摘要

蚊子传播的疾病对全球公共卫生构成重大挑战。我们的研究重点是泰国天那色林(又称塔那斯里)森林连接地区蚊子物种的季节多样性。此外,我们还采用几何形态计量学技术评估了五种主要蚊子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,包括 8 个属 42 个种。在这些森林连接区,辛普森指数和香农物种多样性指数分别为 0.86 和 2.36,表明蚊子的多样性水平很高。我们使用相似性分析(ANOSIM)测试进行的分析表明,蚊子群落存在显著的季节性差异,下连接区的 R 值为 0.30(p < 0.05),上连接区的 R 值为 0.37(p < 0.05)。此外,典型对应分析表明,每种蚊子的数量都受到各种气候因素的影响。对翅膀大小和形状的表型分析加深了我们对当地适应性和影响这些病媒的季节性压力的理解。值得注意的是,与其他季节相比,大多数物种在旱季表现出更大的翅膀尺寸。此外,对五种主要蚊子翅膀形状的季节性评估显示,不同季节的种群之间存在显著差异(p < 0.05)。对这些蚊子种群的持续监测对于加深我们对季节对蚊子数量和生理适应性的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。

Investigating the impact of climate and seasonality on mosquito (Diptera: Culicidae) vector populations in the connecting areas of the Tenasserim range forests in Thailand

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.
