Dengue hemorrhagic fever and Rift Valley fever are the most important mosquitoborne diseases in the Kingdom of Saudi Arabia. The characteristic habitat requirements of Stegomyia aegypti and Culex tritaeniorhynchus, the two mosquito vectors will help in the identification of "high risk" areas in their development. Species distribution modelling was assessed by using MaxEnt software combined with geographical information systems (GIS) to predict suitable larval habitats for these two vectors and develop potential risk maps that can be used for their targeted control. Climate and topographical data layers from Worldclim and larval occurrence records were used to model these two vectors. The results showed that suitable habitats of St. aegypti are widely distributed only in the central region and Cx. tritaeniorhynchus were in the central and southwestern parts of Al-Bahah Province. The highest predictive power was shown by topographical variables in St. aegypti modeling and the minor contributions were shown by precipitation and temperature related variables. The maximum contribution was shown by temperature related variables and minor contribution was shown by topographical and precipitation related variables in Cx. tritaeniorhynchus modeling. Linear regression model indicates non significant correlation between TDS/pH and species abundance of these two mosquitoes.
登革出血热和裂谷热是沙特阿拉伯王国最重要的蚊媒疾病。埃及伊蚊和三带喙库蚊这两种蚊媒的特定栖息地要求，将有助于识别其繁殖过程中的“高风险”区域。利用最大熵（MaxEnt）软件结合地理信息系统（GIS）评估物种分布模型，以预测这两种蚊媒适宜的幼虫栖息地，并绘制潜在风险地图，用于针对性防控。利用来自世界气候数据库（Worldclim）的气候和地形数据图层以及幼虫出现记录，对这两种蚊媒进行建模。结果显示，埃及伊蚊适宜的栖息地仅广泛分布于中部地区，而三带喙库蚊的适宜栖息地位于巴哈省的中部和西南部。在埃及伊蚊建模中，地形变量显示出最高的预测能力，而与降水和温度相关的变量贡献较小。在三带喙库蚊建模中，与温度相关的变量贡献最大，而与地形和降水相关的变量贡献较小。线性回归模型表明，总溶解固体/酸碱度（TDS/pH）与这两种蚊子的物种丰度之间无显著相关性。
