讲座内容简介:In thistalk,we propose a delay differential equationmodel to describe theWolbachiainfection dynamics in mosquitoes in which the key factor of cytoplasmic incompactibility(CI) is incorporated in a more natural way than those in the literature.By analyzing the dynamics of the model, we are able to obtain some informationon the impact of four important parameters: the competition capabilities of the wildmosquitoes and infected mosquitoes, the maternal transmission level and the CI level.The analytic results show that there are ranges of parameters that support competitionexclusion principle, and there are also ranges of parameters that allow co-persistencefor both wild and infected mosquitoes. These ranges account for the scenarios offailure of invasion, invasion and suppressing the wild mosquitoes, and invasion andreplacing the wild mosquitoes. We also discuss some possible future problems bothin mathematics and in modeling.
