报告摘要:Sterile insect technique is one of the effective biological measures in mosquitoes control. Since mosquitoes fly around as we release sterile mosquitoes, the mosquito dispersal affects the effectiveness of the releases. To study the impact of mosquito dispersal, we formulate a simple two-patch model where sterile mosquitoes are only released in one of the two patches. We establish the threshold of releases such that the wild mosquitoes are either wiped out or coexist with sterile mosquitoes. We then investigate the existence and stability of coexistent positive equilibria. Numerical examples are also provided.
