Western Flower Thrips Can Transmit Tomato spotted wilt virus From Virus-infected Tomato Fruits

Tomato spotted wilt virus

Tomato spotted wilt virus.

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 ...

Biology and Ecology of Flower Thrips in Relation to Tomato Spotted Wilt Virus

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...

Tactics for management of thrips (Thysanoptera: Thripidae) and tomato spotted wilt virus in tomato.

Four studies were conducted in Georgia during spring 1999, 2000, 2001, and 2002 to evaluate various management tactics for reducing thrips and thrips-vectored tomato spotted wilt virus (TSWV) in tomato and their interactions relative to fruit yield. Populations of thrips vectors of TSWV, Frankliniella occidentalis (Pergande) and Frankliniella fusca (Hinds), were determined using flower and stic...

About 300 plant species, mainly broadleafs, are hosts of TSWV. In addition to peanut, other important crops grown in the Southeast that are susceptible to this virus include tomato, pepper, potato, cucurbits, lettuce, eggplant, and tobacco. Chrysanthemum, ...
