Abstract

The inventory of grasshopper and locust fauna in several stations in Eastern Algerian revealed the presence of more than 80 species. They are belonging to five families. Most of the collected species are belonging to family Acrididae. Consideration of the work carried out in other Algerian stations has made it possible to define certain climatic constraints of most species. The arid and semi-arid climate is the most favorable conditions for the presence of grasshopper fauna. The desert locust, Schistocerca gregaria Forskal, 1775), the migratory locust, Locusta migratoria (Linne, 1758), the Egyptian locust, Anacridium aegyptium (Linnaeus, 1764), The Boukrouma locust Ocneridia volxemii (I. Bolivar, 1878), the Barbary locust, Calliptamu sbarbaru sbarbarus (Costa, 1836) and the Moroccan locust Dociostaurus maroccanus (Thunberg, 1815) could be economic insect pests in arid and semi-arid regions.
