Population ecology of the multivoltine Neotropical gall midge Eugeniamyia dispar (Diptera, Cecidomyiidae)
Provedor de dados: 76
Autores: Mendonça, Jr.,Milton de S.; Romanowski,Helena P.
Our understanding of the population ecology of insect gallers is largely built on examples from temperate zones, but tropical and subtropical gallers may present distinct patterns of abundance and distribution across time. Eugeniamyia dispar Maia, Mendonça &amp;amp; Romanowski, 1996 is a multivoltine Neotropical cecidomyiid that induces spongy leaf galls on Eugenia uniflora (Myrtaceae). Galls were censused in the urban area of Porto Alegre, southern Brazil on six plants at two sites, for two years, at roughly weekly intervals. Overall 9,694 eggs, galling attempts and galls were counted. New galls continuously appear on developing leaves, but galls with live inducers are absent from June to at least early August. Galls on a same shoot develop...

Thysanoptera: plantas visitadas e hospedeiras no Parque Estadual de Itapuã, Viamão, RS, Brasil
Provedor de dados: 76
Autores: Pinent,Silvia M. J.; Romanowski,Helena P.; Redaelli,Luiza R.; Cavalleri,Adriano.
O conhecimento científico sobre a associação de Thysanoptera com plantas nativas ou cultivadas na região Neotropical é praticamente inexistente. Este trabalho objetivou identificar as espécies de tripes e as plantas por eles visitadas ou utilizadas como hospedeiras em uma unidade de conservação, o Parque Estadual de Itapuã (30°22'S 51°02'W), Viamão, Rio Grande do Sul, Brasil. Entre junho de 1999 e maio de 2001, ramos (n=1.274), flores (n=774) e touceiras de gramíneas (n=596) foram sistematicamente amostradas em 20 pontos em quatro transectos estandardizados. O total de 72 espécies de plantas pertencentes a 26 famílias foram identificadas, 60 das quais foram registradas como hospedeiras. Do total de 9.602 espécimes de tripes, 4.900 (50%) foram registrados...

Thrips species (Thysanoptera) collected at Parque Estadual de Itapuã, Viamão, RS, Brazil
Provedor de dados: 82
Autores: Pinent,Silvia M.J.; Romanowski,Helena P.; Redaelli,Luiza R.; Mound,Laurence A.
The order Thysanoptera comprises mostly phytophagous or fungivorous species, with a few species that are predators. Recent studies have emphasized the diversity of behavioural patterns amongst these diminutive insects. From the 5,500 species known worldwide, about 10% are recorded from Brazil, mostly tropical areas. In this work we surveyed the Thysanoptera fauna of a southern locality, 800 km south of the Tropic of Capricorn. The study site was ''Parque Estadual de Itapuã'' (30°22'S 51°02'W), Viamão, RS, and thrips were sampled from wild flowers, branches, grass and litter, from June 1999 to May 2001. A total of 83 species in 32 genera was found, but only 29 of these species could be identified, emphasizing the poor knowledge of the insect fauna of...

Occurrence of Lepidopterism caused by the moth Hylesia nigricans (Berg) (Lepidoptera: Saturniidae) in Rio Grande do Sul State, Brazil
Provedor de dados: 82
Autores: Iserhard,Cristiano A.; Kaminski,Lucas A.; Marchiori,Maria O.; Teixeira,Eduardo C.; Romanowski,Helena P.
Lepidopterism by Hylesia nigricans (Berg) moth is recorded for the first time in southern Brazil. Preventive strategies of control are proposed based on information on the biology and ecology of this moth.

Population fluctuation, immature mortality and adult longevity of Spartocera dentiventris (Berg) (Hemiptera: Coreidae) on Nicotiana tabacum (Solanaceae)
Provedor de dados: 82
Autores: Canto-Silva,Celson R.; Romanowski,Helena P.
The population fluctuations, mortality in the immature phases and longevity of the Spartocera dentiventris (Berg) adults were studied in an experimental plot of Nicotiana tabacum (Solanaceae) at the Faculdade de Agronomia - Universidade Federal do Rio Grande do Sul, Porto Alegre, RS, Brazil (30º 05' S and 51º 13' W). From November 1996 to March 1997, 30 sampling occasions were carried out: 23 plants were inspected and the number of eggs and nymphs per instar counted and adults marked / recaptured. Mortality in immature bugs was estimated by the difference between the population peaks in successive instars per plants. Parasitism was evaluated based on the egg colour. Two generations developed through the cycle of the crop, the various instars overlapping in...

Borboletas (Lepidoptera, Papilionoidea e Hesperioidea) do Parque Estadual do Espinilho e entorno, Rio Grande do Sul, Brasil
Provedor de dados: 104
Autores: Marchiori,Maria O.; Romanowski,Helena P.
O presente trabalho apresenta uma relação das espécies de borboletas que ocorrem no Parque Estadual do Espinilho (30°11'S, 57°30'W) e entorno no extremo sudoeste do Rio Grande do Sul. Foram realizadas quatro expedições a campo, com duração de cinco dias cada, entre março de 2003 e janeiro de 2004. As amostragens contemplaram áreas com vegetação de Savana Estépica Parque e Mata Ciliar dentro dos limites do parque e entorno. Foi elaborada uma listagem com 97 espécies de borboletas, havendo 10 novos registros para o Rio Grande do Sul.

Species composition and diel variation of a butterfly taxocene (Lepidoptera, Papilionoidea and Hesperioidea) in a restinga forest at Itapuã State Park, Rio Grande do Sul, Brazil
Provedor de dados: 104
Autores: Marchiori,Maria O.; Romanowski,Helena P.
The composition and the hourly variation of butterfly species (Lepidoptera: Papilionoidea and Hesperioidea) throughout the day and the seasons was evaluated in a 1,000 m² patch of sandy forest (Restinga forest) on a coastal plain at Itapuã State Park (30º22'S, 51º02'W), Viamão, Rio Grande do Sul, from July 2001 to June 2002. Butterflies were sampled by scanning and focal observations (adapted from ALTMANN 1974) carried out at successive 45 minutes intervals. This methodology proved to be effective in recording the presence and activity of butterflies on a small area. A total of 108 observation hours yielded 326 butterflies from 41 species, 33 genera and five families. Nymphalidae was the most abundant family contributing with 74% of the total individuals....
