Resumo: The objective of this work was to evaluate the characteristics of cedar plants (Cedrela fissilis) attacked by pests, the resultant damages, and the conditions in which the damage was more pronounced. A census of cedar individuals was conducted by going through a total area of 5.55 hectares of native forest in the municipality of Silveira Martins, in the state of Rio Grande do Sul, Brazil. Cedars with total height greater than 15 cm and collar diameter less than 12 cm were measured, and their pest status was evaluated. Frequency histograms of the collar diameter were made, and the hypsometric relationship of attacked and healthy trees was evaluated by analysis of covariance. For the spatial analysis of individuals, maps of cedar density and maps for risk assessment of sawyer beetle and moth were made. Trees with the greatest probability of being attacked were those with collar diameter between 2 and 6 cm. The clearings and areas with low total density of trees were the most susceptible ones to attacks of the Hypsipyla grandella caterpillar, and locations with high density of individuals whose collar diameter is between 8 and 12 cm are the most susceptible ones to the attacks of Oncideres sp. larvae.

Realizou-se um censo dos indivíduos de cedro por caminhamento em uma área total de 5,55 ha de floresta nativa, no município de Silveira Martins, RS. Cedros com altura total superior a 15 cm e diâmetro do coleto inferior a 12 cm foram medidos, e foi avaliado seu estado fitossanitário em relação às pragas. Foram confeccionados histogramas de frequência de diâmetro do coleto, e analisou-se a relação hipsométrica das árvores atacadas e sadias por meio da análise de covariância. Para a análise espacial dos indivíduos, foram feitos mapas de densidade de cedros e mapas de taxa de risco do serrador e da mariposa. As árvores com maior probabilidade de ataque foram aquelas com diâmetro de coleto entre 2 e 6 cm. As clareiras ou áreas com baixa densidade total de árvores foram as áreas mais suscetíveis aos ataques da lagarta Hypsipyla grandella, e locais com elevada densidade de indivíduos cujo diâmetro de coleto mede entre 8 e 12 cm são os mais suscetíveis ao ataque de larvas do Oncideres sp.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCoordenação de Aperfeiçoamento de Pessoal de Nível Superior (Capes)Pereira, Lílian DanielFleig, Frederico DimasMeyer, Evandro AlcirLanzarin, KarinaWolf, Karina2016-08-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/20721Pesquisa Agropecuaria Brasileira; v.51, n.5, maio 2016: Número Temático Pesquisa, Desenvolvimento e Inovações em Face de Ameaças Sanitárias para a Agropecuária; 607-614Pesquisa Agropecuária Brasileira; v.51, n.5, maio 2016: Número Temático Pesquisa, Desenvolvimento e Inovações em Face de Ameaças Sanitárias para a Agropecuária; 607-6141678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/20721/13324https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/20721/12901Direitos autorais 2016 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2016-08-10T14:29:22Zoai:ojs.seer.sct.embrapa.br:article/20721Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2016-08-10T14:29:22Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
