insecta). The class of the Insectas dominates 73,6% distinctly (> 2 x m; m = 33,3%). according to the orders, The Hymenopteras that also dominate 37,8% (> 2 m; m = 4 %). Of this order, family of the Formicidaes who contributes with a big number of individuals with a rate 30,1% (> 2 m; m = 3,4%). The technique of net troubleau has us permits to get 3 species distribute in 2 order and 3 families. The species Cyclorrhapha sp.ind intervenes with 57,1% (<2 m; m = 33,3%). The one of the net submersion technique one harvested 3 species, of the class insecta, the species the more dominates is Diptera sp.ind (61,7%> 2 m; m = 33,3%).
