Impact of Habitat on the Development of Coprophagous and Xylophagous Coleopteran Insects in the Park of Bamimgui-Bangoran (Central African Republic)

Coprophagous and Xylophagous Coleopterans are equally impacted by the fragmentation of ecosystems and are recognized for their character as indicators of certain ecosystem functions, such as the recycling of organic matter and pollination. Thus, as part of the program to restore degraded ecosystems in protected areas and others sectors of the Bamingui-Bangoran Prefecture in the Central African Republic (CAR), an inventory of insect species according to their ecological profile is needed. Insects were collected over 8 hectares corresponding to 6 different habitats in the Bamingui-Bangoran park. Sixty different traps were installed in each habitat with 100 meters of distance between the traps. The measured parameters are the number of individuals collected per week. As results, 8 coleopteran families (4 Coprophagous families and 4 Xylophagous families) were identified. The Coprophagous and Xylophagous Coleopterans were much abounded in grassy savannahs with much mixing trees with Imperata cylindrica and in grassy and shrubby savannas with many flowering plants (Melliferous) and less abounded in grassy and shrubby savannahs domined by Imperata cylindrica. However, repartitions of individuals fit uniform distribution in all coleopteran families belonging to Xylophagous group whereas in Coprophagous, uniform distribution fit was established only for one family.
