报告摘要：Mosquito-borne diseases such as dengue fever and Zika kill more than700, 000people each year in the world.A novel strategy formosquito-borne disease control uses the bacterium Wolbachia to block virus transmission. It requires releasing Wolbachia-infected mosquitoes to exceed a threshold level. Since an accurate forecast for temperature and rainfall, the major environmental conditions regulating the mosquito dynamics, is often not available over a long time period, it is important to explore how the threshold releasing level changes in random environments.By comparing the dynamics between the stochastic system and constructed auxiliary systems, combined with other techniques, we provide sharp estimates on the threshold releasing level for Wolbachia fixation.In addition, we prove that the threshold level is,surprisingly, defined by a deterministic curve that does not fluctuate with environmentalconditions.
