“…Thrips are the primary vectors for Orthotospoviruses , and they also serve as important hosts that provide sites for viral replication ( Rotenberg et al, 2015 ; Gupta et al, 2018 ; Rotenberg and Whitfield, 2018 ). Understanding the interactions between thrips and Orthotospoviruses is a key to controlling the diseases caused by these viruses, which have been the focus of much research ( Zhao and Rosa, 2020 ; Chen et al, 2021 ; Mou et al, 2021 ).…”

“…TZSV can be transmitted by four species of thrips: F. occidentalis , F. schultzei , Thrips palmi and T. tabaci ( Dong et al, 2008 ; Zhao and Wang, 2012 ; Zheng et al, 2014 ; Chen et al, 2021 ). F. occidentalis , the dominant thrips species in several areas of China, is also the main vector of TZSV ( Zheng et al, 2014 ; Yin et al, 2018 ; He et al, 2020 ).…”

Tomato zonate spot virus (TZSV) is a phytopathogen of the genus Orthotospovirus (Bunyaviridae) that is widespread in many areas of Southwest China. TZSV is mainly transmitted by Frankliniella occidentalis, but its exact infection route remains unclear. To explore this issue, we detected the nucleocapsid protein of TZSV in the digestive systems of first-instar F. occidentalis nymphs fed with TZSV-infected pepper leaves. TZSV infection in the F. occidentalis digestive system begins within 4 h post-first access to diseased plants: The foregut is likely the primary site of infection, and primary salivary glands (PSGs) are the destination. There are three potential routes for TZSV transmission from the alimentary canal to the PSGs: (1) virus dissemination from the midgut to hemocoel followed by movement to the PSGs; (2) accumulation in midgut epithelial cells and arrival at PSGs via tubular salivary glands and efferent ducts; and (3) arrival at epitheliomuscular cells of the forepart of the midgut and movement along the ligament to the PSGs. We tested the transmission efficiency of F. occidentalis in second-instar nymphs and female and male adults. TZSV was transmitted in a persistent-propagative mode by both nymphs and adults, with adults appearing to show slightly higher transmission efficiency than nymphs. We confirmed the presence of all three routes for TZSV transmission in F. occidentalis and determined that like other Orthotospoviruses, TZSV is transmitted in a persistent-propagative manner. These results should facilitate the control of TZSV-related diseases and further our understanding of the transmission biology of Orthotospoviruses in general.

“…Wu et al (2020) summarize current knowledge on competitive interactions between WFT and locally present thrips species, and how these interactions affect the invasiveness of WFT. Chen et al (2020) demonstrate that Orthotospovirus infection of a host plant confers a competitive advantage to WFT against Thrips palmi. Qian et al (2020) describe the impacts of elevated CO 2 on a WFT host plant and its succeeding beneficial effects on WFT physiology and life history traits.…”

The Western flower thrips (WFT), Frankliniella occidentalis, is a major threat to a wide range of agricultural crops and rapidly spreads throughout the world. Its international importance as a pest has led to tremendous growth in our knowledge of its biology, ecology, and novel approaches for its management. Unfortunately, the literature on WFT is widely dispersed and many researchers, extension specialists, and IPM practitioners are only now becoming aware of WFT, which has meant that management programs are still reliant on intense insecticide use, especially in recently invaded regions. Due to the current high demand in effective and sustainable control tactics for this pest, Journal of Pest Science dedicates a special issue to WFT. This special issue provides a consolidated review of WFT biology and ecology and helps to highlight alternative and novel management techniques to effectively controlling this pest in the future.

“…B. tabaci MEAM1 and MED species feeding on TYLCCNV-infected tobacco plants increased its egg production and realized fecundity ( Guo et al 2010 ), and the feeding behaviors were promoted in B. tabaci MEAM1 and MED species when feeding on tomato yellow leaf curl virus (TYLCV)-infected plants, for example, the viruliferous B. tabaci spent more time in salivating into sieve elements of plants than did nonviruliferous whiteflies, a behavior essential for viral inoculation of uninfected hosts, indicating that the altered behavior of whiteflies seems likely to increase TYLCV transmission rates ( Liu et al 2013 ). Increasing researches have shown that plant viruses can regulate the growth, mating, immunity, feeding, fecundity, survival, host selection, gene expression, and other characteristics of their insect vectors ( Moreno-Delafuente et al 2013 , Su et al 2015 , Chen et al 2016 , Kaur et al 2017 , Maluta et al 2017 , Safari et al 2019 , Wan et al 2020 , Chen et al 2021 ).…”

Impacts of Cucurbit Chlorotic Yellows Virus (CCYV) on Biological Characteristics of Its Vector Bemisia tabaci (Hemiptera: Aleyrodidae) MED Species

Plant viruses can change the phenotypes and defense pathways of the host plants and the performance of their vectors to facilitate their transmission. Cucurbit chlorotic yellows virus (CCYV) ( Crinivirus ), a newly reported virus occurring on cucurbit plants and many other plant species, is transmitted specifically by Bemisia tabaci MEAM1 (B biotype) and MED (Q biotype) cryptic species in a semipersistent manner. This study evaluated the impacts of CCYV on B. tabaci to better understand the plant-virus-vector interactions. By using CCYV- B. tabaci MED - cucumber as the model, we investigated whether or how a semipersistent plant virus impacts the biology of its whitefly vector. CCYV mRNAs were detectable in nymphs from first to fourth instars and adults of B. tabaci with different titers. Nymph instar durations and adult longevity of female whiteflies greatly extended on CCYV-infected plants, but nymph instar durations and adult longevity of male whiteflies were not significantly influenced. In addition, the body length and oviposition increased in adults feeding on CCYV-infected plants, 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 0.5:1 in whitefly populations on CCYV-infected plants, while the ratio remained about 1:1 on healthy plants. These results indicated that CCYV can significantly impact the biological characteristics of its vector B. tabaci . It is speculated that CCYV and B. tabaci have established a typical mutualist relationship mediated by host plants.
