Modelo Entomológico Determinístico sob Efeito da Pluviosidade para o Aedes aegypti e o Aedes albopictus

ABSTRACT The mosquito species Aedes aegypti and Aedes albopictus are prominent in the dispersal of several arboviruses, among them: dengue fever, yellow fever, chikungunya fever and zika virus. Recent works in the area of mathematical biology have been carried out in order to describe the dynamics of the population of these vectors and, consequently, to help public managers in the control of these arboviruses. In this work, we present an entomological model to describe the life cycle of those species of mosquitoes. The coefficients of the model are fixed as rainfall dependent. The results of the model are validated by comparison to field data of captures of females A. aegypti performed in the cities of Caratinga and Sete Lagoas, Minas Gerais, Brazil.

摘要 埃及伊蚊（Aedes aegypti）与白纹伊蚊（Aedes albopictus）是多种虫媒病毒（arboviruses）的重要传播媒介，所传播的病毒包括登革热、黄热病、基孔肯雅热以及寨卡病毒（zika virus）。数学生物学领域近期已开展多项相关研究，旨在刻画这类病媒种群的动态变化，进而助力公共卫生管理者开展此类虫媒病毒的防控工作。本研究构建了一款昆虫学模型（entomological model），用于描述上述两种蚊虫的生命周期；模型系数被设定为依赖降雨量的参数。通过与巴西米纳斯吉拉斯州卡拉廷加市（Caratinga）与塞特拉戈阿斯市（Sete Lagoas）开展的埃及伊蚊雌蚊野外捕获数据进行对比，本研究验证了该模型的结果有效性。
