Catalogue commenté des coléoptères des dunes mobiles de la frange septentrionale et de la région orientale du Maroc

Abstract

This work focuses on the study of spatial distribution of beetles population in the mobile dunes of the northern fringe of the eastern region of Morocco. This study is spread over a route of 4000 km from the Guercif dunes toward the large dunes of Merzouga (Sahara) passing by dunes of northeast of Missour, Midelt, Ain Beni Methar, Tendrara, Rich, Boulmane, Bouârfa, Boudnib and Erfoud. Entomological population is dominated by the family Tenebrionidae which is well suited to this type of extreme weather environment. The super family Scarabaeoidea came in the second place and whose species are mostly attracted by the dung feces. Large taxonomic richness is noted in Tendrara, Figuig and Bouârfa. Recorded values of abundance were high in the Saharan and desertic stations of Figuig, Erfoud, Merzouga and Tendrara.
