报告摘要：There is currently great interest in releasing Wolbachia-infected Aedes mosquitoes to mitigate arbovirus transmission around the world. Wolbachia infection in Aedes mosquitoes may block the replication of RNA viruses, under both laboratory and field conditions. For Wolbachia establishment in natural field populations, the key information is the minimum number of Wolbachia-infected mosquitoes released which determines whether the release will be logistically and economically feasible. In existing literature, mathematical models characterized the minimum introduction threshold in terms of the maternal leakage rate μ, the CI intensity s_h, and the fitness cost s_f. These results are good enough for cage experiments. However, regarding the Wolbachia dynamics in field settings and across seasons, these parameters are not constants anymore, which depend on environmental conditions instead. I’d like to introduce a generalized model in this talk. The model covers the existing discrete models as a special case, and it generates a unique periodic solution in periodic environmental conditions.
