This paper looks into the stability of equilibria, existence and non-existence of traveling wave solutions in a diffusive producer-scrounger model. We find that the existence and non-existence of traveling wave solutions are determined by a minimum wave speed $c_{m}$ and a threshold value $R_{0}$. By constructing a suitable invariant convex set $Γ$ and applying Schauder fixed point theorem, the existence for $c>c_{m}, R_{0}>1$ was established. Besides, a Lyapunov function is constructed subtly to explore the asymptotic behaviors of traveling wave solutions. The non-existences of traveling wave solutions for both $c < c_{m}, R_{0}> 1$ and $R_{0}≤1, c > 0$ were obtained by two-sides Laplace transform and reduction method to absurdity.

Keywords: Diffusive producer-scrounger model, linear stability, traveling wave solution, invariant convex set, Lyapunov function.

Mathematics Subject Classification: 35K57, 92D2.
