Abstract:
The objective of this study is to inventory the arthropods in two stations (agricultural; fallow)
located in Oued Ntissa (Ghardaïa) Its geographical coordinates are (latitude 32°26'46.9''N,
longitude 3°38'51.4'' E) by four sampling methods in station1 (Barber pots, sweep net, sticky
plates and hand capture). This work allowed the census of 284 species distributed on 21
orders and 138 families, and 3 classes. Species ranks second and counts covering a rate of
16%, the order of Coleoptera 32 species covering a rate of 12%. While the isopod order is
poorly represented with only one species, i.e. a rate of 1%. And station (2), The order of
Diptera, 23 species is the most diversified i.e. a rate of 30%, The order of Coleoptera covering
16 species a rate of 21%, and the Order Hymenoptera 18 species i.e. a rate of 15%. And the
Collembola order is poorly represented with a single species at a rate of 1%.
D'Oued Ntissa seems to be the richest species of Orthoptera. Relative species abundance data
showed that (Hymenoptera, Depitera, Coleoptera) dominated most of the two sites. Value of
Shannon's Diversity Index and Abundance stocks gradually decline in spring and summer
when they are at their peak, then decline in winter. Orthoptères is looking for a high-density
agricultural area on the fallow station .
