Abstract:To more effectively control mosquitoes, a modified genetic sterile insect technique (SIT) is used and strategies of releasing mosquitoes carrying a dominant lethal (RIDL) are proposed and developed. There are four strategies implemented, including early acting bisex (EBS) lethality, late acting bisex (LBS) lethality, early acting female-killing (EFK) lethality, and late acting female-killing (EFK) lethality. In this talk, we introduce homogeneous mosquito population models based on different differential equations and incorporate the four transgenic SIT implementations in the models, respectively. We show the model dynamics and define release thresholds of the sterile mosquitoes for all the implementations to determine whether wild mosquitoes can be eradicated or coexist with the sterile mosquitoes. We discuss our findings and compare the different release strategies with numerical examples.
