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 …

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 …

INNOVATIVE APPROACHES TO PLANT PROTECTION AND PRODUCE SAFETY THROUGH HIGH-PRECISION PLANT MANAGEMENT SYSTEMS
… relevant crops such as lettuce, cucumber, tomato, bell pepper, and wild rocket, assessing their effectiveness against fungal and viral pathogens, as well as their impact on plant physiology and microbial community dynamics. In the first study, six bacterial strains were evaluated as BCAs …
