摘要

沙蝇是利什曼原虫的主要媒介,在巴尔干及其邻近地区广泛流行。在众多因素中,气象限制因素影响了沙蝇的分布和活动,因此对评估了解沙蝇的发生和预防病原体传播具有重要意义。为了确定东南欧地区沙蝇的日活动极限,我们使用了来自7个国家的8种昆虫捕获数据,以及E-OBS网格数据集的温度、降水、全球辐射、风速和海平面压力数据。91.3%的分析地点为湿润亚热带-大陆生态型,但物种间的气象活动阈值存在异质性。根据其气象极限对物种进行排序,balcanicus和papatasi Ph.具有最广泛的一般气象耐受性,而minuta Sergentomyia、tobbi Ph.和simici Ph.对气象变化最敏感。主坐标分析结果表明,与活动约束相关的生态位范围最广的是忽略和mascittii,最小的是tobbi和simici。乳突白蛉和乳突白蛉。米努塔在活动的气象要求方面表现出最显著的总体差异。集合试验表明,不同沙蝇种类对不同气象因子的特征重要性与其活动有关。这项研究将有助于更好地了解东南欧地区沙蝇发生的小规模差异,为未来的调查和有针对性的监测提供支持,以评估流行地区的病原体传播。

Climatic and meteorological factors shaping the potential activity season of sand flies in Southeast Europe
Sand flies, the principal vectors of Leishmania spp., are widely endemic in the Balkans and its neighbouring area. Among many factors, meteorological constraints shape sand fly distribution and activity, and are therefore important to assess to understand sand fly occurrence and prevent transmission of pathogens. To determine the daily limits of sand fly activity in Southeast Europe, we used entomological trapping data of eight species from seven countries, as well as temperature, precipitation, global radiation, wind speed, and sea level pressure data of the E-OBS gridded dataset. While 91.3 % of analyzed sites represented humid subtropical-continental ecotypes, heterogenous meteorological activity thresholds were found between species. By ranking the species based on their meteorological limits, Phlebotomus balcanicus and Ph. papatasi showed the widest general meteorological tolerance, whereas the activity of Sergentomyia minuta, Ph. tobbi, and Ph. simici were observed to be most sensitive to meteorological changes. However, principal ordinate analysis suggested that Ph. neglectus and Ph. mascittii had the widest ecological niches related to their activity constraints, and Ph. tobbi and Ph. simici had the narrowest. Phlebotomus mascitti and Se. minuta exhibited the most notable overall dissimilarity of the meteorological requirements of activity. The ensemble tests showed that the feature importance of different meteorological factors varies by sand fly species related to their activity. This study should help to better understand small-scale differences in sand fly occurrence in Southeast Europe to support future surveys and targeted surveillance to assess pathogen transmission in endemic areas.
