Implication

Review reveals direct and indirect mechanisms plant viruses use to alter host plants and insect vectors, suggesting novel targets to prevent crop epidemics.

Key Points

Examine the multifaceted direct and indirect mechanisms through which plant viruses manipulate host plants and insect vectors to maximize pathogen transmission and survival.
Synthesized literature on direct viral impacts on insect vector physiology, including olfactory modulation, epigenetic changes, salivary effectors, and horizontal gene transfer.
Reviewed indirect host-mediated pathways, such as virus-induced alterations in volatile organic compound emissions, visual cues, and plant immune defense responses.
Direct viral infection alters vector biology by modifying sensory perception, salivary components, and vector competence to promote active feeding and dispersal.
Indirect plant modifications induce attractive visual symptoms, enhance vector-attracting volatile emissions, and suppress host defenses to facilitate virus acquisition.
Intensively managed agro-ecosystems create biological and environmental conditions that amplify tripartite interactions, accelerating the spread of crop epidemics.
