Dynamical behavior of a mosquito population suppression model composed of two sub-models
Abstract
In this paper, a new mosquito population suppression model with stage and sex structure is constructed, which is composed of two sub-models switching each other. Sterile mosquitoes are released with period T and remain sexually active for time ˉT. For the case ˉT<T, three thresholds T∗,m∗ and c∗ are determined for the release period T and release amount c. According to the values of T and c in different ranges determined by these thresholds, we study the dynamical behavior of the system for different release strategies, mainly including the existence and stability of the mosquito-extinction equilibrium and positive periodic solutions. Finally, some numerical simulations are performed to illustrate our results.
