摘要：Tropical soda apple (TSA), Solanum viarum Dunal (Solanaceae), a perennial prickly weed native to South
America (Fig. 1), has been spreading rapidly in the USA since it was discovered in Glades County, Florida in 1988. In Florida,
approximately 150,000 acres (60,704 ha) of pasture land were infested in 1992 (Mullahey et al. 1993). Currently, the infested area is
estimated at over 1 million acres (404,694 ha). TSA also invades hammocks, ditch banks, citrus groves, vegetable fields, sugarcane
fields and roadsides. TSA also has been reported in Alabama, Georgia, Louisiana, Texas, Mississippi, North Carolina, South Carolina,
Tennessee, Pennsylvania and Puerto Rico (Bryson and Byrd Jr. 1996; Dowler 1996; Mullahey et al. 1997; Phil Lewis personal communication).
TSA was placed on the Florida Noxious Weed List in 1994, and the Federal Noxious Weed List in 1995, and is listed as one
of the most invasive species in Florida by the Florida Exotic Pest Plant Council (1999) (Fig. 2).
