The study on termite attack patterns and biogenic structures produced in cocoa farms of different ages was conducted in the Oumé region (former cocoa loop). Thus, eight kinds of termites belonging to two trophic groups (Fungus-grow and xylophagous) are particularly harmful on the cocoa tree: Ancistrotermes, Coptotermes, Microtermes, Microcerotermes, Nasutitermes, Neotermes and Schedorhinotermes. Fungus-grow termites insert clay soil under the bark, which causes it to be stripped in the presence of the sun. On the other hand, xylophagous establish crop tunnels in the plant made of chewed sawdust of different hues according to the genera. In this group, only Neotermes does not construct veneers of external crops. It has direct access to the plant by undoubtedly perforating the secondary roots and invading the whole plant. Their presence is characterized by the walls of galleries in "necrotic" form.
