In order to study the abundance and diversity of beetlesinrubberagro systems, a study was conducted in Bongo and Toupahrespectively in the south and south-east of Côted'Ivoire. Beetle were sampled by the combination off our types of traps in different plantations aged from1to 5,6 to10 years, overthan 15 years old, and a forest as control. A total of 10874 beetles distributed in 55 families were collected. The distribution of beetles families in different groups according to their size, shows that abundant Beetle have a higher abundance than the common and rare ones. However, the latter are richer in families. The forests in the two localities have higher numbers of beetles.However, the values of the Shannon (H) diversity index do not differ from one habitat to another in the two study areas. Yet, beetles are better distributed in the plantations in production with a high equitability index (E) in Toupah and Bongo. This study has shown that rubber cultivation, despite the strong anthropic activities related to latex production, does not affect the diversity of beetle’s families.
