了解疟疾传播背后蚊子种群的时间动态是优化控制策略的关键。我们整理了印度117个地点40年来的蚊子时间序列捕获数据，以了解驱动这些动态的因素。我们的分析揭示了不同地点和物种之间的动态变化。许多蚊子种群缺乏通常假设的与降雨的正相关关系，相反，显示出与降水只有微弱甚至负相关的丰度模式，并突出了温度、与多年生水体的接近程度和土地利用模式在塑造蚊子种群动态和季节性方面的作用。我们表明，这些不同的动态可以聚集成“动态原型”，每个原型都有不同的时间特性，并由一组很大程度上独特的环境因素驱动。这些结果强调了多种因素的复杂相互作用，而不仅仅是降雨，决定了蚊子种群季节性的时间和程度。
Understanding the temporal dynamics of mosquito populations underlying malaria transmission is key to optimising control strategies. We collate mosquito time-series catch data spanning 40 years and 117 locations across India to understand the factors driving these dynamics. Our analyses reveal pronounced variation in dynamics across locations and between species. Many mosquito populations lacked the often-assumed positive relationship with rainfall, instead displaying patterns of abundance that were only weakly or even negatively correlated with precipitation and highlighting the role of temperature, proximity to perennial bodies of water and patterns of land use in shaping the dynamics and seasonality of mosquito populations. We show that these diverse dynamics can be clustered into “dynamical archetypes”, each characterised by distinct temporal properties and driven by a largely unique set of environmental factors. These results highlight that a complex interplay of factors, rather than rainfall alone, shape the timing and extent of mosquito population seasonality.
