Replication of tomato spotted wilt tospovirus in cells of Frankliniella occidentalis
At the 1992 Annual Meeting of the American Phytopathological Society a report was presented which gave evidence of the replication of tospoviruses in cells of Frankliniella occidentalis (EPPO A2 pest). Immunocytochemical analyses for tomato spotted wilt tospovirus (potential EPPO A2 pest) encoded proteins in thrips were carried out and showed that an encoded non-structural protein of TSWV, an indicator of replication, is present in cells of thrips fed on TSWV-infected plants. In cells of larval thrips fed on plants infected with tomato spotted wilt tospovirus virions, viroplasm, dense masses and inclusions of fibrous paracrystalline material were observed with transmission electron microscopy.
