摘要

摘要本文建立了一个具有周期参数的离散模型来描述循环环境下沃尔巴克氏体在蚊虫种群中的传播动态。这项工作修改了现有文献中建立的模型，这些模型没有考虑到由于季节性和其他因素引起的环境周期性变化的参数变化。当模型中的参数为常数时，已经得到了广泛的研究和应用。我们给出了一个值得进一步研究的关于最多存在两个周期解的猜想，并证明了该猜想对于2周期参数的特殊情况是成立的。数值模拟也说明了周期性现象的发生。关键词:蚊媒疾病沃尔巴克氏体非自主离散模型周期解循环环境smsc (2020):: 92B0592D3037N25披露声明作者未报告潜在利益冲突。基金资助:国家自然科学基金项目(no . 11971127, 12331017, 12071095, 12371484)。

Wolbachia spread dynamics in mosquito populations in cyclic environments

AbstractIn this paper, we establish a discrete model with periodic parameters to depict the Wolbachia spread dynamics in mosquito populations in cyclic environments. This work modifies the models established in the existing literature that did not take into account the variation of parameters with environmental periodic changes due to seasonality and other factors. When the parameters in our model are constants, it has been extensively studied and widely used. We present a conjecture about the existence of at most two periodic solutions worthy of further study, and show that the conjecture is true for the special case of 2-periodic parameters. Numerical simulations are also provided to illustrate the occurrence of periodic phenomena.Keywords: Mosquito-borne diseasesWolbachianon-autonomous discrete modelperiodic solutionscyclic environmentsMSC(2020):: 92B0592D3037N25 Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingThis work was supported by National Natural Science Foundation of China (Nos: 11971127, 12331017, 12071095, 12371484).

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
