Diversity, Composition and Systematic Structure of the Terrestrial Entomofauna of a Ramsar site: The Biological Reserve of Sidi Boughaba, Mehdia (Morocco)

Abstract

The region of Sidi Boughaba which is an important biological reserve (Northwest of Mehdia, Morocco) offers a favorable conditions for the development of diversity of the wildlife. It is characterized by a sub-humid bioclimate and a mild winter. The objective of the present study is to make an entomological inventory in five different areas of floristic cortege perspective (herbaceous, shrub) and other medium (soil, water). A statistical study was performed by environmental indices of composition and structure. Sampling was done from mid-April 2013 to December 2013. The analysis of the entomofauna revealed the existence of 73 species distributed in 7 Systematic orders and 28 families. Beetles are represented by 19 species, Orthoptera by 13, Diptera by 12 species; Hemiptera, Hymenoptera and Lepidoptera are represented by 8 species for each; Odonata come in last place with 5 species. Similarly, the results showed that the values of Shannon-Weaver diversity vary between 2.654 and 3.411 which express the diversity of the sampled population.
