Resumo: The objective of this work was to study the biology of Stenoma catenifer under different temperatures, determine its temperature requirements, estimate the number of generations for the city of São Tomás de Aquino, MG, and verify the model in the field. In order to determine duration, viability, fecundity, longevity, and temperature requirements, the insects were reared on cultivar Breda avocado seeds at different temperatures, under 70±10% relative humidity and a 14-hour photophase. Developmental stages and biological cycle (egg-adult) durations were affected by temperature, with higher values at lower temperatures, while viability was highest at temperature ranging from 18oC to 28oC. The lowest temperature development threshold (Tb), and thermal constant (K) for the egg, caterpillar, and pupal stages, and for the egg-adult period were 9.1ºC and 82.3 GD, 8.3ºC and 398.4 GD, 10.1ºC and 164.7 GD, and 8.9ºC and 644.5 GD, respectively. Temperature influenced the egg-laying capacity and longevity of females and males. Based on the normal values of temperature, the numbers of generations per year and per production cycle were 7.8 and 5.1, respectively. The population fluctuation of S. catenifer can be used as an indicator of the number of generations, based on temperature requirements of the pest.

Para a determinação da duração, viabilidade, fecundidade, longevidade e exigências térmicas, criaram-se insetos em sementes de abacate cultivar Breda, em diferentes temperaturas, umidade relativa de 70±10% e fotófase de 14 horas. A duração das fases de desenvolvimento e do ciclo biológico (ovo-adulto) foi afetada pela temperatura, tendo sido maior nas temperaturas mais baixas; a viabilidade foi maior na faixa térmica de 18oC a 28oC. O limiar térmico inferior de desenvolvimento (Tb) e a constante térmica (K) para as fases de ovo, lagarta, pupa e período ovo-adulto foram de 9,1ºC e 82,3 GD; 8,3ºC e 398,4 GD; 10,1ºC e 164,7 GD e 8,9ºC e 644,5 GD, respectivamente. A temperatura influenciou a capacidade de postura e a longevidade de machos e fêmeas. Com base nas normais térmicas, os números de gerações anuais e por ciclo de produção de abacate foram de 7,8 e 5,1, respectivamente. A flutuação populacional de S. catenifer pode ser utilizada como um indicativo do número de gerações, baseada nas exigências térmicas da praga.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraNava, Dori EdsonHaddad, Marinéia de LaraParra, José Roberto Postali2005-10-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/7051Pesquisa Agropecuaria Brasileira; v.40, n.10, out. 2005; 961-967Pesquisa Agropecuária Brasileira; v.40, n.10, out. 2005; 961-9671678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/7051/4099info:eu-repo/semantics/openAccess2010-09-03T13:58:16Zoai:ojs.seer.sct.embrapa.br:article/7051Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-09-03T13:58:16Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
