P-IE: Vectors of Plant Pathogens

Development of a management program to control thrips (Thysanoptera: Thripidae) and their transmitted tomato chlorotic spot virus in South Florida tomatoes

Tomato chlorotic spot virus (TCSV) is an important viral disease of tomatoes. Common blossom thrips (Frankliniella schultzei), western flower thrips (F. occidentalis) are the known vectors of TCSV.  Melon thrips (Thrips palmi) role in transmitting TCSV is not clear.  These three thrips species are common in all tomato fields, with the melon thrips as the most abundant one.  In developing a management program, we addressed various chemical insecticides, placement of reflective plastic mulch, biocontrol agents and various tomato cultivars.  All these techniques together provided suppression of TCSV and vector thrips.
