The detection, distribution, molecular and biological properties, vector relations and control of tospoviruses present in Australia, including Tomato spotted wilt virus (TSWV), Capsicum chlorosis virus (CaCV) and Iris yellow spot virus (IYSV), are reviewed. TSWV occurs throughout Australia where it has caused serious sporadic epidemics since it was first described in the 1920s. The frequency and distribution of outbreaks has increased in the 1990s, with the arrival and dispersal of the western flower thrips (Frankliniella occidentalis) being one factor favouring this situation. The crops most frequently and severely affected are capsicum, lettuce, tomato, potato and several species of ornamentals. Minimal differences were found between the nucleocapsid (N) gene amino acid sequences of Australian isolates and these were most closely related to a clade of northern European isolates. CaCV was first detected in Australia in 1999 and is most closely related to Watermelon silver mottle virus, a serogroup IV tospovirus. The natural hosts include capsicum, tomato, peanut and Hoya spp. The virus also occurs in Thailand and Taiwan. IYSV was first found in Australia in 2003, infecting onion and leek, with the distribution in three States suggesting that the virus has been present for some time.
