The present work evaluates the use of species distribution model (SDM) algorithms to classify high densities of small container-breeding Aedes mosquitoes (Diptera: Culicidae) on a fine scale in the Bermuda Islands. Weekly ovitrap data collected by the Department of Health, Bermuda for the years 2006 and 2007 were used for the models. The models evaluated included the algorithms Bioclim, Domain, GARP (genetic algorithm for rule-set prediction), logistic regression and MaxEnt (maximum entropy). Models were evaluated according to performance and robustness. The area under the receiver operating characteristic curve was used to evaluate each model's performance, and robustness was assessed according to the spatial correlation between classification risks for the two datasets. Relative to the other algorithms, logistic regression was the best and MaxEnt the second best model for classifying high-risk areas. We describe the importance of covariables for these two models and discuss the utility of SDMs in vector control efforts and the potential for the development of scripts that automate the task of creating risk assessment maps.
本研究评估了物种分布模型(SDM)算法在百慕大群岛精细尺度上对高密度小型容器滋生的伊蚊(双翅目:蚊科)进行分类的应用。百慕大卫生部在2006年和2007年收集的每周诱蚊产卵器数据被用于这些模型。所评估的模型包括生物气候模型、领域模型、GARP(规则集预测遗传算法)、逻辑回归和最大熵模型。根据性能和稳健性对模型进行评估。采用受试者工作特征曲线下面积来评估每个模型的性能,并根据两个数据集分类风险之间的空间相关性评估稳健性。相对于其他算法,逻辑回归是对高风险区域进行分类的最佳模型,最大熵模型是第二好的模型。我们描述了这两个模型协变量的重要性,并讨论了物种分布模型在病媒控制工作中的效用以及开发自动创建风险评估地图任务脚本的潜力。
