Thrips species (Insecta, Thysanoptera) inhabiting plants of the Parque Estadual de Itapuã, Viamão, Rio Grande do Sul state, Brazil

Abstract

O presente estudo visa contribuir para o conhecimento da tisanopterofauna do sul do Brasil. Entre junho de 2003 e abril de 2004, foram realizadas saídas de campo para o Parque Estadual de Itapuã (50º50’-51º05’W e 30º20’-30º 27’S), Viamão, Brasil, para a coleta de ramos com e sem flores de diversas espécies vegetais. O material foi levado para laboratório, onde procedeu-se a triagem dos tisanópteros. Foi obtido um total de 23 espécies de tripes, distribuídas em 15 gêneros e duas famílias. Nove destas espécies são novos registros para o Rio Grande do Sul (*) e outras duas para o Brasil (**). As espécies amostradas foram: Aneristothrips claripennis (Moulton, 1933)*, Aurantothrips orchidearum (Bondar, 1931)*, Ceratothripoides lagoenacollus (Moulton, 1933)*, Chaetanaphothrips orchidii (Moulton, 1907)*, Chaetisothrips striatus (Hood, 1935), Coremothrips pallidus Hood, 1925*, Craniothrips urichi Bagnall, 1915, Frankliniella bertelsi (De Santis, 1967), Frankliniella distinguenda Bagnall*, 1919, Frankliniella gardeniae Moulton, 1948*, Frankliniella gemina Bagnall, 1919, Frankliniella insularis (Franklin, 1908), Frankliniella oxyura Bagnall, 1919*, Frankliniella rodeos Moulton, 1933, Haplothrips fiebrigi Priesner, 1931, Hoodothrips lineatus (Hood, 1928), Microcephalothrips abdominalis (Crawford, 1910), Neohydatothrips denigratus (De Santis, 1966)**, Neohydatothrips fasciatus (Moulton, 1938)*, Neohydatothrips flavens (Moulton, 1941), Paraleucothrips minusculus Johansen, 1983**, Smicrothrips particula Hood, 1952, Thrips australis (Bagnall, 1915).

This study is a contribution to the knowledge of the thysanopterofauna of southern Brazil. From June 2003 to April 2004, seasonal field trips were conducted at the Parque Estadual de Itapuã (50º50’-51º05’W and 30º20’-30º27’S), in the county of Viamão, Rio Grande do Sul, to collect shoots with/without flowers of various plant species. The material was brought to the laboratory where the thrips were sorted. A total of 23 thrips species belonging to 15 genera and two families were obtained. Nine of the species resulted as new record for Rio Grande do Sul (*), and other two also for Brazil (**). The species sampled are as follows: Aneristothrips claripennis (Moulton, 1933)*, Aurantothrips orchidearum (Bondar, 1931)*, Ceratothripoides lagoenacollus (Moulton, 1933)*, Chaetanaphothrips orchidii (Moulton, 1907)*, Chaetisothrips striatus (Hood, 1935), Coremothrips pallidus Hood, 1925*, Craniothrips urichi Bagnall, 1915, Frankliniella bertelsi (De Santis, 1967), Frankliniella distinguenda Bagnall*, 1919, Frankliniella gardeniae Moulton, 1948*, Frankliniella gemina Bagnall, 1919, Frankliniella insularis (Franklin, 1908), Frankliniella oxyura Bagnall, 1919*, Frankliniella rodeos Moulton, 1933, Haplothrips fiebrigi Priesner, 1931, Hoodothrips lineatus (Hood, 1928), Microcephalothrips abdominalis (Crawford, 1910), Neohydatothrips denigratus (De Santis, 1966)**, Neohydatothrips fasciatus (Moulton, 1938)*, Neohydatothrips flavens (Moulton, 1941), Paraleucothrips minusculus Johansen, 1983**, Smicrothrips particula Hood, 1952, Thrips australis (Bagnall, 1915).
