Abstract:
This article presents a new eco-epidemiological deterministic delay differential
equation model considering a biological controlling approach on mosquitoes,
for endemic dengue disease with variable host (human) and variable vector
(Aedes aegypti) populations, and stage structure for mosquitoes.
In this model, predator-prey interaction is considered by using larvae
as prey and mosquito-fish as predator. We give a complete classification of
equilibria of the model, and sufficient conditions for global stability/global
attractivity of some equilibria are given by constructing suitable Lyapunov
functionals and using Lyapunov-LaSalle invariance principle.
Also, numerical simulations are presented to show the validity of our results.
