abstract tomato spotted wilt virus (tswv) was detected in tomato leaf and fruit samples collected from viiramin reyion in tehran province using indicator test plants including petunia hybrida, nicatiana glutinosa, n. tabacum cv. snmsun nn, n. clevelandit and n. benthamiana and seroloyical tests. small browinsh local necrotic lesions appeared on p. hybrida leaves 2-4 days post-inoculation. syste...

Frankliniella occidentalis is the key vector responsible for the emergence of Tomato spotted wilt virus as a global threat to agriculture. Frankliniella bispinosa is a common thrips in Florida, the Bahamas, and Bermuda, but the role of F. bispinosa in the epidemiology of the virus is not known. The purpose of this study was to determine the ability of F. bispinosa to acquire and transmit Tomato...

Tomato spotted wilt caused by thrips-vectored tomato spotted wilt virus (TSWV) is a very serious problem in peanut (Arachis hypogaea L.) production. TSWV and the thrips Frankliniella fusca and Frankliniella occidentalis, which vector the virus, present a difficult and complicated challenge from the perspectives of both epidemiology and disease management. Simply controlling the vector typically...

Growers in Georgia first noted problems in their peppers and onions during the last week of March 1989. Thrips populations combined with further field symptoms and the verification of the disease triggered a massive insecticide spray program in Georgia. Monitor was first used in early May followed by combinations of Orthene, Cygon and Thiodan. Most fields had less than 1% infection prompting a ...

Orchid plants are the members of Orchidaceae consisting of more than 25,000 species, which are distributed almost all over the world but more abundantly in the tropics. There are 177 genera, 1,125 species of orchids that originated in Thailand. Orchid plant collected from different nurseries showing Chlorotic and mosaic symptoms were observed on Vanda plants and it was suspected to infect with ...

ABSTRACT Different levels of thrips resistance were found in seven Capsicum accessions. Based on the level of feeding damage, host preference, and host suitability for reproduction, a thrips susceptible and a resistant accession were selected to study their performance as Tomato spotted wilt virus (TSWV) sources and targets during thrips-mediated virus transmission. Vector resistance did not af...

Tomato Spotted Wilt Virus (TSWV) is transmitted exclusively by certain species of thrips. Because TSWV can only be acquired by larvae and transmitted by adults, it is essential to determine the ecology of these different life stages to improve management of thrips and TSWV. Furthermore, interspecific differences among vector species complicate management issues. Herein, aspects of the biology a...

Through a modeling approach, we investigated weather factors that affect the summer incidence of Tomato spotted wilt virus (TSWV), a virus vectored exclusively by thrips, in cultivated tobacco. Aspects of thrips and plant biology that affect disease spread were treated as functions of weather, leading to a model of disease incidence informed by thrips and plant biology, and dependent on weather...
