Résumé
We develop a nonlinear host–vector model to describe the transmission dynamics of Tomato Yellow Leaf Curl Virus (TYLCV) in tomato crops. The model couples an SEIR structure for the plant population with an SI formulation for the vector Bemisia tabaci, incorporating logistic growth and saturated incidence functions
