摘要

背景:伊蚊,特别是埃及伊蚊和伊蚊。白纹伊蚊是登革热、寨卡病毒和基孔肯雅热等全球重大疾病的主要媒介。自2013年以来,Ae。埃及伊蚊种群在加利福尼亚迅速扩大,由于其广泛、小规模的繁殖地和对城市环境的强适应性,使控制工作变得困难。方法:遥感技术与地理信息系统(GIS)相结合,为蚊虫监测与控制提供创新解决方案。然而,了解蚊子丰富的环境驱动因素,特别是在加州多样化的生态环境中,仍然是一个重要的空白。为了解决这个差距,我们分析了Ae。埃及伊蚊丰度(2017年至2023年)与环境变量的关系,如温度、降水、地表水、海拔和建筑环境。应用热点分析方法识别蚊虫高丰度空间聚类,采用负二项分布的广义加性模型(GAM)评估环境和气象因素对蚊虫数量的影响。结果:热点分析显示伊蚊聚集;居民区附近的埃及伊蚊热点。埃及伊蚊数量随着地表水可用性和温度的升高而增加。结论:本研究揭示了伊蚊的时空动态特征。2017 - 2023年圣贝纳迪诺县西谷地区埃及伊蚊丰度,揭示环境因素和人类活动对其时间变化趋势的影响。我们的研究结果强调了温度和水的可用性在塑造蚊子种群动态中的关键作用,强调了应对环境变化的主动媒介控制策略的必要性。

Environmental correlates of Aedes aegypti abundance in the West Valley region of San Bernardino County, California, USA, from 2017 to 2023: an ecological modeling study.

Background: Aedes mosquitoes, particularly Aedes aegypti and Ae. albopictus, are major vectors of globally significant diseases such as dengue, Zika, and chikungunya. Since 2013, Ae. aegypti populations have rapidly expanded in California, making control efforts difficult due to their widespread, small-scale breeding sites and strong adaptation to urban environments.

Methods: Remote sensing technologies, coupled with Geographic Information Systems (GIS), offer innovative solutions for mosquito surveillance and control. However, understanding the environmental drivers of mosquito abundance, particularly in California's diverse ecological settings, remains an important gap. To address this gap, we analyzed Ae. aegypti abundance (2017 to 2023) in relation to environmental variables, such as temperature, precipitation, surface water, elevation, and built environment. We applied hotspot analysis to identify spatial clusters of high mosquito abundance and used a generalized additive model (GAM) with a negative binomial distribution to assess environmental and meteorological influences on mosquito counts.

Results: Hotspot analyses revealed clusters of Ae. aegypti hotspots near residential areas. Aedes aegypti counts increased with higher surface water availability and temperature.

Conclusions: Our study characterizes the spatial and temporal dynamics of Ae. aegypti mosquito abundance in the West Valley region of San Bernardino County from 2017 to 2023, shedding light on the influence of environmental factors and human activities on temporal trends. Our findings emphasize the critical role of temperature and water availability in shaping mosquito population dynamics, highlighting the need for proactive vector control strategies in response to environmental changes.

期刊介绍: Parasites & Vectors is an open access, peer-reviewed online journal dealing with the biology of parasites, parasitic diseases, intermediate hosts, vectors and vector-borne pathogens. Manuscripts published in this journal will be available to all worldwide, with no barriers to access, immediately following acceptance. However, authors retain the copyright of their material and may use it, or distribute it, as they wish. Manuscripts on all aspects of the basic and applied biology of parasites, intermediate hosts, vectors and vector-borne pathogens will be considered. In addition to the traditional and well-established areas of science in these fields, we also aim to provide a vehicle for publication of the rapidly developing resources and technology in parasite, intermediate host and vector genomics and their impacts on biological research. We are able to publish large datasets and extensive results, frequently associated with genomic and post-genomic technologies, which are not readily accommodated in traditional journals. Manuscripts addressing broader issues, for example economics, social sciences and global climate change in relation to parasites, vectors and disease control, are also welcomed.
