Plant chemicals mediating interactions with insect herbivores seem a likely target for manipulation by insect-vectored plant pathogens. Yet, little is currently known about the chemical ecology of insect-vectored diseases or their effects on the ecology of vector and non-vector insects. We recently reported that a widespread plant pathogen, Cucumber mosaic virus (CMV), greatly reduces the quality of host-plants (squash) for aphid vectors, but that aphids are nevertheless attracted to the odors… 
Reciprocal plant-mediated interactions between a virus and a non-vector herbivore.
Evaluating reciprocal interactions between Pea enation mosaic virus (PEMV), a pathogen transmitted by the aphid Acrythosiphon pisum, and a non-vector weevil, Sitona lineatus highlights the importance of non- vector species in influencing plant pathogens and their vectors through host-mediated effects.
Virus strains differentially induce plant susceptibility to aphid vectors and chewing herbivores
It is proposed that pathogens chemically mediate insect–plant interactions by activating the salicylate pathway and decreasing plant resistance to chewing insects, which has implications for both disease transmission and insect community structure.
Manipulation of Jasmonate Signaling by Plant Viruses and Their Insect Vectors
The roles of JA signaling in the tripartite interactions among plant, virus, and insect vectors are reviewed, with a focus on the molecular and biochemical mechanisms that drive vector-borne plant viral diseases.
Chemical Ecology of Aphid-Transmitted Plant Viruses
In this chapter, a chemical ecology of vector-transmitted plant viruses must be indirect, resulting from the effects of virus infection on the host plants and the responses to these changes by vectors and other organisms in the ecological community.
Plant feeding by insect vectors can affect life cycle, population genetics and evolution of plant viruses
This review focuses on presenting unforeseen aspects related to (i) the impacts that the feeding habits of different insect vectors can have on the evolution of plant viruses and (ii) the possibility that vector-related stresses induce major switches in the ‘behaviour' of viruses in planta, affecting primarily the efficiency of transmission by insect vectors.
Virus Infection of Plants Alters Pollinator Preference: A Payback for Susceptible Hosts?
It is speculated that enhanced pollinator service for infected individuals in wild plant populations might provide mutual benefits to the virus and its susceptible hosts.
Manipulation of Vector Host Preference by Pathogens: Implications for Virus Spread and Disease Management
The effects of vector manipulation on crop yield loss to disease and on the economic returns for vector suppression are explored and a framework that can inform management decisions is provided.
Insect-Borne Plant Pathogens and Their Vectors: Ecology, Evolution, and Complex Interactions.
A proposed research agenda includes examining vector manipulation syndromes comprehensively within pathosystems, expanding the taxonomic and genetic breadth of the systems studied, evaluating dynamic effects that occur during disease progression, incorporating the influence of biotic and abiotic environmental factors, evaluating the effectiveness of putative manipulation Syndromes under field conditions, and deciphering chemical and molecular mechanisms whereby pathogens can influence vectors.
The genus Luteovirus from infection to disease
This review summarizes the current understanding of disease epidemiology and reviews the current literature encompassing viral infectivity, economic impact and control measures.


Deceptive chemical signals induced by a plant virus attract insect vectors to inferior hosts
CMV appears to attract vectors deceptively to infected plants from which they then disperse rapidly, a pattern highly conducive to the nonpersistent transmission mechanism employed by CMV and very different from the pattern previously reported for persistently transmitted viruses that require sustained aphid feeding for transmission.
Herbivore arthropods benefit from vectoring plant-viruses
It is proposed that plant pathogens in general have evolved mechanisms to overcome plant defences against their vectors, thus promoting pathogen spread.
Do Plant Viruses Facilitate Their Aphid Vectors by Inducing Symptoms that Alter Behavior and Performance?
In this system, the attractiveness of an infected host plant and its quality in terms of aphid growth and reproduction were not related to the pathogen’s dependence on the aphid for transmission to new hosts.
Antagonistic Effects of Soybean Viruses on Soybean Aphid Performance
A series of field and laboratory experiments examined how infection of soybeans with the common plant viruses, alfalfa mosaic, soybean mosaic, and bean pod mottle viruses influenced soybean aphid performance.

This review examines empirical, experimental, and field-based evidence to evaluate examples of changes in vector behavior and physiology that might be construed to be manipulative.
Lack of Effect of Tobacco Mosaic Virus-Induced Systemic Acquired Resistance on Arthropod Herbivores in Tobacco
It is found that inoculation of the lower leaves of tobacco with tobacco mosaic virus had no effect on population growth of tobacco aphids reared on upper leaves, for which SAR to TMV was active.
Volatiles from potato plants infected with potato leafroll virus attract and arrest the virus vector, Myzus persicae (Homoptera: Aphididae)
It is shown that previously reported preferential colonization of potatoes infected by potato leafroll virus by alatae of Myzus persicae, the principal aphid vector ofPLRV, is influenced by volatile emissions from PLRV–infected plants.
Plant-mediated interactions between pathogenic microorganisms and herbivorous arthropods.
Research has focused on the role of two plant response pathways in mediating tripartite interactions, one involving jasmonic acid and the other salicylic acid, and will facilitate an understanding of how plants coordinate and integrate their defenses against multiple biotic threats.
Multitrophic effects of herbivore‐induced plant volatiles in an evolutionary context
The induction mechanism as well as the ecological consequences in a multitrophic and evolutionary context, and empirical evidence has been obtained that shows that the plant's response can increase plant fitness, in terms of seed production, due to a reduced consumption rate of parasitized herbivores.
Infection of potato plants with potato leafroll virus changes attraction and feeding behaviour of Myzus persicae
It is found that M. persicae's ability to differentiate headspace volatiles emitted from PLRV‐infected and non-infected potato plants depends on the age of the leaf, which indicates that young leaves seem to be resistant, whereas senescent leaves are susceptible to the virus.
