The oviposition behavior of the rare butterfly Minstrellus grandis (Callaghan, 1999) (Lepidoptera: Riodinidae) is recorded for the first time. Two females laid eggs on the old leaves of an unidentified Triplaris Loefl. ex L. (Polygonaceae), a myrmecophytic plant typically known as ‘Triplaria’ or ‘novice’ tree, inhabited by aggressive ‘taxi’ ants of the genus Pseudomyrmex Lund. 1831 (Hymenoptera: Formicidae). These observations suggest that M. grandis caterpillars live associated with one of the most harmful types of Amazon ant-plant symbiosis.

Studies have reported the presence of certain Plusiinae species in both natural and agricultural landscapes, but their turnover in association with agricultural activities remains unexplored. Aiming to understand how the assemblages of Plusiinae are structured by agricultural occupation and climate, this study used automated light traps sampled moths in 18 sites in Brazil, across a broad latitudinal gradient. Our data has demonstrated that climate variables prevails as the most important variables influencing both the composition of Plusiinae and the abundance of its dominant species Chrysodeixis includens. On the other hand, the lack of significance found for the effect of variables representing agricultural occupation evidences that pest species are present both in agricultural and natural ecosystems, also sharing similar abundances at those locations. In other words, instead of following a gradient of agricultural occupation (e.g. crop sizes around sample sites) the composition of these extremely polyphagous insects is more clearly shaped by the latitudinal gradient, in which temperature and precipitation are better predictors. Thus, in contrary to our expectations, pest species inhabits both natural and agricultural landscapes at similar latitudinal sites, probably due to their wide polyphagy spectrum. These results can be used in management and monitoring programs of pest species in South America, since the local abundance variation and species composition can be more reliable predicted by changes in climate conditions.

The widespread cultivation of transgenic soybeans has caused significant changes in the spectrum of Lepidoptera larvae, both in the number of species as well as on their densities in the field. Transgenic crops producing Bacillus thuringiensis (Bt) insecticidal proteins have successfully reduced the incidence of the most common caterpillars infesting soybeans, namely Anticarsia gemmatalis (Lepidoptera: Erebidae) and Chrysodeixis includens (Lepidoptera: Noctuidae). However, lepidopteran species not previously recorded on the crop have been recently found, and are of concern due to the possibility of adaptation to the genetically modified cultivars. The occurrence of Peridroma saucia Hübner (Lepidoptera: Noctuidae) is described for the first time in Brazil feeding on genetically modified soybean cultivars.

Embora a região Belém seja uma das áreas mais exploradas da Amazônia com coletas desde o século XVIII, grande parte das informações se encontra dispersa em coleções internacionais, o que dificulta a reunião de dados e interpretações biogeográficas. Visando ampliar o conhecimento da fauna de lepidópteros da região, o presente estudo levantou uma lista de 225 espécies de Hesperiidae encontradas na RPPN Klagesi durante aproximadamente 24 anos de amostragens esporádicas, embora mais freqüentemente na última década. São adicionadas 113 espécies previamente não relacionadas para a região, a qual passa a ser a área de maior riqueza conhecida de Hesperiidae dentre todas as regiões de endemismo da Amazônia brasileira até então inventariadas. No entanto, o conhecimento da diversidade de Hesperiidae em outras áreas de endemismo é tão restrito, que a riqueza de espécies deve ser utilizada apenas como indicador de esforço amostral ao invés de inferências biogeográficas. Três das regiões de endemismo ainda não apresentam nenhum inventário de fauna (Xingú, Napo e Imeri), enquanto as demais são reconhecidas por um ou poucos inventários. Portanto, para que a lepidopterofauna amazônica seja realmente conhecida e utilizada em estudos de biogeografia e conservação, são necessários esforços direcionados nestas regiões ainda totalmente desconhecidas ou mesmo a reunião de informações sobre coletas já realizadas, cujo material se encontra disperso em coleções pelo mundo. The region of Belém is one of the best known area of the Amazon Forest, given its scientific explorations since the 18th century. However much of the informations about the biological diversity of the region is scattered at several museums around the world, thus making it harder to access and to propose biogeographical hypothesis.. Aiming to contribute to the knowledge of lepidopterological diversity of the region, the present study lists 225 species of Hesperiidae present at Private Natural Reserve Klagesi registered during approximately 24 years of sporadically collecting, although more frequently on the past decade. One hundred and thirteen species not yet registered in endemism's region of Belém are added, which makes it the richest of all Amazonian endemism areas in Brazil. However, the Amazonian skippers are so poorly known that this richness index can only be used for effort comparisons instead of biogeographical or ecological inferences. Three of the endemism regions still lack information about their diversity (Xingú, Napo and Imeri), while others are known basically from one or a few inventories. Therefore, focused sampling at those unknown areas or gathering information at international museums are indispensable strategies to obtain a better knowledge of Amazonian butterfly diversity so they can be used for biogeographical studies and conservation management.

Tendo em vista a ausência de inventários lepidopterológicos no Estado do Acre e sua escassez no bioma amazônico brasileiro, o presente estudo objetivou contribuir para a construção da lista de Hesperioidea e Papilionoidea presentes no Parque Estadual do Chandless, localizado em uma região de difícil acesso e sem infra-estrutura para pesquisa científica. Durante 14 dias foram realizadas coletas com redes entomológicas, armadilhas e técnica de Ahrenholz em diferentes ambientes que caracterizam o parque e seus arredores. Foram identificadas ao total 482 espécies, nenhuma delas presente em listas vermelhas de espécies ameaçadas. É esperado um número significativamente maior de espécies após a adição de novas coletas em outras estações do ano, visto a estimativa Jacknife 1 não atingir sua assíntota, ou mesmo em comparação a inventários em áreas próximas que listam, após um intenso esforço amostral, até cerca de 1700 espécies.

INTRODUCTION: Carbapenem-resistant Pseudomonas aeruginosa (CRPA) has been isolated with increasing frequency in Brazilian hospitals. Since June 2003, its detection in a teaching hospital in the city of Florianópolis, Brazil, has increased. This study aimed to investigate the minimal inhibitory concentration (MIC), presence of Metallo-β-lactamase (MβL) and a possible clonal relationship among the isolates. METHODS: The study included 29 CRPA and seven isolates with reduced susceptibility. The MIC was determined by agar-dilution. Detection of MβL was performed by Double Disk Sinergism (DDS) and Combined Disk (CD). The MβL gene was verified by PCR and nucleotide sequence analysis. Epidemiological typing was performed by pulsed-field gel electrophoresis. RESULTS: Among the 29 carbapenem-resistant isolates, polymyxin B presented 100% susceptibility and piperacillin/tazobactam 96.7%. Seventeen (62%) strains were verified as clonal (A clone) and among these, six isolates indicated phenotypically positive tests for MβL and harbored the blaSPM-1 gene. The first CRPA isolates were unrelated to clone A, harbored blaIMP-16 and were phenotypically positive only by CD. CONCLUSIONS: The spread of a high-level of resistance clone suggests cross transmission as an important dissemination mechanism and has contributed to the increased rate of resistance to carbapenems. This study emphasizes the need for continuous surveillance and improved strategies. INTRODUÇÃO: O isolamento de Pseudomonas aeruginosa resistente aos carbapenêmicos (PARC) tem sido cada vez mais frequente nos hospitais brasileiros. O presente estudo investigou a concentração inibitória mínina (CIM), a presença de metalo-β-lactamases (MβL), e uma possível relação clonal entre PARC isoladas entre junho de 2003 a junho de 2005, em um hospital escola na cidade de Florianópolis, Brasil. MÉTODOS: O estudo incluiu 29 PARC e sete isolados com suscetibilidade reduzida. A CIM foi determinada por diluição em ágar. A detecção de MβL foi realizada por sinergismo de duplo disco (SDD) e disco combinado (DC). Genes para MβL foram pesquisados por PCR e confirmados pela análise da sequência de nucleotídeos. A tipagem epidemiológica foi realizada por gel de eletroforese em campo pulsátil. RESULTADOS: Entre os 29 isolados resistentes aos carbapenêmicos, 100% apresentaram suscetibilidade a polimixina B, e 96,7% a piperacilina/tazobactam. Dezessete (62%) destes isolados pertenciam a um mesmo clone (clone A); entre estes, seis isolados apresentaram testes fenotípicos positivos para MβL e carreavam o gene blaSPM-1. O primeiro isolado PARC não foi relacionado ao clone A, carreava o gene blaIMP-16 e foi fenotipicamente positivo somente por DC. CONCLUSÕES: A propagação de um clone com alto nível de resistência sugere a transmissão cruzada como um importante mecanismo de disseminação e tem contribuído para o aumento nos níveis de resistência aos carbapenêmicos. Este estudo enfatiza a necessidade de vigilância contínua e melhoramento nas estratégias de controle de infecção nesta instituição.
