“…In addition, increased temperature can impact virus incidence, resulting in an earlier and greater BYDV-PAV titer in wheat [43]. The efficiency of R. padi to transmit BYDV-PAV usually increases as temperature rises inside the optimal thermal thresholds [46,86]. In our research, BYDV-PAV infection altered wheat growth and C:N ratio under the combination of eCO 2 and eT.…”

Climate change impacts crop production, pest and disease pressure, yield stability, and, therefore, food security. In order to understand how climate and atmospheric change factors affect trophic interactions in agriculture, we evaluated the combined effect of elevated carbon dioxide (CO2) and temperature on the interactions among wheat (Triticum aestivum L.), Barley yellow dwarf virus species PAV (BYDV-PAV) and its vector, the bird cherry-oat aphid (Rhopalosiphum padi L.). Plant traits and aphid biological parameters were examined under two climate and atmospheric scenarios, current (ambient CO2 and temperature = 400 ppm and 20 °C), and future predicted (elevated CO2 and temperature = 800 ppm and 22 °C), on non-infected and BYDV-PAV-infected plants. Our results show that combined elevated CO2 and temperature increased plant growth, biomass, and carbon to nitrogen (C:N) ratio, which in turn significantly decreased aphid fecundity and development time. However, virus infection reduced chlorophyll content, biomass, wheat growth and C:N ratio, significantly increased R. padi fecundity and development time. Regardless of virus infection, aphid growth rates remained unchanged under simulated future conditions. Therefore, as R. padi is currently a principal pest in temperate cereal crops worldwide, mainly due to its role as a plant virus vector, it will likely continue to have significant economic importance. Furthermore, an earlier and more distinct virus symptomatology was highlighted under the future predicted scenario, with consequences on virus transmission, disease epidemiology and, thus, wheat yield and quality. These research findings emphasize the complexity of plant–vector–virus interactions expected under future climate and their implications for plant disease and pest incidence in food crops.

“…Despite hardly any response being found to volatiles emitted by mixed-infected plants, it is known that plant viruses can be found either in a single or mixed infection on melons, and this has a direct impact on the plant host and also potentially on their relationships with their insect vector compared to simple infection [50,51]. These double infections often result in more severe visual symptoms than single infections of the same viruses, increasing vector attraction via visual cues [52]. Therefore, studies regarding mixed infections' effects on their vector must be considered in further investigations.…”

“…Recently, Roudine et al [19] found that a total of 11 studies were published regarding the relationship between NE and circulative virus incidence: 5 showed a negative effect, 3 revealed a positive effect, and 2 studies had opposite results, depending on the duration of the trial and the mode of virus transmission [23,52]. They concluded that, in general, the anti-predator behavior of insect vectors, such as higher movement between host plants, does not seem to be a key determinant of the effects of natural enemies on persistently transmitted virus spread [19].…”

Natural enemies are an additional component that may interact directly with the plant–virus–vector association, affecting viral dispersion. In our study, we conducted olfactometry assays to explore how single and mixed infections with CMV or/and CABYV modify the attractiveness of A. colemani to aphid-free and aphid-infested melon plants using two melon genotypes. Subsequently, we investigated the influence of CABYV-infected plants infested by A. gossypii on the parasitism rate and emergence of A. colemani in a dual-choice assay under greenhouse conditions. Our study demonstrates that males showed no preference for either infected or non-infected plants. Female parasitoids exhibit a preference for volatiles emitted by CMV and mixed-infected melon plants over clean air but not over mock-inoculated plants, suggesting a response influenced by plant genotype. Female parasitoid responses to CABYV and its interactions with aphids revealed a preference for mock-inoculated plants over CABYV-infected plants and a parasitism rate slightly higher (7.12%) on non-infected plants. Our study revealed that (1) parasitoids may reject olfactory cues from CABYV-infected plants, potentially interfering with the plant’s “cry for help” response; (2) in the case of CMV, whether in single or mixed infections, non-infected plants are as attractive as infected ones to parasitoids. Our findings suggest that persistent viruses manipulate aphid parasitoid behavior to their advantage, promoting virus disease in melon crops.

“…In addition, increased temperature can impact virus incidence, resulting in an earlier and greater BYDV-PAV titre in wheat (Nancarrow et al, 2014). The efficiency of R. padi to transmit BYDV-PAV usually increases as temperature rises inside the optimal thermal thresholds (Finlay and Luck, 2011;Smyrnioudis et al, 2001b). Under combined eT and eCO2, R. maidis (Fitch) increased its performance and produced higher number of winged aphids, which could increase the spread of plant viruses and exacerbate aphid damage on barley crops (Xie et al, 2014).…”

Hay tantas personas a las que quiero agradecer y que han hecho posible la realización de esta tesis… Gracias Pilar y Elisa, me siento muy afortunada de haberos tenido como directoras de tesis. Pilar, gracias por estar siempre ahí. Para mí eres un gran ejemplo de mujer, no solo por tu excelente labor docente e investigadora, si no por ser tan buena persona, por tu buen hacer y por cuidarnos tanto. Elisa, gracias por apoyarme desde el principio, por animarme a conseguir todos mis retos y por todas tus enseñanzas.Gracias Flor, por tu alegría y por tus enseñanzas en el mundo de las ciencias y los viajes.Es un placer escucharte. Gracias Ángeles, por ser esa paz y humildad que tanto equilibrio y tranquilidad me han dado en numerosas ocasiones. Y gracias Pedro, por enseñarnos cada día un bicho y un libro nuevo (o no tan nuevo) con el que identificarlo. Gracias por despertar nuestro interés y curiosidad por la entomología. Echo mucho de menos sentarme delante de la lupa con tus preguntas inquisidoras, y esa tensión de querer encontrar la pista y la ilusión de, incluso a veces (no muchas), acertar.Gracias Luis, por hacer realidad todas nuestras unidades experimentales, por organizar el laboratorio y tener todo dispuesto cuando lo necesitábamos. Gracias Yara, por tu apoyo y por enseñarme tantas cosas, mi maestra DIY ;-). Gracias Nacho, está claro que esta tesis no hubiera sido posible sin tu ayuda. ¡Te llevas el 10 como contador de pulgones! Gracias por tu predisposición y por venirte conmigo donde hiciera falta. Por los días en el ICA, en el laboratorio, en los invernaderos… por las canciones y los chistes, los malos y los muy malos.Sergio, pozo de sabiduría, me siento muy afortunada de haber compartido estos años contigo. Gracias por haberme ayudado en tantos ensayos, por descubrirme los secretos de las crisopas, y por hacerme darme cuenta de los pequeños detalles. Tu humildad es un ejemplo para mí. Gracias por estar siempre pendiente.Gracias a todos los compañeros con los que he compartido tan buenos momentos en el laboratorio del Amor y que han hecho que sea un placer ir a trabajar. A Agus y a Oscar, con los que disfruté la última etapa "acompañada" de la tesis. Por las rancheras, los bailes y vuestra filosofía de vida. Gracias a las Chicas del Altillo por ser tan maravillosas.Andrea, por tu alegría contagiosa y felicidad constante. Ana Murcia, por tu tranquilidad y sosiego, que a veces tanto necesitaba, por ser tan buena compañera. Míriam, aunque fueron poquitos meses, me encantó volver a tenerte como compañera. Celeste, gracias por ¡TODO! Tengo una suerte infinita de haber podido hacer el doctorado con el apoyo incondicional y acompañada en todo momento de mi gran amiga. Ha sido estupendo compartir cada día de esta etapa contigo y, aparte de trabajar, reír, llorar, aprender, soñar, sobre todo, disfrutar de la vida juntas.
