Assessment of the biodiversity of agricultural arthropods of the nord-est Souk Ahras (Algeria)

Abstract

Agricultural territories represent the main habitats of ordinary biological diversity in the municipality of Tiffech and Oum Ladayem metropolitan. Several actions, to increase the biological diversity, are lead on these territories at different scales (Tiffech and Oum Ladayem, National, land scale or farm scale). The aim of these actions is to stop the loss of biodiversity. But scientific methods are necessary to evaluate the results of these actions. The method used for 3 years, in the study of the arthropoda biodiversity at the “Tiffech and Oum Ladayem” is one of these methods. In fact, the Rapid Biodiversity Assessment (RBA) is a simple method which permits an evaluation of the arthropods’ biodiversity, with a morphologic determination method, parataxonomy. The results obtained show the importance of the presence of Ecological Reservoir Zones or semi-natural habitats within monoculture territories (here leguminous peas), in order to preserve biodiversity in arthropods.
