Abstract

The effect of unprecedented climate change conditions on the environment has attracted the attention of experts from various disciplines who wish to predict its evolution. This is due to its interaction with population health and people's quality of life. The emergence of vector-borne diseases (VBD) in Europe, particularly caused by invasive mosquitoes, has resulted in autochthonous transmission of Dengue and Chikungunya virus cases. In this contribution, we delve into the significant decline in the population of tiger mosquitoes and the noticeable reduction in their size, related to the changes that occur often in years with low rainfall and high temperatures during the summer months. This change can be traced to the morphology of the species, which has been analysed in this work and related to the possible enhanced transmission efficiency and susceptibility of vectors to VBD dissemination. Due to the greater susceptibility to pathogen replication and subsequent transmission of the pathogens to a host during blood feeding, these morphologically distinct species relatively seem to be an efficient vector. The relationship between the sizes of studied mosquitoes and rainfall levels requires more research by mathematical epidemiologists.

气候变化与成年白纹伊蚊生理变化的相互作用

前所未有的气候变化条件对环境的影响引起了各学科专家的关注，他们希望预测气候变化的演变。这是因为气候变化与人口健康和人们的生活质量相互影响。欧洲出现的病媒传染病（VBD），尤其是由入侵蚊子引起的病媒传染病，已经导致登革热和基孔肯雅病毒病例的本土传播。在这篇论文中，我们深入探讨了虎蚊数量的显著下降及其体型的明显缩小，这与夏季降雨量低、气温高的年份经常发生的变化有关。这种变化可以追溯到物种的形态，在这项工作中对其进行了分析，这与传播效率可能提高以及病媒对 VBD 传播的敏感性有关。由于在吸血过程中更容易复制病原体并随后将病原体传播给宿主，这些形态不同的物种似乎相对是一种高效的病媒。所研究的蚊子大小与降雨量之间的关系需要数学流行病学家进行更多的研究。
