“…Plant viruses can manipulate vector insects by directly in uencing the feeding behavior. For example, B. tabaci carrying CCYV increased non-phloem probing and phloem salivation [24]. B. tabaci with TYLCV spend more time in phloem salivating and ingesting sap [28].…”

“…CCYV seriously affected the yield and quality of melons in most parts of China and many Asian countries [21]. In our previous study, we found that CCYV had direct and indirect effects on the feeding behavior of B. tabaci, and the degree of in uence depends on the biological type (cryptic species) and sex of the insects [23,24]. However, there have been no reports about the effect of CCYV on the biological characteristics of B. tabaci.…”

It is known that plant viruses, to facilitate their transmission, can change the phenotypes and defense pathways of the host plants and the performance of their vectors. Cucurbit chlorotic yellows virus (CCYV), a newly reported virus occurring on cucurbit plants and many other plant species, is transmitted specifically by Middle East-Minor Asia 1 (B biotype) and Mediterranean (Q biotype) cryptic species of whitefly, Bemisia tabaci (Gennadius), in a semipersistent manner. This study evaluated the direct and indirect effects of CCYV on B. tabaci biology to better understand the plant-virus-vector interaction. By using CCYV-B. tabaci-cucumber as the model, we investigated whether or how a semipersistent plant virus impacts the biology of its whitefly vectors. CCYV mRNA were detectable in nymphs from 1st to 4th instars and adults of B. tabaci with different titers. Female nymph duration and female adult longevity greatly extended on CCYV-infected plants, but male nymph duration and male adult longevity were not significantly influenced. In addition, on CCYV-infected plants, the body length and oviposition of adult B. tabaci increased, but the hatching rates of eggs and survival rates of different stages were not affected. Most interestingly, the sex ratio (male:female) significantly reduced to 0.506:1 in whitefly populations on CCYV-infected plants, while the ratio remained about 0.979:1 on healthy plants. These results indicated that CCYV can significantly impact the biological characteristics of its vector B. tabaci through the host plants. It is speculated that CCYV and B. tabaci have established a typical mutualist relationship mediated by host plants.

“…The crinivirus cucurbit chlorotic yellows virus is transmitted by B. tabaci in a semi-persistent manner. Acquisition of the virus changed feeding behaviour in a biotype and sex dependent manner, but, overall, the results suggested an increased ability of the vector to transmit the virus [ 177 ]. Vector feeding behaviour can be modified to enhance the probability of transmission, as has been shown for some plant viruses belonging to the Bunyaviridae [ 117 , 118 ], a trait shared with animal infecting members of this virus family.…”

The Epidemiology of Plant Virus Disease: Towards a New Synthesis

Epidemiology is the science of how disease develops in populations, with applications in human, animal and plant diseases. For plant diseases, epidemiology has developed as a quantitative science with the aims of describing, understanding and predicting epidemics, and intervening to mitigate their consequences in plant populations. Although the central focus of epidemiology is at the population level, it is often necessary to recognise the system hierarchies present by scaling down to the individual plant/cellular level and scaling up to the community/landscape level. This is particularly important for diseases caused by plant viruses, which in most cases are transmitted by arthropod vectors. This leads to range of virus-plant, virus-vector and vector-plant interactions giving a distinctive character to plant virus epidemiology (whilst recognising that some fungal, oomycete and bacterial pathogens are also vector-borne). These interactions have epidemiological, ecological and evolutionary consequences with implications for agronomic practices, pest and disease management, host resistance deployment, and the health of wild plant communities. Over the last two decades, there have been attempts to bring together these differing standpoints into a new synthesis, although this is more apparent for evolutionary and ecological approaches, perhaps reflecting the greater emphasis on shorter often annual time scales in epidemiological studies. It is argued here that incorporating an epidemiological perspective, specifically quantitative, into this developing synthesis will lead to new directions in plant virus research and disease management. This synthesis can serve to further consolidate and transform epidemiology as a key element in plant virus research.

“…Similarly, plant viruses also directly influence vector feeding behavior to facilitate their transmission ( Mauck et al, 2018 ). Several reports show that infection of insect vectors with tomato spotted wilt virus (TSWV), tomato yellow leaf curl virus, rice dwarf virus, and southern rice black-streaked dwarf virus (SRBSDV) is associated with increased insect feeding frequency and prolongs salivation period ( Maris et al, 2004 ; Xu et al, 2014 ; Lei et al, 2016 ; Tan et al, 2017 ; Wang et al, 2018 ; Lu et al, 2019 ). Moreover, vector feeding behavior is correlated with sex and vector biotypes.…”

Delivery of Rice Gall Dwarf Virus Into Plant Phloem by Its Leafhopper Vectors Activates Callose Deposition to Enhance Viral Transmission

Rice gall dwarf virus (RGDV) and its leafhopper vector Recilia dorsalis are plant phloem-inhabiting pests. Currently, how the delivery of plant viruses into plant phloem via piercing-sucking insects modulates callose deposition to promote viral transmission remains poorly understood. Here, we initially demonstrated that nonviruliferous R. dorsalis preferred feeding on RGDV-infected rice plants than viruliferous counterpart. Electrical penetration graph assay showed that viruliferous R. dorsalis encountered stronger physical barriers than nonviruliferous insects during feeding, finally prolonging salivary secretion and ingestion probing. Viruliferous R. dorsalis feeding induced more defense-associated callose deposition on sieve plates of rice phloem. Furthermore, RGDV infection significantly increased the cytosolic Ca2+ level in rice plants, triggering substantial callose deposition. Such a virus-mediated insect feeding behavior change potentially impedes insects from continuously ingesting phloem sap and promotes the secretion of more infectious virions from the salivary glands into rice phloem. This is the first study demonstrating that the delivery of a phloem-limited virus by piercing-sucking insects into the plant phloem activates the defense-associated callose deposition to enhance viral transmission.
