Pest Identification Guide: Western Flower Thrips Frankliniella occidentalis (Pergande)

Western flower thrips transmits the carmovirus Pelargonium flower break virus (PFBV), the ilarvirus Tobacco streak virus (TSV), and the tospoviruses Chrysanthemum stem necrosis virus (CSNV), Groundnut ringspot virus (GRSV), Impatiens necrotic spot virus (INSV), Tomato chlorotic spot virus (TCSV), and Tomato spotted wilt virus (TSWV). This species is primarily a flower feeder, so most damage would be expected on the flower or fruit. Learn to identify the western flower thrips with this two-page illustrated guide written by Jeffrey D. Cluever and Hugh A. Smith and published by the Department of Entomology and Nematology.

Pest Identification Guide: Melon Thrips Thrips palmi Karny

Melon thrips transmits Calla lily chlorotic spot virus (CCSV), Groundnut bud necrosis virus (GBNV), Melon yellow spot virus (MYSV), Tomato spotted wilt virus (TSWV), and Watermelon silver mottle virus (WSMoV). This species is primarily a foliage feeder (except in pepper and eggplant, where flowers are more preferred). Feeding on the leaves results in yellowing followed by death of leaf. Leaf feeding can also cause terminal growth to be discolored, stunted, and malformed. Feeding on fruit may cause scarring and malformed fruit.

Pest Identification Guide: Chilli thrips Scirtothrips dorsalis Hood

Chilli thrips transmits the ilarvirus Tobacco streak virus (TSV) and the tospoviruses Groundnut bud necrosis virus (GBNV), Groundnut chlorotic fan-spot virus (GCSFV), and Groundnut yellow spot virus (GYSV). This species primarily feeds on young, tender foliage. Feeding on foliage may result in silvering leading to necrosis, leaf curl (upward), distortion, and defoliation. Feeding on the fruit may cause scarring, discoloration, and the formation of corky texture on the fruit. Learn to identify the chilli thrips with this two-page illustrated guide written by Jeffrey D. Cluever and Hugh A. Smith and published by the Department of Entomology and Nematology.
