“…Portulaca oleracea was shown to be susceptible to TSWV but supported low feeding and reproduction by thrips. Atakan et al () found a high incidence of TSWV infection in P. oleracea in the field in Turkey, but reported that this species did not favour reproduction of F. occidentalis . However, this species and Son.…”

“…Several studies on the importance of weeds as reservoirs of TSWV and as hosts of different thrips species have been performed in temperate production systems in Europe, North and South America, Asia and Australia (Wilson, ; Gracia et al , ; Groves et al , ; Chatzivassiliou et al , ; Okazaki et al , ; Atakan et al , ). Few similar studies have been carried out in tropical areas.…”

Tomato spotted wilt virus (TSWV) is an important plant virus that infects a wide range of hosts including weeds making its management difficult. A survey was undertaken to establish the occurrence of weed species in tomato production systems in Kenya and their role as hosts of TSWV and its vectors. Selected weed species were further evaluated for their reaction to TSWV, transmission efficiency by Frankliniella occidentalis and ability to support thrips reproduction. Of the 43 weed species identified in the field, 29 species had been reported as hosts of TSWV, two were non-hosts and 11 had no record of their status. Among the more common species, Amaranthus hybridus, Solanum nigrum, Tagetes minuta and Datura stramonium were susceptible to the virus and supported high levels of thrips reproduction. The TSWV could not be transmitted to Galinsoga parviflora and Sonchus oleraceus by F. occidentalis despite them being highly susceptible in mechanical transmission tests. There was a significant correlation between feeding damage and number of larvae of F. occidentalis on different weeds. Occurrence of weeds that support thrips reproduction and are good hosts of TSWV is a clear indicator of their role in epidemiology and the importance of their management for disease control.

“…However, irrespective of location and year, most weeds did not show symptoms of TSWV infection nor high rates of infection, i.e.,~2% of total weeds were infected (Table 1). This is in contrast to many other parts of the world, where certain weeds can have high rates of TSWV infection and serve as important inoculum sources [11,13,16,52,56,[82][83][84][85][86][87][88][89][90][91][92][93][94][95][96][97][98][99][100][101]. Furthermore, the finding that many of the weeds that tested positive for TSWV were collected during the tomato growing season and from in or around fields of tomato or other crops with TSWV-infected plants indicates that many of these weeds were infected during the growing season, with infected tomato or crop plants likely serving as the source of inoculum.…”

“…Consistent with this observation, the first TSWV outbreak in processing tomatoes in the northern counties in 2013 and 2014 occurred in fields that were adjacent to walnut orchards that had TSWV-infected buttercup plants. Buttercup weeds have been previously reported to be infected with TSWV, e.g., Ranunculus sardous (hairy buttercup) in southeastern USA [102][103][104] and R. muricatus in Turkey, where it has been proposed to be a potential source of inoculum for TSWV for crop plants [83,105]. However, this is the first report of R. muricatus infected by TSWV in the USA.…”

Development of an IPM Strategy for Thrips and Tomato spotted wilt virus in Processing Tomatoes in the Central Valley of California

Tomato spotted wilt virus (TSWV; species Tomato spotted wilt orthotospovirus; genus Orthotospovirus; family Tospoviridae) is a thrips-transmitted virus that can cause substantial economic losses to many crops, including tomato (Solanum lycopersicum). Since 2005, TSWV emerged as an economically important virus of processing tomatoes in the Central Valley of California, in part due to increased populations of the primary thrips vector, western flower thrips (WFT; Frankliniella occidentalis). To develop an understanding of the epidemiology of TSWV in this region, population densities of WFT and incidence of TSWV were monitored in California’s processing tomato transplant-producing greenhouses and associated open fields from 2007 to 2013. Thrips were monitored with yellow sticky cards and in tomato flowers, whereas TSWV incidence was assessed with indicator plants and field surveys for virus symptoms. All thrips identified from processing tomato fields were WFT, and females were three-fold more abundant on sticky cards than males. Symptoms of TSWV infection were observed in all monitored processing tomato fields. Incidences of TSWV ranged from 1 to 20%, with highest incidence found in late-planted fields. There was no single primary inoculum source, and inoculum sources for thrips/TSWV varied depending on the production region. These results allowed us to develop a model for TSWV infection of processing tomatoes in the Central Valley of California. The model predicts that low levels of primary TSWV inoculum are amplified in early-planted tomatoes and other susceptible crops leading to highest levels of infection in later-planted fields, especially those with high thrips populations. Based upon these findings, an integrated pest management (IPM) strategy for TSWV in processing tomatoes in California was devised. This IPM strategy focuses on strategic field placement (identification of high-risk situations), planting TSWV- and thrips-free transplants, planting resistant varieties, monitoring for TSWV symptoms and thrips, roguing infected plants, thrips management targeting early generations, extensive sanitation after harvest, and strategic cropping to avoid overlap with winter bridge crops.

“…However, F. occidentalis was more prevalent in plum and nectarine flowers in Yenice, which may be attributed to the production of fruit trees and other alternative host plants like winter and summer vegetables in the area. It has been pointed out that F. occidentalis was a common species on vegetables both in the open field and greenhouses and has an important role in the transmission of TSWV disease, particularly in peppers around the region (Atakan et al, 2013).…”

The distribution, abundance and damage status of Thysanoptera species were investigated in two different regions of Mersin Province, Türkiye between 2020 and 2021. A total of 18 Thysanoptera species were determined, with Thrips major Uzel, 1895 and Frankliniella occidentalis (Pergande, 1895) (Thysanoptera: Thripidae) being the most common. While nectarine had the highest diversity of habitats for thrips, plum displayed greater richness in terms of species composition. Adult thrips primarily inhabited flowers while T. major larvae were present during petal fall periods. No larvae of F. occidentalis or Thrips tabaci Lindeman,1889 (Thysanoptera: Thripidae) were found on the plant parts sampled throughout the samplings. Although no visible signs of damage by adult thrips were observed on the flowers, typical damage in the form of silvery scars appeared on the young fruits of nectarines and plums. The average rate of scarred fruit of nectarines or plums varied between 2-7%. Finally, T. major was the main pest thrips species responsible for damaging fruits of the plums and nectarines in Mersin.
