Thrips Population

Frankliniella occidentalis  (Pergande) (Thysanoptera: Thripidae) is an important pest in vegetable and ornamental greenhouse crops due their direct damage by feeding and indirect damage by vectoring Tomato Spotted Wilt Virus (TSWV). Also, is very well known that they have an extremely high resistance to a wide range of insecticide. Thus by monitoring thrips population appropriate control plans can be established. Western flower thrips was reported in all greenhouses from Cluj County (Romania). In order to assess thrips population dynamic and color preference we conducted a research in a plastic greenhouse of 8000 m 2 placed outside of Cluj-Napoca where the main cultivated crops were tomatoes ( Solanum lycopersicum ) and the main thrips pest found was western flower thirps. During the sample period pest population was monitored weekly using two methods: by counting thrips trapped on five different colored sticky cards (blue, yellow, white, red and transparent) and by a technique based on leaves tapping. Data analysis showed no correlation between traps and tapping method. Blue and yellow traps had the highest attractiveness compared with all the others colors and between those, blue proved to be the most effective.

AbstractA wide range in feeding damage as defined by leaf scars among 27 cultivars of florist’s chrysanthemum was apparent for the western flower thrips, Frankliniella occidentalis (Pergande). Assessments based on numbers of feeding scars or ranking of cultivars on the basis of the leaf area damaged by feeding were in close agreement. Cultivars with the most feeding damage under growth room conditions, such as cvs. White Marble and Polaris, were the same as those in plots within a naturally infested commercial greenhouse. Under growth room conditions, a 2- to 4-week exposure of plants to a population of thrips was sufficient to evaluate feeding damage. Closely related cultivars had similar levels of feeding damage, and foliage of yellow-flowered cultivars was significantly more attractive to thrips for feeding than foliage of white-flowered sister cultivars during the pre-bloom period. There was a low correlation between feeding damage and incidence of the tomato spotted wilt virus among cultivars in both growth room and greenhouse tests, indicating that virus susceptibility of cultivars was epidemiologically more significant than the feeding activity of western flower thrips.

Wilt Virus

The western flower thrips, Frankliniella occidentalis (Pergande), occurs from sea level to subalpine altitudes in western North America (Bryan and Smith 1956). Until recently, it was assumed that this species was found primarily west of the Rocky Mountains and that Frankliniella tritici (Fitch), the eastern flower thrips, was the dominant flower thrips in both eastern Canada and United States. Beshear (1983) reported F. occidentalis on cotton, peas, beans, and peanuts in Georgia. The following year, in the Niagara Peninsula of Ontario, the tomato spotted wilt virus caused extensive crop losses to greenhousegrown tomatoes and ornamentals. The virus-vector was identified as F. occidentalis (Allen and Broadbent 1986). Previously, F. fusca was the only known vector of tomato spotted wilt virus in Ontario and the eastern provinces (Paliwal 1974, 1976).

The Impact

The impact of tospovirus infection on the behaviour of western flower thrips (Frankliniella occidentalis) was evaluated in a Ytube olfactometer The response of female western flower thrips with or without a tospovirus (Tomato spotted wilt virus TSWV) to a thrips lure (methyl isonicotinate MI) and chrysanthemum buds was recorded Compared to the blank arm significantly more thrips chose the odourladen arm of the Ytube when it contained MI (65 P016) increase the percentage of thrips that chose the odourladen arm over and above the cleanair arm but thrips (virusfree and infected) moved more quickly to the end of either arm when a bud was present The virus status of thrips was confirmed with RTPCR The presence of the virus in the vector did not substantially affect the behavioural response of the vector to a lure or hostplant material (P>04)

Wilt Virus

In this study, we demonstrate that western flower thrips (WFT, Frankliniella occidentalis) can acquire and transmit Tomato spotted wilt virus (TSWV) from symptomatic tomato fruits. TSWV and other thrips-transmitted tospoviruses have long been known to spread via plant propagation material such as transplants. Global dissemination of tospoviruses has also been linked, in part, to transport and trade of thrips-infested and virus-infected horticultural products. However, the role of tomato fruits transported across state and national borders has not previously been examined as a means of virus spread or as a source for thrips acquisition of virus. Tomato fruits displaying typical tospovirus symptoms were purchased from several Washington State grocery stores. Many of these symptomatic fruits tested positive for TSWV and some for Pepino mosaic virus (PepMV). First instar larvae of WFT successfully acquired TSWV from these infected tomato fruits and transmitted the virus as adults to Emilia sonchifolia plants. Symptomatic E. sonchifolia plants were confirmed positive for TSWV by lateral flow immunoassays and sequence analysis of a portion of the nucleocapsid gene. These results suggest the dissemination of TSWV (and likely other tospoviruses) and PepMV to new geographic areas by human-assisted transport of infected tomato fruits.
