We aspire through this international Webinar, to draw a more complete picture of the evolution of scientific investigations on the Algerian fauna and the current state of research and conservation of this fauna in Algeria.  The meeting of researchers online will certainly be able to enrich the debate on the problem of the depredation of certain bio-aggressors in order to update the biological means used to better manage agro-ecosystems.

         Thus, this meeting will make it possible, on the one hand, to establish a forum for the exchange of knowledge and experiences in natural and cultivated environments and to assess the impact of anthropization and climate change on the biodiversity of these environments, and on the other hand, to propose solutions for sustainable development .
