Tentative geographical distribution list for impatiens necrotic spot tospovirus
As impatiens necrotic spot tospovirus (EPPO A2 quarantine pest) has only recently been distinguished from tomato spotted wilt tospovirus (Avila et al., 1992), its geographical distribution remains to be further studied. The EPPO Secretariat has tried to collect recent geographical records which specifically concern impatiens necrotic spot tospovirus and appear reasonably confirmed, but it is likely that this virus is more widespread. A Distribution Map has recently been published by CABI in association with EPPO, and all references for these records can be found there, unless specified otherwise.
EPPO Distribution List: Impatiens necrotic spot tospovirus
EPPO region: Belgium (VIDE database), France (EPPO RS 93/089), Germany (VIDE database), Italy (EPPO RS 97/136, in several regions: Emilia-Romagna, Liguria (Vaira et al., 1992), Piemonte, Puglia, Sicily, Toscana (Vicchi ; Bellardi, 1996)), Netherlands, Poland (found in 1994/95, see EPPO RS 97/170), Portugal (found on imported material), Spain, UK (see EPPO RS 99/022).
North America: Canada (British Columbia (reported in 1996 as a new minor disease on Kalanchoe and Stephanotis, INTERNET), Manitoba (reported as TSWV-I)), Mexico, USA (Arkansas, California, Colorado (INTERNET), Connecticut, Delaware, Florida, Georgia, Idaho (Hall et al., 1993), Iowa, Kansas, Kentucky, Maine, Maryland, Massachusetts, Mississippi, Missouri, New Hampshire, New Jersey, New York, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, South Carolina, Texas, Vermont, Virginia). All these state records for USA came from EPPO RS 98/181 or CABI map, unless specified otherwise.
