Inheritance of Resistance to Tomato Spotted Wilt Virus in Lettuce (Lactuca Sativa L.)
Tomato Spotted Wilt Virus (TSWV), a thrips transmitted virus disease with a wide host range, has become a major limiting factor in lettuce production in Hawaii. Symptoms of this disease on lettuce are necrotic spotting of young leaves, stunting, wilting, and death of the plant. The large host range …

Characterizing global gene expression and antiviral response in Frankliniella occidentalis infected with Tomato spotted wilt virus
… flower thrips, transmits the plant-pathogenic virus, Tomato spotted wilt virus (TSWV), through a circulative-propagative transmission strategy. The virus infects and replicates in the insect, traversing membrane barriers as it moves from the midgut to the salivary glands for subsequent …

The effectiveness of biological control of Frankliniella occidentalis in prevention of the spread of Tomato spotted wilt virus
… as a means of reducing the spread of Tomato spotted wilt virus (TSWV) on tomatoes. To compare efficacy of different thrips management tactics for reducing TSWV incidence, tomatoes were subjected to one of three treatments: 1) biological control based on weekly releases of the predatory …

The Role of Temperature and Precipitation on Thrips Populations in Relation to the Epidemiology of Tomato Spotted Wilt Virus.
… Populations in Relation to the Epidemiology of Tomato Spotted Wilt Virus. (Under the direction of George G. Kennedy.) The influence of temperature and precipitation on spread of Tomato spotted wilt virus (family Bunyaviridae, genus Tospovirus, TSWV) in chickweed (Stellaria media), population …

Investigation of In Season Progression of Tomato spotted wilt virus and its Management in Flue-cured Tobacco Fields of North Carolina
Tomato spotted wilt virus continues to be a serious problem on tobacco production in the southeast United States. The current control recommendation calls for acibenzolar-S-methyl, which is known by growers in North Carolina to have unacceptable phytotoxicity. In an attempt to reduce the amount of …

Incidence, Distribution and Characteristics of Major Tomato Leaf Curl and Mosaic Virus Diseases in Uganda
In Uganda, about 3 million households consume tomato. However, tomato yields (10 ton/ ha) are low due to poor agronomic practices, lack of high yielding and disease resistant varieties, and pests (Varela, 1995; Hansen, 1990; Defrancq, 1989). Viral diseases are the third major cause of low tomato …

Efficient Prevalence Estimation for Emerging and Seasonal Diseases Under Limited Resources
… estimation of the human immunodeficiency virus (HIV) in various parts of Africa, to prevalence estimation of diseases in plants and insects, including the Tomato Spotted Wilt virus in thrips and West Nile virus in mosquitoes, indicate that the proposed estimation methods substantially …

Movement patterns and phenology of the tobacco thrips, Frankliniella fusca (Hinds), in Virginia peanuts
… role of tobacco thrips in the epidemiology of tomato spotted wilt virus in peanuts; the short-term goal was to develop quantitative descriptions of thrips development and movement for inclusion in a systems model intra-field movement patterns were assessed by establishing an isolated population …

Studies on Transformation of Tomato(Solanum lycopersicum L.) and Arabidopsis thaliana using Chimerical constructs of varying Tospoviral Origin
… viral genes. Given the severity of Tospovirus diseases worldwide (particularly in tomato), PDR has the potential to garner large yield returns where pathogen populations have overcome the established resistance. Tomato breeding lines FLA7804, FLA8044, and the research line MP1 were used …

Enhancement of plant expression vectors using replication and silencing suppressor elements
… for difficult to express proteins. In this study virus-derived silencing suppressors and replication elements were used with the aim of increasing expression and yield of enhanced green fluorescent protein (EGFP) and the Zika PrME polyprotein in Nicotiana benthamiana. A comparison of four viral …

Monitoring and management of thrips populations in vegetables, row crops, and greenhouse crops in Virginia
… occidentalis can transmit plant pathogenic tospoviruses, such as tomato spotted wilt virus (TSWV), in certain susceptible crops. While all of these thrips species are difficult to detect due to their cryptic lifestyles, F. occidentalis is a particularly challenging pest to manage due to its …

Influence of Tillage and Cropping System on Soil Quality and Crop Yield in North Carolina
… for peanut and soybean and a detriment to corn. Tomato spotted wilt virus (a Tospovirus) (TSWV) and Cylindrocladium black rot (Cylindrocladium parasiticum Crous, Wingfield, and Alfenas) (CBR) are important pests in peanut in North Carolina. Implementing integrated pest management (IPM) strategies …
