The coconut tree is often mentioned as the “tree of life” due to its immense benefits to the human community ranging from edible products to building materials. Rugose spiraling whitefly (RSW), a natural enemy seems to be a major threat to farmers in bringing up these coconut trees. A mathematical model to study the dynamics of pest population in the presence of predator and parasite is developed. The biologically feasible equilibrium points are derived. Local asymptotic stability as well as global asymptotic stability is analyzed at the points. Furthermore, in order to educate farmers on pest control, we have added the impact of awareness programs in the model. The conditions of existence and stability properties of all feasible steady states of this model are analyzed. The result reveals that predator and parasite play a major role in reducing the immature pest. It also shows that pest control activities through awareness programs further reduce the mature pest population which decreases the egg laying rate which in turn reduces the immature population.
