Mosquito species belonging to the genus Aedes have attracted the interest of scientists and public health officers because of their capacity to transmit viruses that affect humans. Some of these species were brought outside their native range by means of trade and tourism and then colonised new regions thanks to a unique combination of eco-physiological traits. Considering mosquito physiological and behavioural traits to understand and predict their population dynamics is thus a crucial step in developing strategies to mitigate the local densities of invasive Aedes populations. Here, we synthesised the life cycle of four invasive Aedes species (Ae. aegypti, Ae. albopictus, Ae. japonicus and Ae. koreicus) in a single multi-scale stochastic modelling framework which we coded in the R package dynamAedes. We designed a stage-based and time-discrete stochastic model driven by temperature, photo-period and inter-specific larval competition that can be applied to three different spatial scales: punctual, local and regional. These spatial scales consider different degrees of spatial complexity and data availability by accounting for both active and passive dispersal of mosquito species as well as for the heterogeneity of the input temperature data. Our overarching aim was to provide a flexible, open-source and user-friendly tool rooted in the most updated knowledge on the species' biology which could be applied to the management of invasive Aedes populations as well as to more theoretical ecological inquiries.
属蚊种因其传播影响人类的病毒能力而引起了科学家和公共卫生官员的关注。这些物种中的一些是通过贸易和旅游从其原生范围带到外面的，然后由于独特的生态生理特征组合而在新的地区殖民化。因此，考虑蚊子的生理和行为特征来理解和预测其种群动态是制定减轻入侵埃及伊蚊种群局部密度的策略的关键步骤。在这里，我们在一个单一的多尺度随机建模框架中综合了四种入侵埃及伊蚊（埃及伊蚊、白纹伊蚊、日本伊蚊和朝鲜伊蚊）的生命周期，我们在 R 包 dynamAedes 中对其进行了编码。我们设计了一个基于阶段和时间离散的随机模型，由温度、光周期和种间幼虫竞争驱动，可应用于三个不同的空间尺度：点状、局部和区域。这些空间尺度考虑了不同程度的空间复杂性和数据可用性，既考虑了蚊子物种的主动和被动扩散，也考虑了输入温度数据的异质性。我们的总体目标是提供一个灵活的、开源的和用户友好的工具，该工具根植于对物种生物学的最新知识，可以应用于入侵埃及伊蚊种群的管理以及更具理论性的生态研究。
