Resumo: | The coffee berry borer Hypothenemus hampei (Ferrari) (Coleoptera: Scolytidae) is a pest of coffee and is present in almost all countries producing the crop causing losses of US$ 500 million a year. Despite its importance, nothing is known about her key factor and critical stage of mortality. Therefor, the objective of this study was to determine the critical stage and the key factors of mortality of H. hampei. Data for the making of the life table were collected during five seasons between the months of December 2007 to March 2009 in six coffee plantations between Paula Cândido and Viçosa, MG. The mortalit data of H. hampei were collected weekly and grouped by season and stand, a total of 33 life tables. These 33 life tables were added and taken to mean data which led to an average life table, where the overall mortality was 70.81%. Among the stages of the life cycle of H. hampei, the highest mortality occurred in eggs (29.43%), followed by mortality of third instar larvae (22.22%), second instar larva (18.60%), pupa (18.11%), larva First instar (13.22%) and adults (8.06%) respectively. Mortality factors observed and quantified in this study were parasitism by the wasp-of-uganda Prorops nasuta (Hymenoptera, Bethylidae), predation by predatory bugs of the family Anthocoridae and ants, physiological disorders of eggs (not feasible) larvae and pupae (incomplete ecdysis) and fungal infection by Beauveria bassiana and Metharizium anisopliae. Among these factors, which caused the highest mortality were predation and physiological disorders. The critical mortality level of H. hampei was in larval and the instar critical is the third instar. The key factor of mortality was physiological disorders in larvae (especially in the third instar), followed by mortality due to predation in this stadium. |

Apesar de sua importância, nada se sabe sobre seu fator chave e estágio crítico de mortalidade. Por isso, o objetivo deste estudo foi determinar a fase crítica e os principais fatores de mortalidade de H. hampei. Os dados para a confecção da tabela de vida foram coletadas durante cinco temporadas, entre os meses de dezembro de 2007 a março de 2009 em seis fazendas de café entre Paula Cândido e Viçosa, MG. Os dados de mortalidade de H. hampei foram coletadas semanalmente e agrupadas por época e talhão, totalizando 33 tabelas de vida. Estas tabelas foram somadas e tirada a média dos dados para a confecção da tabela de vida média, onde a mortalidade global foi de 70,81%. Entre as etapas do ciclo de vida de H. hampei, a maior mortalidade ocorreu em ovos (29,43%), seguido pela mortalidade de larvas de terceiro ínstar (22,22%), larva de segundo ínstar (18,60%), pupa (18,11%), larva primeiro ínstar (13,22%) e adultos (8,06%), respectivamente. Os fatores de mortalidade observadas e quantificadas neste estudo foram parasitismo pela vespa-da-uganda Prorops nasuta (Hymenoptera, Bethylidae), a predação por insetos predadores da família Anthocoridae e formigas, distúrbios fisiológicos de ovos (não viáveis) larvas e pupas (ecdise incompleta) e infecção por fungos Beauveria bassiana e Metarhizium anisopliae. Entre esses fatores, o que causou a maior mortalidade foram a predação e distúrbios fisiológicos. O nível crítico de mortalidade de H. hampei ocorreu em larva e o ínstar crítico foi o terceiro ínstar. O fator chave de mortalidade foi de distúrbios fisiológicos em larvas (especialmente no terceiro ínstar), seguido de mortalidade devido à predação neste estádio.Conselho Nacional de Desenvolvimento Científico e Tecnológicoapplication/pdfporUniversidade Federal de ViçosaMestrado em FitotecniaUFVBRPlantas daninhas, Alelopatia, Herbicidas e Resíduos; Fisiologia de culturas; Manejo pós-colheita deTabela de vidaBroca-do-caféCafeeiroManejo cultutalLife tableCoffee berry borerCoffeeManagement cultutalCNPQ::CIENCIAS AGRARIAS::AGRONOMIA::FITOTECNIADinâmica e fatores-chave de mortalidade da broca do café (Hypothenemus hampei)Dynamics and key factors of mortality of the coffee berry borer (Hypothenemus hampei)info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/openAccessreponame:LOCUS Repositório Institucional da UFVinstname:Universidade Federal de Viçosa (UFV)instacron:UFVORIGINALtexto completo.pdfapplication/pdf237644https://locus.ufv.br//bitstream/123456789/4512/1/texto%20completo.pdf62e0ee5cc046b11ad8b24333573f0445MD51TEXTtexto completo.pdf.txttexto completo.pdf.txtExtracted texttext/plain81535https://locus.ufv.br//bitstream/123456789/4512/2/texto%20completo.pdf.txt716cd5c91278e5387692655a17dbf197MD52THUMBNAILtexto completo.pdf.jpgtexto completo.pdf.jpgIM Thumbnailimage/jpeg3570https://locus.ufv.br//bitstream/123456789/4512/3/texto%20completo.pdf.jpg93990e6c00ff783402637b299a5f68e9MD53123456789/45122016-04-10 23:04:17.08oai:locus.ufv.br:123456789/4512Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452016-04-11T02:04:17LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false |
