| contents | We delve into the interactions between a prey-predator and a vector-borne epidemic system, driven by agro-ecological motivations. This system involves an ODE, two reaction--diffusion PDEs and one reaction--diffusion--advection PDE. It has no complete variational or monotonic structure and features spatially heterogeneous coefficients. Our initial focus is to examine the continuity of a quantity known as ''harvest'', which depends on the time-integral of infected vectors. We analyze its asymptotic behaviour as the domain becomes homogeneous. Then we tackle a non-standard optimal control problem related to the linearized harvest and conduct an analysis to establish the existence, uniqueness, and properties of optimizers. Finally, we refine the location of optimizers under specific initial conditions. |
