First report of impatiens necrotic spot tospovirus under glasshouse in UK
In United Kingdom, a survey has been made in commercial protected crops and samples suspected of being infected by tomato spotted wilt or impatiens necrotic spot tospoviruses (both EPPO A2 quarantine pests) were tested. A suspect sample was taken from a Senecio cruentus plant showing necrotic lesions, vein-clearing and stunting. This plant was grown in a nursery in East Sussex (England), where Frankliniella occidentalis (EPPO A2 quarantine pest) also occurred. ELISA and molecular tests (RT-PCR, comparison of nucleotide sequences) confirmed the presence of impatiens necrotic spot tospovirus (INSV) in this sample. This is the first report of INSV in UK.
