Transmission of chrysanthemum stem necrosis virus, a recently discovered Tospovirus, by two thrips species
Journal of Phytopathology - Phytopathologische Zeitschrift 148 (2), 123-125
Abstract: The biological transmission of a recently discovered tospovirus species, Chrysanthemum stem necrosis virus (CSNV), was studied. The transmission capacity of three thrips species (Frankliniella schultzei, Frankliniella occidentalis and Thrips tabaci) was tested using a leaf disc assay combined with DAS-ELISA. This capacity was tested with adults which were given an acquisition access period of 16 h on CSNV-infected plants as new-born larvae, up to 8 h old. The virus was efficiently transmitted by F. schultzei (78.1%) and F. occidentalis (65.1%), but not at all by T. tabaci (0.0%). Infection was confirmed in adult thrips; high virus titres were found in 75.9% of F. schultzei and 97.4% of F. occidentalis adults. Although T. tabaci did not transmit CSNV in this study, comparatively low amounts of virus were detected in 75.0% of the tested population. The results obtained showed that F. occidentalis and F. schultzei may be the major vectors of CSNV in Brazil.
