- In this study, we investigate a prey-predator model exhibiting Holling type-III functional response among mutually interfering predators to assess the effects of provision of additional food to natural enemies in altering pest dynamics. We derive and study both the non-additional food provided system (initial system) and additional food provided system mathematically and through extensive numerical simulations. We prove the positivity and boundedness of the solutions of both the systems. We perform an extensive existence and stability analysis of various equilibrium points exhibited by both the systems. We discuss the global dynamics and stability behavior exhibited by both the systems with respect to crucial parameters using numerical methods. Considering the quality and quantity of additional food as control parameters, we framed and characterized the time optimal control problems. We further simulated these time optimal problems using numerical optimization techniques. Our theoretical and numerical investigations reveal that the provision of suitable choice of additional food steers the system to a prey-elimination state, leading to a pest-regulated ecosystems.
