The symptoms of this emerging virus were first recognized in 2003-2004 in Wielkopolska, a region of Poland and included leaf necrosis, severe stunting and malformation (apparently usual symptoms for a tomato virus). There was an association drawn between such affliction and greenhouse whiteflies (Trialeurodes vaporariorum).
In a recently published article, The first report of Tomato torrado
virus in Poland, by H. Pospieszny et al, the virus was identified and shown to be similar to the tomator necrotic dwarf virus (ToNDV) (California) and the newly identified tomato torrado virus (ToTV) (Spain). The association with the whitefly was also demonstrated as these flies were shown to vector the virus.
