“…Thrips hawaiiensis (Morgan) (Thysanoptera: Thripidae), which originates in Oriental and Pacific regions, is one of the most common flower‐dwelling thrips . Mainly as a consequence of the obvious invasive capacity, marked thigmokinetic behavior, high fecundity and short life‐cycle of T. hawaiiensis , more attention is being paid to its introduction and its potential as a major pest of many crops, such as mango, banana, citrus, apple, tea, coffee and tobacco, and many horticultural plants and vegetables . Thrips hawaiiensis damages plants through both oviposition by adults and feeding by larvae on tender leaves, flowers and fruits, inducing spot lesions, scarring and bud malformations or reduced fruit set .…”

“…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.…”

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.

“…This pest species is currently extensively distributed throughout the world (Kirk & Terry, ; Reitz, ). Thrips hawaiiensis (Morgan) is also a highly polyphagous insect found in Asia (Aliakbarpour & Salmah, ; Murai, ), Europe (Atakan, Ölçülü, Pehlivan, & Satar, ; Reynaud, Balmès, & Pizzol, ), and North America (Goldarazena, ). Both species share many ecological niches and biological characteristics, such as a similar body size (1–2 mm), short life history (more than 10 generations per year) and preference for feeding on plant flowers (Cao et al, ; Murai, ).…”

Temperature fluctuations may influence the behaviour of insects. Frankliniella occidentalis and Thrips hawaiiensis are sympatric pests on flower and vegetable host plants in China. This study evaluated the influence of constant (23.0°C) and fluctuating temperatures (average of 23.0°C) on the population development of these two species. The results showed that both of these pests showed faster development and higher fecundity at a constant temperature than at fluctuating temperatures when fed on Rosa rugosa flowers, and F. occidentalis showed faster development and higher fecundity than T. hawaiiensis under both conditions. Under the constant and fluctuating temperatures, the development times from egg to adult were 9.57 and 10.62 day for F. occidentalis and 10.71 and 11.82 day for T. hawaiiensis, respectively. The total numbers of first instar nymph produced were 103.08 and 86.32 by F. occidentalis, 86.96 and 73.32 by T. hawaiiensis, under the constant and fluctuating temperatures, respectively, and a higher intrinsic rate of natural increase (rm) (0.173 and 0.160) and R0 (46.31 and 36.86) were obtained in F. occidentalis compared with T. hawaiiensis (rm for 0.154 and 0.141 and R0 for 34.46 and 27.81, respectively). Our results indicate that the constant temperature had a positive effect on the population development of both F. occidentalis and T. hawaiiensis. Furthermore, F. occidentalis showed a stronger adaptability over T. hawaiiensis at both constant and fluctuating temperatures, according to its faster development and higher fecundity. These results may contribute to the better understanding of the biology of different thrip species, especially the interspecific competition between invasive and native thrips under the changing environment. These findings also provide basic data for the thrip pests control by using fluctuating temperatures.
