Inventaire des Acridiens dans la région de Ghardaïa

Abstract

An inventory of locusts has been achieved in the region of Ghardaïa the study was conducted in three stations. S1 and cultured medium (El- Atteuf), S2 medium uncultivated (El- Atteuf) and palm (GHARDAIA). The achievement of this inventory was made from sampling method (sampling square, the sweep net). Orthoptera of samples are sampled from 28 species These species are distributed into two sub- orders, three super- families, families fives and eleven subfamilies. Ecological conditions are essentially; climate, soil, and vegetation type. Seem to play a major role in the distribution of Orthoptera. In fact, some species of grasshoppers are called drought tolerant and thermophilic , are associated with open habitats , dry and hot , this is the case, for example Sphingonotus rubescens ; else say hygrophile and rain , which like cutlery and wetland habitats as is the case Omocestus lucasi , others say eurythermal and euryhygres capable of humidity, this is the case Acrotylus patruelis. The main purpose of our study is to determine which species adapt to the climate of the study area and ecological changes as a result, the study of their ecological characteristics and life cycles to define the appropriate control methods against this type of insect and the damage that cause it.
