Beetles abundance and diversity in relation with plant diversity in banco national park and human disturbed areas around

The aim of this work is to study the correlation between plant diversity and beetles populations in Banco National Park and Human modified areas around. Thus, Beetles and flora inventory has been made in the forest and Human modified areas. The floristic inventory required two sampling methods: roving survey method and surface survey method. For beetles capturing, yellow ground trap, yellow height trap, pitfall trap and screen trap were used. A total number of 155 plant species divided into 136 genera belonging to 50 families were inventoried. In forest area, 71 plant species divided into 65 genera belonging to 32 families were inventoried. In Human modified areas, 84 plant species divided into 71 genera belonging to 27 families were inventoried. A total of 8443 betles individuals divided into 53 families were captured. Beetles are more abundant in Human modified areas but more diversified in forest. Correlation between plant diversity and beetles community showed that diversity of plant species has a positive effect, on beetles abundance and family richness in forest area. This is not the case in Human modified areas. The diversity of plant species contributes to the increase of beetles abundance and diversity in a habitat. However, Human disturbance can break this link.
