Abstract

Insect vectors play a pivotal role in the emergence and dissemination of plant viral diseases. Beyond their function in transmitting plant viruses, these insects harbor diverse insect-specific viruses (ISVs). Advances in high-throughput sequencing (HTS) have uncovered virus diversity and prevalence in insects that far exceed previous estimations. However, current knowledge of ISVs remains predominantly limited to genomic sequencing information. Investigating the fundamental biology of ISVs, their effects on insect physiology, and their modulation of vector competence is critical for deciphering complex virus-virus and virus-insect interactions. Such research holds substantial promise for developing innovative biocontrol strategies against plant viral pathogens. This review synthesizes current insights into the interplay between plant viruses and their insect vectors, explores the discovery and functional roles of ISVs, and discusses the potential application of ISVs in mitigating plant viral diseases. Understanding these dynamic relationships offers new avenues for sustainable plant disease management.

昆虫特异性病毒及其在植物病害防治中的新作用。

昆虫媒介在植物病毒性疾病的发生和传播中起着关键作用。除了传播植物病毒的功能外，这些昆虫还携带多种昆虫特异性病毒（isv）。高通量测序（HTS）的进展揭示了病毒在昆虫中的多样性和流行程度，远远超过了以前的估计。然而，目前对isv的了解仍然主要局限于基因组测序信息。研究isv的基本生物学，它们对昆虫生理的影响，以及它们对媒介能力的调节，对于破译复杂的病毒-病毒和病毒-昆虫相互作用至关重要。这些研究为开发针对植物病毒病原体的创新生物防治策略提供了巨大的希望。本文综述了植物病毒与昆虫媒介相互作用的最新研究进展，探讨了植物病毒载体的发现及其功能作用，并讨论了植物病毒载体在缓解植物病毒性疾病方面的潜在应用。了解这些动态关系为植物病害的可持续管理提供了新的途径。

期刊介绍： Viruses (ISSN 1999-4915) is an open access journal which provides an advanced forum for studies of viruses. It publishes reviews, regular research papers, communications, conference reports and short notes. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. We also encourage the publication of timely reviews and commentaries on topics of interest to the virology community and feature highlights from the virology literature in the ''News and Views'' section. Electronic files or software regarding the full details of the calculation and experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
