REGISTRO DE Frankliniella brevicaulis HOOD (THYSANOPTERA: THRIPIDAE) EM BANANA COMPRIDA (CV. D’ANGOLA) NO ESTADO DO ACRE

Thrips are among the insects harmful to banana cultivation in Brazil, usually depreciating the external aspect of the fruits by the formation of spots or eruptions on their skin, as a result of their food. This work makes the first report of Frankliniella brevicaulis Hood (Thysanoptera: Thripidae) in a commercial plantation of ‘banana comprida’ plantain (cv. D’Angola) in the state of Acre, Brazil. Due to the lack of information about the economic impacts and geographical distribution of this thrips species, research on this subject is strongly recommended in the State.Keywords: Amazon; Phytophagous insect; Terebrantia; Eruption thrips.Tripes estão entre os insetos prejudiciais ao cultivo da banana no Brasil, normalmente depreciando o aspecto externo dos frutos pela formação de manchas ou erupções em sua casca, em consequência da sua alimentação. Este trabalho faz o primeiro relato de Frankliniella brevicaulis Hood (Thysanoptera: Thripidae) em plantio comercial de banana comprida (cv. D’Angola) no estado do Acre. Devido à falta de informações acerca dos impactos econômicos e distribuição geográfica dessa espécie de tripes, pesquisas nesse com esse enfoque são fortemente recomendas no Estado.Palavras-chave: Amazônia, Inseto fitófago, Terebrantia, Tripes-da-erupção

Thrips (Insecta: Thysanoptera) associated to Fabaceae species in the Brazilian Mid-North

Foram coletados tripes em 25 das 40 espécies de fabáceas amostradas em quatro municípios do estado do Maranhão e em dois municípios do estado do Piauí. Foram examinados 818 exemplares de tripes pertencentes a 22 espécies. Doze foram identificadas: Bradinothrips musae (Hood, 1956); Caliothrips phaseoli (Hood, 1912); Dolichothrips indicus (Hood, 1919); Frankliniella brevicaulis Hood, 1937; F. gardeniae Moulton, 1948; F. insularis (Franklin, 1908); F. schultzei (Trybom, 1910); F. tritici (Fitch, 1855); Haplothrips gowdeyi (Franklin, 1908); Heliothrips haemorrhoidalis (Bouché, 1833); Salpingothrips minimus Hood, 1935 e Selenothrips rubrocinctus (Giard, 1901). Cinco são provavelmente novas espécies: Aulacothrips sp.; Frankliniella sp. 3; Hydatothrips sp.; Neohydatothrips sp. e Scolothrips sp. Não foi possível identificar cinco outras espécies, porque o conhecimento taxonômico de um gênero não ainda não está esclarecido (Xylaplothrips Priesner, 1928), porque as espécies pertencem a grupos próximos (Frankliniella sp. 1 e Frankliniella sp. 2) ou devido a diferenças, possivelmente intraespecíficas, com espécies descritas (Plesiothrips sp. e Scirtothrips sp.). Para 17 espécies de fabáceas foram estabelecidos os primeiros registros de associações com tripes. Dolichothrips indicus e Xylaplothrips sp. são novos registros de gêneros no Brasil. Além dessas, B. musae, F. gardeniae, F. tritici, Sa. minimus e Se. rubrocinctus são novos registros para o Meio-Norte do Brasil. Nessa sub-região, indivíduos amarelos e marrons de F. schultzei ocorrem simultaneamente. Foram estabelecidas as primeiras associações de Sa. minimus com espécies vegetais no Brasil. Algumas espécies de tripes conhecidas como pragas de fabáceas, principalmente no sul e sudeste do Brasil, não foram coletadas no Meio-Norte. Uma chave de identificação ilustrada foi elaborada. Os exemplares-testemunhas estão depositados na coleção do Departamento de Entomologia e Acarologia da Escola Superior de Agricultura Luiz de Queiroz, Universidade de São Paulo (ESALQ/USP).Thrips were collected on 25 out of 40 species of Fabaceae sampled in four municipalities in the state of Maranhão and two municipalities in the state of Piaui. A total of 818 thrips specimens, belonging to 22 species, were examined. From those species, twelve were identified: Bradinothrips musae (Hood, 1956); Caliothrips phaseoli (Hood, 1912); Dolichothrips indicus (Hood, 1919); Frankliniella brevicaulis Hood, 1937; F. gardeniae Moulton, 1948; F. insularis (Franklin, 1908); F. tritici (Fitch, 1855); F. schultzei (Trybom, 1910); Haplothrips gowdeyi (Franklin, 1908); Heliothrips haemorrhoidalis (Bouche, 1833); Salpingothrips minimus Hood, 1935 and Selenothrips rubrocinctus (Giard, 1901). Five probably belong to new species: Aulacothrips sp.; Frankliniella sp. 3; Hydatothrips sp.; Neohydatothrips sp. and Scolothrips sp. It was not possible to identify five other species, because the current taxonomic knowledge of one genus is not clear (Xylaplothrips Priesner, 1928) or the species belong to closely related groups (Frankliniella sp. 1 and Frankliniella sp. 2) or due to slight differences, possibly intraspecific, with described species (Plesiothrips sp. And Scirtothrips sp.). For 17 species of Fabaceae, the first records of association with thrips were established. Dolichothrips indicus and Xylaplothrips sp. are new records of genera in Brazil. In addition, B. musae, F. gardeniae, F. tritici, Sa. minimus and Se. rubrocinctus are new species records for the Mid-North. In this area, yellow and brown individuals of F. schultzei occur simultaneously. It was established the first association of Sa. minimus with plant species in Brazil. Some thrips species known as pests in Fabaceae in Brazil, mainly in southern and southeastern, were not found in Mid-North. An illustrated key was elaborated. Voucher-specimens are deposited in the collection of the Department of Entomology and Acarology, Escola Superior de Agricultura \"Luiz de Queiroz\", Universidade de São Paulo (ESALQ/USP)

Systematics of Sericothripinae (Thysanoptera, Thripidae) and taxonomic revision of the Neotropical species

Esta tese é dividida em duas partes: traçar a filogenia de Sericothripinae Karny, 1921 e realizar uma revisão taxonômica das espécies neotropicais. Para a análise filogenética, estados de caracteres morfológicos foram examinados entre Sericothripinae e Thysanoptera-Terebrantia relacionados, e as relações genéricas e supragenéricas foram exploradas. O monofiletismo de Sericothripinae foi recuperado, mas o formato do metasterno, usado na classificação dos gêneros, provavelmente não reflete a filogenia. De acordo com estudos moleculares recentes, o grupo genérico Scirtothrips em conjunto com o gênero Echinothrips Moulton, 1911 foram recuperados como intimamente relacionados aos Sericothripinae, mas, neste trabalho, Psilothrips Hood, 1927 e Pseudothrips Hinds, 1902 foram recuperados como não relacionados com Sericothripinae. Muitos estados de caracteres morfológicos entre os Sericothripinae são considerados homoplásticos e, na ausência de análises moleculares adequadas, alterações formais de nomenclatura não foram realizadas. Na revisão taxonômica, 14 novas espécies de Sericothripinae da região Neotropical são descritas. Chaves ilustradas foram elaboradas para as fêmeas de sete espécies de Hydatothrips Karny, 1913 e 41 espécies de Neohydatothrips John, 1929, principalmente do Brasil, mas incluindo todas as espécies registradas do sul da fronteira entre o México e os EUA até o extremo sul da América do Sul. Espécies de plantas em que associações-hospedeiras foram registradas são indicadas sempre que possível, comentários são elencados para as poucas espécies de importância econômica e uma chave para imaturos de segundo instar de cinco espécies é proposta. Neohydatothrips burungae (Hood, 1935) stat. rev. e N. aztecus Johansen, 1983 stat. rev. são retiradas de sinonímia com N. signifer (Priesner, 1932), ao passo que Sericothrips denigratus De Santis, 1966 syn. n. é sinonimizada com N. burungae. Hydatothrips williamsi (Hood, 1928) comb. n. é realocado de Neohydatothrips e, com isso, houve um caso de homônimo no gênero. Para resolver esse problema, H. tareei nom. nov. é proposto para H. williamsi Mound e Tree, 2009, da Austrália.This work is divided into two main focuses: tracing the phylogeny of Sericothripinae Karny, 1921 and performing the taxonomic revision of their Neotropical species. For the phylogenetic analysis, morphological character states were examined among Sericothripinae and related Thysanoptera-Terebrantia, and generic and suprageneric relationships were explored. The monophyly of Sericothripinae is recovered, but the metasternal shape, as used in the current generic classification, probably does not reflect phylogeny. According with recent molecular studies, the Scirtothrips genus-group together with the genus Echinothrips Moulton, 1911, were recovered as closely related to Sericothripinae, but, in the present work, Psilothrips Hood, 1927 and Pseudothrips Hinds, 1902 were recovered as unrelated to Sericothripinae. Many morphological character states among Sericothripinae are considered homoplasious, and formal nomenclatural changes are deferred in the absence of suitable molecular analyses. For the taxonomic revision, 14 new species from the Neotropics are here described in this subfamily. Illustrated keys are provided to females of seven species of Hydatothrips Karny, 1913, and 41 species of Neohydatothrips John, 1929, mainly from Brazil, but including all recorded species south of the border between Mexico and USA. Plant species on which breeding has been recorded are indicated where possible, notes are provided on the few species of economic importance, and a key is elaborated to second instar immatures. Neohydatothrips burungae (Hood, 1925) stat. rev. and N. aztecus Johansen, 1983 stat. rev. are recalled from synonymy with N. signifer (Priesner, 1932), and Sericothrips denigratus De Santis, 1966 syn. n. is synonymized with N. burungae. Hydatothrips williamsi (Hood, 1928) comb. n. is relocated from Neohydatothrips, and as this produces a homonym in the genus, H. tareei nom. nov. is proposed for H. williamsi Mound and Tree, 2009 from Australia

Thrips on fabaceous plants and weeds in an ecotone in northeastern Brazil

ABSTRACT: Thrips (Thysanoptera) on 33 species of Fabaceae (ornamental and forage) and some weed species were surveyed in areas of caatinga-cerrado ecotone in northeastern Brazil. Twenty species of thrips were identified, all of which are associated for the first time with the plants sampled in this study, totaling 26 new host associations, based on collections of immatures. Five species are probably new to science, illustrating the diversity of thrips in the region. A few thrips species that also occur as pests in other regions of Brazil are discussed. Our data extend the distribution area of thrips species and provide basic information on their associated plants

Glyptothrips fuscipes

<i>Glyptothrips fuscipes</i> (Hood, 1954) <p>(Figs 31–36)</p> <p> This species can be differentiated from most other <i>Glyptothrips</i> species by its brown colouration (including legs, which in other species are usually yellow or at least lighter than the body; Figs 31, 33), and presence of rather thick and elongate capitate setae on all femora and fore tibiae (Fig. 31). Other species in the genus may present this type of thickened setae at least on fore femora (e.g. <i>G. claviger</i>, <i>G. silvaticus</i>), but they are not as elongate and numerous as in <i>G. fuscipes</i>.</p> <p>Known wing forms: micropterous.</p> <p> <b>Specimens studied</b>.

Glyptothrips claviger

<i>Glyptothrips claviger</i> (Hood, 1941) <p>(Figs 14–18)</p> <p> This North American species has a mostly dark brown colouration and occipital setae capitate (Fig. 15), a combination of character states only present elsewhere in <i>G. floridensis</i> —however, the latter has the head lateral setae also thickened and capitate, unlike <i>G. claviger</i>. These two species can be further differentiated by the colouration of antennal segment III, which is a similar shade of brown to other antennal segments in <i>G. claviger</i> (Fig. 18), but bright yellow in <i>G. floridensis</i> (Fig. 28). Further traits which can differentiate these species can be seen in Table 2.</p> <p>Known wing forms: micropterous.</p> <p> <b>Specimens studied</b>.
