  This paper studies the traveling wave solutions to a three species
competition cooperation system. The existence of the traveling waves is
investigated via monotone iteration method. The upper and lower solutions come
from either the waves of KPP equation or those of certain Lotka Volterra
system. We also derive the asymptotics and uniqueness of the wave solutions.
The results are then applied to a Lotka Volterra system with spatially averaged
and temporally delayed competition.
