Tomato spotted wilt virus
Tomato spotted wilt virus (TSWV) is a tospovirus transmitted by some species of thrips. WFT, tomato thrips (Franklienella schultzei) and onion thrips (Thrips tabaci) are common vectors for TSWV in vegetables. Melon thrips (Thrips palmi) is also a vector for TSWV but is not widespread in NSW. Once a plant is infected with TSWV it cannot be cured, so prevention or use of tolerant varieties, if available, are the only management options.
TSWV Description
Tomato spotted wilt virus is one of the most widespread and damaging viruses affecting vegetable crops in Australia. TSWV was first described in Australia in 1915 and has been a sporadic problem since then. The arrival of the very efficient vector WFT has seen an increase in the seriousness of the disease, particularly in hydroponic and covered systems. TSWV causes significant damage to solanaceous vegetables such as tomatoes, potatoes and capsicums, but also to lettuce and a wide range of herbs and ornamental crops. Cucumber infections are symptomless.
TSWV hosts
Many hundreds of plants (>900) are TSWV hosts, most being in the Solanaceae, Asteraceae or Fabaceae. Some show symptoms and some do not. Common weed hosts of both WFT and TSWV include amaranth, cape weed, pigweed, mallows, blue heliotrope, fat hen, purple top, shepherd’s purse, nightshades, Scotch thistle and sow thistle.
How do thrips acquire TSWV?
Thrips larvae must feed on a TSWV-infected plant to acquire the virus. Uninfected adult thrips cannot acquire the virus. Plague thrips and other non-host thrips cannot acquire the virus, nor can other insects such as aphids. TSWV is not spread in seed or via mechanical damage although it can be spread through cuttings used for plant propagation.
