This 2-page fact sheet outlines what vegetable growers need to know about Western flower thrips (WFT) and the associated disease Tomato spotted wilt virus (TSWV). Western flower thrips are similar in appearance and biology to onion and tomato thrips, which are common in Australia. However, due to its efficiency at spreading TSWV and the feeding damage it causes, WFT has caused millions of dollars of crop damage overseas and in Australia. This fact sheet provides a broad outline of the management strategies for this pest-disease complex based on work conducted by Australian researchers. Information relevant to the management of Western flower thrips (WFT), Tomato spotted wilt virus (TSWV) and other Thrips and Tospoviruses is included in this item.
