Diversité floristique des adventices hôtes de Achaea catocaloides Guenée : Chenille ravageuse des parcelles cacaoyères dans les départements de Toumodi et de Taabo en Côte d'Ivoire

The wild hosts of Achaea catocaloides Guenée, in the cacao crops, in the departments of Toumodi and Taabo, have been inventoried on thirty surveys in order to identify them and propose effective control strategies against this new enemy of cocoa-culture. Phytosociological studies have been conducted to achieve these objectives. At the end of this work, 61 species were identified. They can be divided into 55 genera and 32 botanical families. Euphorbiaceae and Fabaceae are the most represented families. Nineteen species have a higher frequency 80 p.c. Vines and tree species are most numerous because the agro-forestry practiced in the area. The synthesis of the results allowed proposing short-term and long-term control strategies. In the immediate future some big trees should be cut as they are the host of these insects while the long- term control strategy is essentially preventive.
