Abstract		Tospoviruses are important pathogens of ornamental and vegetable crops, such as pepper, peanut, tomato, celery, lettuce, potato, pea, tobacco, onion, chrysanthemum, dahlia, gerbera, iris and many others. They are known to infect more than 800 plant species from 82 plant families. Virus vectors are different insect species from family Thripidae. The most frequent reported vectors are Frankliniella occidentalis, F. schultzei in Thrips tabaci, other recor ed vectors are also F. fusca, T. setosus, T. palmi, Scirtothrips dorsalis and F. intonsa. One vector species is able to effectivelly transmitt only one or few tospovirus species. They feed exclusively on plants and most of them are polyphagous. Tomato spotted wilt tospovirus (TSWV) is one of ten most important plant viruses, causing crop losses worldwide of more than 1 billion US dollars. It is found to infect mostly vegetables and some ornamentals mainly outside greenhouses. Impatiens necrotic spot tospovirus (INSV) is mainly found in greenhouses causing big losses in production of ornamental plants. It does not occur in solanaceous crops. The most effective vector of both viruses is Western flower thrips, Frankliniella occidentalis. TSWV and INSV were detected on some ornamentals, mostly chrysanthemums, in Slovenia in the year 2000. In southwestern part of Slovenia also Iris yellow spot virus (IYSV) infections were found. IYSV was reported only in last years and can cause big crop losses in seed and bulb production of onions. Its most effective vector is reported to be Onion thrips, Thrips tabaci. Methods used for tospovirus identification are based on serological characteristics of nucleoprotein and nucleotide homology of the gene for the same protein. Biology, economical importance and methods for detection and identification of all three tospoviruses will be presented.
