Tomato spotted wilt virus, the cause of bud necrosis of peanut, was transmitted by Scirtothrips dorsalis and Frankliniella schultzei. S. dorsalis is a new vector of the virus, but it is a less efficient vector than F. schultzei. Hemagglutination tests detected viral antigens in extracts from both thrips species exposed to infected leaves.
