Coleopterans prospection associated to forest ecosystems of Swietenia macrophylla (King), Eastern Amazonia / Prospecção de coleópteros associados a ecossistemas florestais de Swietenia macrophylla (King), Amazônia Oriental

Few research on the entomofauna associated to forest plantations with Swietenia macrophylla (King) in Brazil has been reported. The aim of this study was to analyze the Coleoptera communities in forest ecosystems with S. macrophylla, Brazilian mahogany, with emphasis on the diversity of families and the main functional groups. The insects were collected through pitfall traps in three forest ecosystems: monoculture, consortium and forest enriched with Brazilian mahogany, during dry and rainy periods in two consecutive years. The identification of the captured insects occurred in the entomology laboratory of the Federal Rural University of Amazonia. The analysis was performed through Past Paleontological Statistic 3.14 and ANAFAU, where the difference was considered significant only when p ? 0.05. 11,358 specimens from 21 families were captured, of which 8,058 were sampled in the rainy season and 3,299 in the dry season. There was influence of seasonality and types of forest ecosystems during collection. The families Nitidulidae, Staphylinidae, Carabidae and Meloidae presented greater abundance and richness in the complex ecosystems. Anobiidae, Cerambycidae, Bostrichidae, Brentidae, Buprestidae, Curculionidae, Elateridae, Chrysomelidae and Lagriidae were considered to be pests and common to all studied ecosystems; however, the families Nitidulidae, Scarabaeidae, Tenebrionidae and Passalidae had the function of decomposers; Carabidae, Coccinellidae, Histeridae, Meloidae, Staphylinidae, Cantharidae and Hydrophilidae were the predators.(AU)

Poucas pesquisas sobre a entomofauna associada a plantios florestais com Swietenia macrophylla (King), no Brasil, tem sido reportadas. Pretendeu-se estudar a prospecção de comunidades de Coleópteros em ecossistemas florestais com S. macrophylla, mogno brasileiro, com ênfase na diversidade de famílias e dos principais grupos funcionais. A coleta dos insetos foi através de armadilhas do tipo pitfall traps em três ecossistemas florestais: monocultivo, consórcio e floresta enriquecida com mogno brasileiro, durante os períodos seco e chuvoso em dois anos consecutivos. A identificação dos insetos capturados ocorreu no laboratório de entomologia da Universidade Federal Rural da Amazônia. As análises foram realizadas através dos programas Past Paleontological Statistic 3,14, e ANAFAU, onde a diferença foi considerada significativa apenas quando p ≤ 0,05. Foram capturados 11.358 espécimes de 21 famílias, sendo 8.058 indivíduos no período chuvoso e 3.299 no seco. Houve influência da sazonalidade e dos tipos de ecossistemas florestais durante a coleta. As famílias Nitidulidae, Staphylinidae, Carabidae e Meloidae apresentaram maior abundância e riqueza nos ecossistemas mais complexos. Anobiidae, Cerambycidae, Bostrichidae, Brentidae, Buprestidae, Curculionidae, Elateridae, Chrysomelidae e Lagriidae foram as famílias consideradas pragas e comuns a todos os ecossistemas estudados, entretanto, as famílias Nitidulidae, Scarabaeidae, Tenebrionidae e Passalidae tiveram função de decompositores; Carabidae, Coccinellidae, Histeridae, Meloidae, Staphylinidae, Cantharidae e Hydrophilidae foram os predadores.(AU)
