Initiation à la description morphologique et la systématique du genre Sphingonotus (Oedipodinae-acrididae –caelifera) Dans la région de Ghardaïa

Abstract

This study was performed in two different environments (El-Atteuf and BeniIzguen) in the region of Ghardaia. The inventory of grasshoppers and the sampling has identified 21 species, belonging to three families and six subfamilies. The study relative to the biological characteristics of the main species of Sphingonotus in the Ghardaia region allowed us to highlight the dynamics of key species studied. Through the ecological study, we could therefore shows that the kind Sphingono-tus frequent dry environments with low vegetation cover. The morphometric study shows a size of distinction generally, both in males than in females: females are much larger than males.
