Adult thrips are slender, elongate and small (less than 1/20 inch.) We are grateful to various research colleagues in the Australian agricultural community for providing some of the tospovirus and feeding damage images below. They cause damage with their feeding and they are very effective vectors of tomato spotted wilt virus. They are usually found in flowers. Because so many tospoviruses affecting tomato cause similar symptoms, it is important to verify the species of tospovirus in question with additional serological and PCR based tools before determinations of the TSWV strain can be made. The identification software used, LucID, is particularly user-friendly. A guide to the key species transmitting Tomato Spotted Wilt Virus in NSW Western flower thrips Onion thrips 5158 Tomato thrips This brochure is a guide to identifying key species of thrips which are vectors of tomato spotted wilt virus (TSWV) in vegetables and ornamentals in NSW. Plague thrips and other non-host thrips cannot acquire the virus, nor can other insects such as aphids. Western flower thrips feed and reproduce on tomato, pepper and eggplant. Thrips as pests. Abstract. An informative PowerPoint presentation that shows the key features that enable identification of Western flower thrips (WFT) versus the other thrips that are commonly found in vegetable crops. Differentially expressed genes in western ower thrips, Frankliniella occidentalis, in response to tomato spotted wilt virus infection were analyzed by RNA-seq [20][21][22] [23]. Thrips have been recognized as primary vectors of tomato spotted wilt virus (TSWV) with Frankliniella occidentalis (Pergande) reported as the most important and efficient vector, while other species such as Thrips tabaci Lindeman also include populations that can vector the virus. Thrips are widespread, in part because they are so small and can be transported long distances through wind, or on plant material.

DNA barcoding as an identification tool for a number of regulated pests -- The major tospoviruses vectored by thrips include: Tomato Spotted Wilt Virus and Impatiens Necrotic Spot Virus. When these larvae feed on the fruit, the damage is called "flecking." Identification of tomato spotted wilt-like virus on watermelon in Taiwan.
