Mosquito-borne diseases are threatening half of the world's population. To prevent the spread of malaria, dengue fever, or other mosquito-borne diseases, a new disease control strategy is to reduce or eradicate the wild mosquito population by releasing sterile mosquitoes. To study the effects of sterile insect technique on mosquito populations, we developed a mathematical model of constant release of sterile mosquitoes with strong and weak Allee effect and considered interspecific competition with mosquitoes. We calculated multiple release thresholds and investigated the dynamical behavior of this model. In order to get closer to reality, an impulsive differential equation model was also introduced to study mosquito suppression dynamics under the strategy of releasing $ c $ sterile male mosquitoes at each interval time $ T $. Finally, the relationship between the releasing amount or the waiting period and the number of days required to suppress mosquitoes was illustrated by numerical simulations.
蚊媒传染病威胁着世界一半人口的健康。为了防止疟疾、登革热或其他蚊媒传染病的传播,一种新的疾病控制策略是通过释放不育蚊子来减少或消灭野生蚊子种群。为了研究不育昆虫技术对蚊子种群的影响,我们建立了一个具有强和弱阿利效应的持续释放不育蚊子的数学模型,并考虑了与蚊子的种间竞争。我们计算了多个释放阈值,并研究了该模型的动力学行为。为了更接近实际情况,还引入了一个脉冲微分方程模型来研究在每隔时间 T 释放 c 只不育雄蚊的策略下蚊子的抑制动力学。最后,通过数值模拟说明了释放量或等待期与抑制蚊子所需天数之间的关系。
