Previous issue date: 2016-03-01 / CAPES / The searching for development of sustainable agricultural systems has shown satisfactory results from economic, social and agronomic perspectives. However, it is necessary to evaluate these systems about their impacts on the environment. The knowledge of insect fauna is essential in monitoring the impacts caused by anthropic action, and the Coleoptera order, because it?s the group with biggest richness, has been the focus of many studies that evaluate environmental conditions. Given the above, the objective of this study was to analyze the occurrence of beetles captured per impact trap in the period from November 2014 to November 2015, in three environments with different ecological characteristics, and assess the influence of climatic variables in the occurrence of Scolytinae group. In order to conduct the study, the chosen experimental area is located in the Integrated Agroecological Production System (IAPS), in the municipality of Serop?dica/RJ. Were selected, inside the IAPS, three distinct environments: organic coffee production (OC), agroforestry (AFS) and organic coffee (FF). Climatic data was obtained by an automatic station, of the National Institute of Meteorology (INMET), located in Serop?dica, named Agricultural Ecology Station. In each environment, there were set four ethanolic semifunil model traps. The traps were kept in the field in the period from November 2014 to November 2015, and every seven days the storers containers went replaced and the attractive baits were renewed using commercial ethanol (alcohol 96 ?). The samples were forwarded to the Laboratory of Wood Deterioration and Forestry Entomology, at the Rural Federal University of Rio de Janeiro ? UFRRJ, to perform the triage. The insects were separated by trap and their respective area where they were collected, and then identified. All insects collected were quantified and only the coleoptera were identified at the level of family and subfamily. However, four groups of borers beetles (Cerambycidae, Bostrichidae and, Curculionidae: Platypodinae and Scolytinae) were evaluated separately. The highest number of insects was found in the AFS, followed by the organic coffee and the agroforestry system. Nearly 75% of the trapped borers beetles were Scolytinae. The agroforestry system was the environment with more coleoborers, due to the management carried out in the area, because there is a greater diversity of plant species, thus requiring constant maintenance. Seasonality influenced in the number of Scolytinae in the three environments. The temperature, atmospheric pressure and wind speed influenced the Scolytinae fluctuation only in the organic coffee and the agroforestry system, considering that the composition of the forest fragment provides favorable conditions for its microclimate stability. / A busca por desenvolvimento de sistemas agr?colas sustent?veis tem demonstrado resultados satisfat?rios do ponto de vista econ?mico, social e agron?mico. Entretanto ? necess?rio avaliar tais sistemas quanto aos impactos gerados ao meio ambiente. O conhecimento da entomofauna ? essencial no acompanhamento de impactos causados pela a??o antr?pica e, a Ordem Coleoptera, por ser o grupo de maior riqueza, tem sido alvo de muitos estudos para avalia??o de condi??es ambientais. Diante disto, o objetivo deste trabalho foi analisar a ocorr?ncia de cole?pteros capturados por armadilha de impacto, no per?odo de novembro de 2014 a novembro de 2015, em tr?s ambientes com caracter?sticas ecol?gicas distintas e, avaliar a influ?ncia de vari?veis clim?ticas na ocorr?ncia do grupo Scolytinae. Para a realiza??o do estudo, a ?rea experimental escolhida est? localizada no Sistema Integrado de Produ??o Agroecol?gica (SIPA), no munic?pio de Serop?dica, RJ. Foram selecionados dentro do SIPA tr?s ambientes distintos: produ??o de caf? org?nico (CO), sistema agroflorestal (SAF) e fragmento florestal (FF). Os dados clim?ticos foram obtidos pela esta??o autom?tica do Instituto Nacional de Meteorologia (INMET) localizada em Serop?dica, esta??o Ecologia agr?cola. Em cada ambiente foram instaladas quatro armadilhas etan?licas modelo Semifunil. As armadilhas foram mantidas no campo no per?odo de novembro de 2014 a novembro de 2015 e, a cada sete dias os recipientes armazenadores foram substitu?dos e as iscas atrativas renovadas com etanol comercial (?lcool 96?). As amostras foram encaminhadas ao Laborat?rio Deteriora??o da madeira e Entomologia Florestal da Universidade Federal Rural do Rio de Janeiro - UFRRJ para a realiza??o da triagem. Os insetos foram separados por ?rea e armadilha, de onde foram coletados e, em seguida, identificados. Todos os insetos coletados foram quantificados e, os cole?pteros foram identificados em n?vel de Fam?lia e Subfam?lia. No entanto, quatro grupos de cole?pteros broqueadores (Cerambycidae, Bostrichidae e, Curculionidae: Platypodinae e Scolytinae) foram avaliadas separadamente. O maior n?mero de cole?pteros foi encontrado no sistema agroflorestal seguido do caf? org?nico e do fragmento florestal. Cerca de 75% dos cole?pteros broqueadores registrados foram Scolytinae. O sistema agroflorestal foi o ambiente com maior n?mero de cole?pteros broqueadores, devido ao manejo realizado na ?rea, pois ocorre maior diversidade de esp?cies vegetais, consequentemente, exigindo manuten??o constante. A sazonalidade influenciou no n?mero de Scolytinae nos tr?s ambientes. A temperatura, a press?o atmosf?rica e a velocidade do vento influenciaram na flutua??o de escolit?neos apenas no caf? org?nico e no sistema agroflorestal, considerando que a composi??o do fragmento florestal proporciona condi??es favor?veis para a estabilidade microclim?tica.
