Abstract : Replanting in cocoa zones is often seen to fail in the absence of effective phytosanitary protection due to the combined effect of climate (drought) and pest attacks. For project trials, such protection is required in order to guarantee healthy development of young cocoa plants. At the same time, it is important to assess the susceptibility of cocoa cultivars to insect attacks especially the entomofauna that lives on the terminal buds of cocoa trees. Attacks can be expected even in the presence of control measures. This study is therefore applicable in all the project countries where insect attacks on young cocoa plants are frequent. Observations should be made right from planting until the canopy formation is complete (about two years after planting). (Résumé d'auteur)
