Thrips are key vectors for plant viruses, representing a significant challenge to the cultivation of cucurbits and other vegetables in tropical agriculture. This study investigates the diversity of viromes carried by thrips and their ecological roles in viral epidemics affecting specific crops.
We identify thrips populations in tropical regions and perform a comprehensive virome analysis through high-throughput sequencing.
Our findings reveal that the predominant thrips species associated with these crops are , , and . The sequencing efforts identified 19 viruses within these thrips, including previously undocumented viruses, such as a double-stranded RNA virus and several positive- and negative-sense single-stranded RNA viruses. Notably, detection rates of specific plant viruses-Melon yellow spot virus (MYSV), Watermelon silver mottle virus (WSMoV), and Telosma mosaic virus (TeMV)-exhibit significant correlations with thrips population density in cucurbits and other vegetables.
This study lays the groundwork for future research into the ecological relationships between thrips and plant viruses, offering valuable insights for developing targeted disease management strategies in tropical agricultural systems.
蓟马是植物病毒的关键传播媒介，对热带农业中葫芦科作物和其他蔬菜的种植构成重大挑战。本研究调查了蓟马携带的病毒群落多样性及其在影响特定作物的病毒流行中的生态作用。
我们确定了热带地区的蓟马种群，并通过高通量测序进行了全面的病毒群落分析。
我们的研究结果表明，与这些作物相关的主要蓟马种类是 、 和 。测序工作在这些蓟马体内鉴定出19种病毒，包括以前未记录的病毒，如一种双链RNA病毒以及几种正链和负链单链RNA病毒。值得注意的是，特定植物病毒——甜瓜黄斑病毒（MYSV）、西瓜银斑驳病毒（WSMoV）和夜来香花叶病毒（TeMV）的检出率与葫芦科作物和其他蔬菜中蓟马的种群密度呈现出显著相关性。
本研究为未来研究蓟马与植物病毒之间的生态关系奠定了基础，为在热带农业系统中制定针对性的病害管理策略提供了有价值的见解。
