ABSTRACT. Soil invertebrate distribution in Araucaria forest, grassland and edge habitats was studied in both disturbed and undisturbed areas in southern Brazil. Mean-density and taxa compositions were verified. Invertebrate densities differed between grassland and the other two habitats in the undisturbed area but not across the disturbed one. At the disturbed area taxa differed between the grassland and the other two habitats. The undisturbed area, on the other hand, presented taxa differences only between the grassland and the forest habitats. Acari, Arachnida and Collembola were the most sensitive taxa for detecting differences across habitats in both areas. At the disturbed area, these taxa presented densities lowering from the forest to the grassland. At the undisturbed area the same taxa increased from the forest to the grassland. Coleoptera and Formicidae (Insecta) presented no difference between habitats at the studied taxonomic level. KEYWORDS.Araucaria forest, forest edge, grasslands, Acari, Collembola.RESUMO. Invertebrados de solo no mosaico floresta com Araucaria -campos no sul do Brasil: diferenças entre áreas impactadas e não impactadas. A distribuição dos invertebrados de solo entre os em ambientes de floresta com Araucaria, borda-demata e campo, foi analisada em duas áreas no sul do Brasil: uma reserva ecológica e uma propriedade agrícola. A densidade média e a composição dos principais taxa foram verificadas. A densidade total de invertebrados diferiu entre o campo e os outros dois hábitats na área protegida, mas não na fazenda. A composição dos taxa diferiu entre o hábitat de campo e os outros dois habitats na fazenda, e entre o campo e a mata com Araucaria na área protegida. Acari, Arachnida e Collembola foram os grupos que mais apresentaram diferenças entre os diferentes habitats. Na área alterada (fazenda), esses grupos apresentaram diminuição na densidade na direção da floresta com Araucária para o campo, enquanto que na área protegida suas densidades foram maiores no campo do que na floresta com Araucária. Coleoptera e Formicidae (Insecta) não apresentaram diferenças significativas no nível taxonômico estudado.

“…The high proportion of singletons and doubletons surpasses by far those recorded for Pentatomoidea (45%, SCHMIDT & BARCELLOS, 2007) and Coreoidea (32.1%, BARCELLOS et al, 2008) from PET in the same occasions. Sampling method might have influenced this result.…”

“…This trail showed more exclusive species of Pentatomoidea and Coreoidea than Garcia trail as well. SCHMIDT & BARCELLOS (2007) related their result to apparently higher plant heterogeneity along Yucumã trail. Also the higher evenness along this trail suggests that it is more diverse than Garcia.…”

“…Abundance and species richness at PET were also studied in the same occasions for Coreoidea (BARCELLOS et al, 2008) and Pentatomoidea (SCHMIDT & BARCELLOS, 2007). Comparing the four sampling periods, the highest estimated species richness observed for mirids during autumn/2004 was also recorded for coreoids, despite being statistically similar to spring/2003 for that group.…”

A two-year study was carried out to evaluate the composition, abundance and species richness of Miridae from Parque Estadual do Turvo, municipality of Derrubadas, state of Rio Grande do Sul, Brazil. Samplings were made in the springs of 2003 and 2004 (October), and autumns of 2004 and 2005 (May), using a beating tray method, along two trails of the park. Sampling effort (hours x collectors) in the quantitative collections totaled 153 hours. Two-hundred mirid specimens of 50 species were collected. The most abundant mirid was Prepops setosipes (Reuter, 1910), representing 23% of the collected individuals, followed by Collaria capixaba Carvalho & Fontes, 1981 (10.5%) and Tropidosteptes cribratus (Stål, 1860) (7%), the latter recorded in all sampling periods. The highest abundance was observed in the springs of 2003 and 2004, with 53 and 78 individuals, respectively. Rarefaction method showed that estimated species richness was higher in autumn/2004 than in the other sampling periods, and higher along Yucumã than in Garcia trail. Besides a higher species richeness, Yucumã had more exclusive species than Garcia trail. The percent of species represented by one or two specimens in quantitative samplings (singletons and doubletons) was 60%. Additional samplings including hand collection, random beating tray and light trap collections added 20 species not recorded in the quantitative samplings.

“…The insect was recently observed in low numbers on rice before harvest, and on Aeschynomene denticulata Rudd (Fabaceae), a weed in rice fi elds in the state of Santa Catarina (D. Link, personal communication). During autumn 2005, M. curvidens was the most abundant species collected using the beat tray method (63% of total hemipteran species) in a conservation area in the northwestern region of Rio Grande do Sul State (Schmidt & Barcellos 2007). However, there were no complaints from farmers of infestations of this species on cultivated soybean or wheat in areas adjacent to the state park surveyed.…”

Deriva de Insetos e o Caso da Deriva de Mayrinia curvidens (Mayr) (Hemiptera: Pentatomidae) na CostaAtlântica Sul do Brasil RESUMO -A deriva de insetos nas margens de lagos e mares é um fenômeno relativamente comum, embora aparentemente não seja relatado na literatura com freqüência. Procedeu-se a uma revisão sobre a deriva de insetos com ênfase sobre os casos relatados para percevejos (Heteroptera), e especulou-se sobre as possíveis causas para explicar esse fenômeno. O caso impressionante da deriva de populações do pentatomídeo Mayrinia curvidens (Mayr) nas praias do oceano Atlântico no Sul do Brasil é relatado pela primeira vez. Essa deriva, observada previamente em menor intensidade em meados da década de 1970 (A.R. Panizzi, não-publicado), foi constatada novamente em janeiro de 2006 ao longo da costa do Oceano Atlântico no Paraná (latitude 25º 45' S), onde uma população estimada de 16 a 18 milhões de exemplares mortos foram encontrados formando uma faixa de pelo menos 15 km de extensão ao longo da praia. As circunstâncias que ocasionaram esse evento são analisadas em detalhe considerandose dados meteorológicos e o possível aumento das populações do percevejo em plantas hospedeiras cultivadas e não-cultivadas ao longo da costa do Paraná e de Santa Catarina.PALAVRAS-CHAVE: Heteroptera, percevejo, condição atmosférica, vôo de insetos, dispersão, mar ABSTRACT -Insect drift on shore of lakes and seas is a relative common phenomenon although apparently not frequently reported in the literature. Here we review the worldwide occurrence of insect drift with emphasis on Heteroptera, and speculate on possible causes to explain such phenomenon. The dramatic drift of million of specimens of the pentatomid Mayrinia curvidens (Mayr) on the shore of the southern coast of the Atlantic ocean in Brazil is reported for the fi rst time. This drift, previously observed to occur in the mid 70's on the coast of Paraná state with minor intensity (A.R. Panizzi, unpublished) was again observed on January 2006 along the Atlantic coast of Paraná (latitude 25º 45' S), where an estimated population of 16 to 18 million of dead specimens of the bug were observed forming a windrow for at least 15 km along the ocean shore. The circumstances of such event are analyzed in detail considering meteorological data and the possible build up of populations of the bug on cultivated and non-cultivated host plants along the coast of the states of Paraná and Santa Catarina.KEY WORDS: Heteroptera, stink bug, atmospheric condition, insect fl ight, dispersion, seaThe objectives of this paper are to review the literature on the occurrence of insect drift and possible causes and or processes involved in these events. Also, to record an event of insect drift that occurred in a beach in southern Brazil. The occurrence of terrestrial insects in ocean beach drifts forming a windrow for several kilometers along the shore is a rare phenomenon. A brief literature review follows in order to present similar reports on insect drifts worldwide, especially Heteroptera, ...
