The observation showed that 8 thrips species belonged to suborder, Terebrantia viz., Frankliniella schultzei (Trybom), Neohydatothrips samayunkur Kudo, Stenchaetothrips faurei (Bhatti), Thrips florum (Bagnall), Thrips hawaiiensis (Morgan), Thrips palmi Karny, Thrips tabaci Lindeman and Trichromothrips arorai Bhatti and four thrips species suborder belong to the Tubulifera viz., Thrips parvispinus (Karny), Haplothrips ganglbaueri Schmutz, Karnyothrips melaleucus (Bagnall) and Xylaplothrips ligs Ananthakrishnan and Jagadish. During the study, the density of thrip flower ranged from 1.24 to 9.20 and varied with the thrips species, and families of associated host plants. The study showed the presence of two abundant species viz., H. ganglbaueri and T. arorai from many of the host plants. A species of quarantine importance , T. parvispinus was also observed. Key words: Thysanoptera, survey, species diversity, faunistics, abundance, density, flowers Thrips are relatively small insects, belong to the exist there. Keeping this in view, the present study was order Thysanoptera, and subdivided into two suborders undertaken in Western Ghats of Karnataka to know the viz., Terebrantia and Tubulifera.
