Mosquito-borne diseases pose a significant public health challenge globally. Our study focused on the seasonal diversity of mosquito species in the connecting areas of the Tenasserim (also known as Tanaosri) range forests in Thailand. Additionally, we employed the geometric morphometric technique to assess variations in wing size and shape among five predominant mosquito species. Throughout the study period, we collected a total of 9,522 mosquitoes, encompassing 42 species across eight genera. In these connecting areas of forests, the Simpson index and Shannon species diversity index were recorded at 0.86 and 2.36, respectively, indicating a high level of mosquito diversity. Our analysis using the Analysis of Similarities (ANOSIM) test showed significant seasonal differences in mosquito communities, with an R-value of 0.30 (p < 0.05) in the lower connecting areas and 0.37 (p < 0.05) in the upper connecting areas. Additionally, canonical correspondence analyses showed that the abundance of each mosquito species is influenced by various climate factors. Phenotypic analyses of wing size and shape have deepened our understanding of local adaptation and the seasonal pressures impacting these vectors. Notably, most species exhibited larger wing sizes in the dry season compared to other seasons. Additionally, seasonal assessments of wing shape in five predominant mosquito species revealed significant differences across seasonal populations (p < 0.05). Ongoing monitoring of these populations is crucial to enhancing our understanding of the seasonal effects on mosquito abundance and physiological adaptations. These insights are essential for developing more effective strategies to manage mosquito-borne diseases.
蚊媒疾病在全球范围内构成重大公共卫生挑战。我们的研究聚焦于泰国丹那沙林山脉（也称为塔那梭里）连接地区的蚊种季节性多样性。此外，我们采用几何形态测量技术评估了五种主要蚊种的翅膀大小和形状的变化。在整个研究期间，我们共收集了 9522 只蚊子，涵盖了 8 个属的 42 个种。在这些森林连接地区，辛普森指数和香农物种多样性指数分别为 0.86 和 2.36，表明蚊种多样性很高。我们使用相似性分析（ANOSIM）检验分析蚊群的季节性差异，结果显示在下部连接区的 R 值为 0.30（p<0.05），在上部连接区的 R 值为 0.37（p<0.05）。此外，典范对应分析表明，每种蚊子的丰度受多种气候因素的影响。翅膀大小和形状的表型分析加深了我们对本地适应和影响这些媒介季节性压力的理解。值得注意的是，与其他季节相比，大多数物种在旱季具有更大的翅膀尺寸。此外，对五种主要蚊种的翅膀形状进行季节性评估显示，季节性种群之间存在显著差异（p<0.05）。对这些种群进行持续监测对于增强我们对蚊子丰度和生理适应季节性影响的理解至关重要。这些见解对于制定更有效的蚊媒疾病管理策略至关重要。
