• A two-dimensional stage-structured model for the interactive wild and sterile mosquitoes is derived where the wild mosquito population is composed of larvae and adult classes and only sexually active sterile mosquitoes are included as a function given in advance. The strategy of constant releases of sterile mosquitoes is considered but periodic and impulsive releases are more focused on. Local stability of the origin and the existence of a positive periodic solution are investigated. While mathematical analysis is more challenging, numerical examples demonstrate that the model dynamics, determined by thresholds of the release amount and the release waiting period, essentially match the dynamics of the alike one-dimensional models. It is also shown that richer dynamics are exhibited from the two-dimensional stage-structured model.

Figure 4.  Parameters are given in (23) and the release amount threshold $c^* = 4.35979$. With $c = 3 < c^*$, the threshold waiting period threshold $T^*$ seems between 6 and 7. When $T = 6$, the origin is locally, not globally, asymptotically stable and there exists a locally asymptotically stable positive periodic solution as shown in the left figure. When $T = 7$, there exists a globally asymptotically stable positive periodic solution as shown in the right figure. Here only the solution curves for the larvae are presented

Figure 5.  Parameters are still given in (23) with the same release amount threshold $c^* = 4.35979$, but now $c = 6 > c^*$. When $T = 5.5$, the origin is globally asymptotically stable as shown in the left figure, and when $T = 7$ there exists a globally asymptotically stable positive periodic solution as shown in the right figure. Here again only the solution curves for the larvae are presented

Figure 6.  With the same parameters in (23), and also the same $c = 6 > c^* = 4.35979$ when $T = 6$, the origin is only locally asymptotically stable and there exists a locally asymptotically stable positive periodic solution
