摘要
建立野生蚊子与转基因蚊子相互作用时的数量比差分方程,借助差分方程稳定性理论,获得了两类蚊子各自灭绝或共存的充要条件,并得到了两类蚊子数量比的变化趋势。
The difference equation for interaction between wild and transgenic mosquitoes is established. The necessary and sufficient conditions that those two types of mosquitoes extinct respectively or coexist with each other are obtained, and the changing tendency of ratio between their numbers is found by means of qualitative theory of difference equations.
