mosquitoes play a pivotal role as vectors of several arboviral diseases, presenting significant public health challenges worldwide. Their invasive success in tropical regions has raised substantial medical concerns. In Guatemala, mosquitoes are widely distributed and are the primary vectors of the dengue virus. Efforts to control and monitor populations have evolved over time, incorporating strategies such as spatial repellents, larvicides, genetic modifications, and targeted interventions. Previous research has shown the heterogeneous spatial-temporal distribution of these mosquitoes within each season, influenced by temperature variations and favorable environmental conditions for breeding. This study analyzed hot-spot patterns of spatiotemporal egg density in Santa Elena de la Cruz, Petén, Guatemala, from March to September 2022. The aim was to determine whether these patterns were influenced by non-residential larval habitats with plant cover that are not treated by healthcare entities, as well as the proximity between such habitats. Our findings include the collection and registration of over 16,000 eggs during the study period. Local analyses revealed hot-spot patterns in egg densities associated with non-residential larval habitats and their proximity. These insights highlight critical focal points where targeted interventions could be implemented more effectively, resulting in cost-efficient mosquito vector control.
蚊子作为多种虫媒病毒疾病的传播媒介发挥着关键作用,在全球范围内带来了重大的公共卫生挑战。它们在热带地区的入侵式成功引发了大量医学关注。在危地马拉,蚊子分布广泛,是登革热病毒的主要传播媒介。随着时间推移,控制和监测蚊子种群的努力不断发展,纳入了诸如空间驱避剂、杀幼虫剂、基因改造和靶向干预等策略。先前的研究表明,受温度变化和适宜繁殖环境条件影响,这些蚊子在每个季节内呈现出时空分布的异质性。本研究分析了2022年3月至9月危地马拉佩滕省圣埃伦娜·德拉克鲁兹时空卵密度的热点模式。目的是确定这些模式是否受到医疗保健机构未处理的有植物覆盖的非住宅幼虫栖息地以及此类栖息地之间距离的影响。我们的研究结果包括在研究期间收集并记录了超过16000枚卵。局部分析揭示了与非住宅幼虫栖息地及其距离相关的卵密度热点模式。这些见解突出了可以更有效实施靶向干预的关键焦点,从而实现具有成本效益的蚊媒控制。
