Résumé : 

• CONTEXT: Cocoa swollen shoot virus (CSSV) remains the most destructive viral disease affecting cocoa in West Africa, with ecological and economic repercussions. Since the virus is specialized to cocoa and disperse locally through mealybugs vectors, landscape structure could play a crucial role in determining epidemic outcomes.
• OBJECTIVES: This study aimed to assess how landscape structure influences CSSV spread and economic returns, to identify landscape structures that reconcile epidemiological control with profitability.
