Abstract: Intraguild predation (IGP) is widespread in nature. In this paper, a mathematical model of a tri-trophic food web with IGP and prey switching is considered, where the IG predator tends to consume disproportionately more of the relatively abundant prey. Bifurcation analysis shows that prey switching may (i) enhance the persistence of the IG prey when it is an inferior competitor for resources; (ii) enhance the persistence of the IG predator when one of the prey species is at least moderately abundant; (iii) facilitate coexistence of all species; and (iv) stabilize the population dynamics. It has been found that prey switching combined with predator interference may have a synergistic effect on enhancing coexistence and stabilizing population dynamics. Bistability and chaotic attractors are also observed in the mathematical model for a small range of parameter values.
