Mosquito females of the genus (Blanchard) can be a nuisance to humans and animals since they are voraciously hematophagous and feed on the blood of a variety of vertebrates. Despite their relevance, there is a lack of investigation into the blood-feeding patterns of the species. Knowledge of the host preference is crucial in establishing the public health importance of a mosquito species and its potential to be involved in the transmission dynamics of pathogens. Species that are primarily anthropophilic can be more effective in spreading vector-borne pathogens to humans. In this study, we used an Illumina Nextera sequencing protocol and the QIIME2 workflow to assess the diversity of DNA sequences extracted in the ingested blood of mosquito species to evaluate the overall and local host choices for three species: , Amazonensis, and , in rural areas alongside the Madeira River in the vicinities of the Santo Antonio Energia (SAE) reservoir in the municipality of Porto Velho, Rondônia, Western Brazil. By performing our analysis pipeline, we have found that host diversity per collection site showed a significant heterogeneity across the sample sites. In addition, in rural areas, present a high affinity for , shows an overall preference for and , but also and in urban areas, and showed more opportunistic behavior in rural areas, feeding on wild animals and , though with an overall preference for .
(布兰查德)属的雌性蚊子会对人类和动物造成滋扰,因为它们非常嗜血,以各种脊椎动物的血液为食。尽管它们很重要,但对 物种的吸血模式的研究还很缺乏。了解宿主偏好对于确定蚊子物种的公共卫生重要性及其在病原体传播动态中的潜在作用至关重要。主要嗜人的物种可以更有效地将媒介传播的病原体传播给人类。在这项研究中,我们使用 Illumina Nextera 测序方案和 QIIME2 工作流程来评估从蚊子物种摄入的血液中提取的 DNA 序列的多样性,以评估三种物种( 、 Amazonensis 和 )的总体和局部宿主选择,这些物种位于巴西朗多尼亚州圣安东尼奥能源(SAE)水库附近的马德拉河沿线的若昂佩索阿市的农村地区。通过执行我们的分析管道,我们发现每个采集点的宿主多样性在样本点之间表现出显著的异质性。此外,在农村地区, 对 表现出高度亲和力, 总体上偏爱 ,但也偏爱 和 在城市地区, 在农村地区表现出更多的机会主义行为,以野生动物和 为食,但总体上偏爱 。
