We undertook geometric morphometric analysis of wing venation to assess this character's ability to distinguish Anopheles darlingi Root populations and to test the hypothesis that populations from coastal areas of the Brazilian Atlantic Forest differ from those of the interior Atlantic Forest, Cerrado, and the regions South and North of the Amazon River. Results suggest that populations from the coastal and interior Atlantic Forest are more similar to each other than to any of the other regional populations. Notably, the Cerrado population was more similar to that from north of the Amazon River than to that collected of south of the River, thus showing no correlation with geographical distances. We hypothesize that environmental and ecological factors may affect wing evolution in An. darlingi. Although it is premature to associate environmental and ecological determinants with wing features and evolution of the species, investigations on this field are promising.
我们进行了翅膀脉序的几何形态测量分析，以评估该特征区分致倦库蚊罗氏亚种种群的能力，并检验以下假设，即来自巴西大西洋森林沿海地区的种群与来自内陆大西洋森林、塞拉多以及亚马孙河南北地区的种群不同。结果表明，来自沿海和内陆大西洋森林的种群彼此之间比与其他任何地区的种群更为相似。值得注意的是，塞拉多种群与亚马孙河北部的种群更为相似，而与亚马孙河南部的种群不相似，因此与地理距离无关。我们假设环境和生态因素可能会影响致倦库蚊罗氏亚种翅膀的进化。尽管将环境和生态决定因素与翅膀特征以及物种的进化联系起来还为时过早，但该领域的研究很有前景。
