324 THRIPS AND TOSPOVIRUSES: PROCEEDINGS OF THE 7TH INTERNATIONAL SYMPOSIUM ON THYSANOPTERA 325 The Thysanoptera fauna of Brazil Renata Chiarini Monteiro E-mail: [email protected] Abstract: A brief overview of the Thysanoptera of Brazil is given, with an account of the species recorded and available information on their habitat, distribution and pest status. Introduction schottii (Heeger, 1852) (Phaeothripidae, About 520 Thysanoptera species, in 139 genera Idolothripinae). Very few species of the and six families are known from Brazil. About one- Brazilian fauna were described up to 1930, third of these species are grouped in the suborder and most of the work was done by European Terebrantia and two-thirds in the Tubulifera, and researchers (E. Bergroth, K. Schmutz, R. S. these total about 10% of the known world fauna. Bagnall, H. Priesner, O John and A.C. Morgan). Of these species 370 were described originally A significant contribution to our knowledge from Brazil (Table 1). Changes in classification of of the thrips fauna from Brazil was from North Thysanoptera, as well as species misidentifications American entomologists during 1930 to 1960 and synonymies are also considered. (J.C Crawford, D. Moulton and J.D. Hood). Hood and Moulton described approximately 77% and History of taxonomic studies 12 % of the known species, respectively, this Most taxonomic studies on Thysanoptera comprising almost 90 % of the known valid species in Brazil were carried out by entomologists described originally from Brazil.

But the The first species described from Brazil character states that he used to distinguish species was Thrips schottii, now Elaphrothrips are now outdated (Mound & Marullo, 1996).

Studies focused on the recognition and Gregório de Bondar and Ângelo Moreira da determination of species particularly associated Costa Lima were the first Brazilian entomologists with cultivated plants, and on the organization to dedicate part of their studies to thrips, and of our first collection. However, since there between them described 12 species. However, was no reference collection from which to neither worker was exclusively dedicated to start, and there was no active thysanopterist Thysanoptera and only four of the species in Brazil, the research leader (R.A. Zucchi they described are now considered valid. – ESALQ/USP) invited L.A. Mound to join After 1960, a new and diverse group of his group and help to train new students in this entomologists was formed. This group included L. field. This collaboration has been fruitful, and De Santis and Galego de Sureda from Argentina, has led to new researchers on thrips and the R. zur Strassen from Germany, L. A.

Thysanoptera records from different regions and States in Brazil. The geographical records of species where these crops are grown. Some of the described originally from Brazil are usually early records in the Brazilian literature are not associated with places visited by those reliable because they lack any taxonomic basis, taxonomists working on this group, or to species being named after the particular crop on localities where they had established contact with which they were found using the international collectors or Brazilian institutions. For example, literature on pests (Monteiro et al., 1998). about 25% of the records of Tubulifera and 10% Thysanoptera as pest of crops in Brazil of the Terebrantia are from Nova Teutônia (Santa About 24 species are considered to damage Catarina State), hometown of Fritz Plaumann, cultivated plants in Brazil, and 22 out of them the most active insect collector in our country. are Terebrantia. However, not all of these Because the emphasis in Brazil has been are considered to cause significant economic given to agriculture, records of thrips are more losses to agriculture as a whole (Table 4) extensive for species that are associated with (Monteiro et al., 1995, 1998, 1999a,b, 2001a,b, or are pests of crops, and to localities or areas Monteiro, 2001, Nakahara & Monteiro, 1999).
