 en Population Survey And Flight Behavior Of Butterflies (Lepidoptera) In a Forest Portion In São Sepé, RS

Abstract

The objective of this study was to analyze lepidopterous insects with diurnal habits (butterflies) associated with a native forest portion. Eight traps with bananas installed at 1.0, 2.0, 3.0 and 4.0 m above soil surface were used. Samplings were obtained on a weekly basis from December 2005 to December 2006 in the county of São Sepé, RS. The faunistic indices represented by frequency, constancy, abundance and dominance were analyzed. Height of flight and species diversity were also evaluated. A total of 737 individuals of the Nymphalidae family were collected, which were classified into six subfamilies, 16 genus and 21 species. The most representative species were: Euptychia check for this species in other resources sp., Hamadryas feronia check for this species in other resources , Taygetis ypthima check for this species in other resources , Epiphile huebneri check for this species in other resources , Biblis hyperia check for this species in other resources , Taygetis check for this species in other resources sp.1 and Praepedaliodes phanias check for this species in other resources . The diversity indices of Shannon and Margalef indicate greater diversity at the height of 4.0 m and lower diversity at the height of 1.0 m, showing relative abundance as an important parameter in determining diversity. About 70% of the collected species were characterized as frequent, common, non-dominant and of accidental occurrence. Hamadryas feronia and Euptychia sp. were constant, dominant and very frequent. The species Euptychia sp. and Taygetis ypthima had height of flight close to the soil surface.

Keywords
faunistic indices; diversity; fruit trap; height of flight.

Resumo

Com o objetivo de analisar a lepidopterofauna de hábito diurno (borboletas) associada a um remanescente florestal nativo, foram utilizadas oito armadilhas iscadas com banana, instaladas a 1,0, 2,0, 3,0 e 4,0 m do nível do solo. As coletas foram realizadas, semanalmente, de dezembro de 2005 a dezembro de 2006, no município de São Sepé, RS. Foram analisados os índices faunísticos de frequência, constância, abundância e dominância. Também foram avaliadas a altura de voo e a diversidade de espécies. Foram coletados 737 indivíduos pertencentes à família Nymphalidae e distribuídos em seis subfamílias, 16 gêneros e 21 espécies. As espécies mais representativas foram: Euptychia check for this species in other resources sp., Hamadryas feronia check for this species in other resources , Taygetis ypthima check for this species in other resources , Epiphile huebneri check for this species in other resources , Biblis hyperia check for this species in other resources , Taygetis check for this species in other resources sp.1 e Praepedaliodes phanias check for this species in other resources . Os índices de Shannon e de Margalef indicaram maior diversidade para a altura de 4,0 m e menor para a de 1,0 m, constituindo a abundância relativa um parâmetro importante na condução da diversidade. Cerca de 70% das espécies coletadas foram caracterizadas como frequentes, comuns, não dominantes e de ocorrência acidental. Hamadryas feronia e Euptychia sp. foram constantes, dominantes e muito frequentes. As espécies Euptychia sp. e Taygetis ypthima apresentaram alturas de voo mais próximas ao solo.

Palavras-chave
índices faunísticos; diversidade; armadilha de fruta; altura de voo.
