“…For example, Dáder and colleagues [8] found that an induced dispersal of A. gossypii carrying CMV or CABYV transmitted in non-circulative and circulative manner, respectively, led to an increase in CMV spread in the short term, while the spread of CABYV was significantly limited. A similar finding was reported by Lin and colleagues [12] with M. persicae and M. euphorbiae, both transmitting PVY and PLRV in non-circulative and circulative manners, respectively. Here, there was a trend of decreased PLRV spread, without being significantly different from the control where there was no stimulation of insect dispersal.…”

“…Spring migrants transmit phytoviruses acquired from alternate hosts in early spring to crop plants while summer migrants transmit phytoviruses within the field from one plot to another, more or less distant, during plant-to-plant movements over several generations [11]. As for wingless, they spread the infection by walking from one plant to another in the vicinity of the initially colonised plant [12]. Finally, fall migrants are involved in the transmission of new phytoviruses which were acquired in the field from distant sources to the alternate hosts (reservoir plants) [11].…”

Aphids are responsible for the spread of more than half of the known phytovirus species. Virus transmission within the plant–aphid–phytovirus pathosystem depends on vector mobility which allows the aphid to reach its host plant and on vector efficiency in terms of ability to transmit phytoviruses. However, several other factors can influence the phytoviruses transmission process and have significant epidemiological consequences. In this review, we aimed to analyse the aphid behaviours and influencing factors affecting phytovirus spread. We discussed the impact of vector host-seeking and dispersal behaviours mostly involved in aphid-born phytovirus spread but also the effect of feeding behaviours and life history traits involved in plant–aphid–phytovirus relationships on vector performances. We also noted that these behaviours are influenced by factors inherent to the interactions between pathosystem components (mode of transmission of phytoviruses, vector efficiency, plant resistance, …) and several biological, biochemical, chemical or physical factors related to the environment of these pathosystem components, most of them being manipulated as means to control vector-borne diseases in the crop fields.

“…Some biocontrol agents (such as macroorganisms) and semiochemicals (such as alarm pheromones) that are used to control aphids enhance the spread of viruses [ 42 , 43 , 44 ]. Thus, it is important to understand the relationship between an EEPF-inoculated plant and an aphid when carrying and not carrying viruses.…”

Aphids (Hemiptera: Aphididae) cause significant damage and transmit viruses to various crop plants. We aimed to evaluate how the infectious status of aphids influences their interaction with potential hosts. Two aphid (Myzus persicae and Rhopalosiphum padi) and plant (Nicotiana tabacum and Triticum aestivum) species were used. The preferences of aphids towards healthy, virus-infected (Potato Leafroll Virus (PLRV) and Barley Yellow Dwarf virus (BYDV)), and endophytic entomopathogenic fungi (EEPF)-inoculated (Beauveria bassiana and Metarhizium acridum) plants were investigated in dual-choice tests. The headspace volatiles of the different plant modalities were also sampled and analyzed. Viruliferous and non-viruliferous aphids were more attracted to EEPF-inoculated plants compared to uninoculated plants. However, viruliferous aphids were more attracted to EEPF-inoculated plants compared to virus-infected plants, while non-viruliferous insects exhibited no preference. Fungal-inoculated plants released higher amounts of aldehydes (i.e., heptanal, octanal, nonanal and decanal) compared to other plants, which might explain why viruliferous and non-viruliferous aphids were more abundant in EEPF-inoculated plants. Our study provides an interesting research perspective on how EEPF are involved in behavior of virus vector, depending on the infectious status of the latter.

“…However, plant quality might be sufficiently altered by rising CO 2 concentrations to affect the feeding behavior of aphids, but not their spread. As demonstrated by Lin et al (2016), the higher the dispersal rate of aphids, the greater the transmission of viruses in plots. Furthermore, Fu et al (2010) have shown a significantly higher abundance of M. persicae when reared on tobacco under eCO 2 concentration, from the 12th day of their experiment.…”

Most phytoviruses use insect vectors to spread and infect the surrounding crop plants. Because atmospheric gas concentrations alter the physiology and metabolism of plants, we hypothesize that the concentration of carbon dioxide (CO 2 ) affects the spread of viruses, due to modifications in the feeding behavior of the vector. Tobacco plants, Nicotiana tabacum L. (Solanaceae), and green peach aphids, Myzus persicae (Sulzer) (Hemiptera: Aphididae), were cultivated under ambient (450 p.p.m., termed aCO 2 ) and elevated (800 p.p.m., eCO 2 ) concentrations of CO 2 . For each atmospheric condition, we first evaluated the ability of the Potato virus Y to spread in a small experimental design, from a central infected tobacco plant to two surrounding circles of healthy plants in presence of aphid vectors for 7 days. The number of aphids recovered on each plant and the infection status of the plants (i.e., healthy vs. infected) were assessed at the end of the experiment. We also evaluated the ability of aphids to transmit the virus under the two experimental atmospheres, by immediately transferring a single insect from an infected plant to a healthy one. The presence of virus in healthy plants was then determined. We found that aphid dispersal, as well as the associated spread of viruses, did not differ between the two atmospheres. On the other hand, we found that aphids grown under eCO 2 were more efficient in transmitting viruses to healthy plants compared to aphids reared under aCO 2 conditions. The results of this experiment indicate that: (1) the ability of an aphid vector to spread a phytovirus is not affected by the level of CO 2 at short time and spatial scales, but (2) the concentration of CO 2 may affect plant defenses or the feeding behavior of herbivorous insects, resulting in more efficient viral transmission from the vector to the host plant.
