    This study focused on the ecology of Orthoptera in a station at the Region of N'tissa (commune of Bounoura, Wilaya of Ghardaïa), belonging to the Saharan bioclimatic stage in mild winter. The surveys are carried out for 35 days, from 1 October to 5 November 2016. The Orthoptera inventory and the floristic surveys were carried out with a linear systematics, thus revealing the presence of fifteen species of Caelifera, divided into two families and Five sub-families, of which the Acrididae family is the most represented in terms of the number of species and number of individuals and the presence of 25 plant species in the same study region. The study of the diet of the nine selected species: Acrotylus patreulis (Hehrich-Schaeffer, 1838) and Pyrgomorpha cognata (Krauss, 1877), Acrida turrita (Linnaeus, 1758), Morphacris fasciata (Thunberg, 1815), Ochrilidia gracilis gracilis, Heteracris annulosa annulosa (Walker, 1870), Acrotylus longipes (Charpentier, 1845), Aiolopus strepens (Latreille, 1804) and Sphingonotus rubescens rubescens (Walker, 1870) shows that the most consumed plant species in the Study is Cynodon dactylon. Thus, the genus Acrotylus has a trophic range a little wider than the others.

    Etude des caractéristiques écologiques de quelques espèces d’Orthoptères Caelifères dans la région de Ghardaïa
    (Faculté des sciences de la nature et de la vie et des sciences de la terre, 2015) BENAOUMEUR, Azzedine; KERKAR, Hadj Brahim
    Abstract: The study of the ecology of the Acridiens was carried out in the area of Ghardaïa pertaining on the desert bioclimatic Floor. The inventory of recorded species revealed the presence of 15 locust species are divided into three families: Acrididae and Pyrgomorphidae and Acrydiidae. Whose family Acrididae is best represented. Both in number of species and number of individuals The study on the ecological characteristics of Orthoptérologiques stands in the region of Ghardaïa; allowed us to highlight the behavior of the main species studied. Through the ecological study we were able to distinguish between species that prefer moist environments such as Ochrilidia gracilis, species that tolerate temperature fluctuations and humidity such as Pyrgomorpha cognata, and species that prefer dry condition such as Sphingonotus rubescens. دراسة الجوانب البيئية للجراد أجريت في منطقة غرداية التي تنتمي الى المناخ ذات الطابع الصحراوي . المخزون من الأنواع المسجلة كشفت وجود 15 نوعا من الجراد , تنقسم الى ثلاثة عائلات : Acrididae و Pyrgomorphidae, وAcrydiidae . حيث ان عائلة Acrididae هي الافضل تقديما, من حيث عدد الانواع و عدد الافراد. دراسة الخصائص البيئية للOrthoptérologiques في منطقة غرداية. سمح لنا بتسليط الضوء على سلوك الأنواع الرئيسية التي شملتها الدراسة. من خلال الدراسة البيئية كنا قادرين على التمييز بين الأنواع التي تفضل البيئات الرطبة مثل هذا Ochrilidia gracilis، والأنواع التي تتحمل التقلبات في درجات الحرارة والرطوبة كما Pyrgomorpha cognata، والأنواع التي تفضل حالة جفاف .Sphingonotus rubescensمثل
