Resumo: | Biological aspects of the parasitoid Trichogramma pretiosum Riley (Hymenoptera: Trichogrammatidae) were studied in eggs of its factitious host, Sitotroga cerealella (Olivier) (Lepidoptera: Gelechiidae), with the objective of obtaining basic information about the biology of this parasitoid under environmental lab conditions. There was no control of temperature, relative humidity and photoperiod with the purpose of simulating the natural conditions of the Submédio São Francisco region, Pernambuco State, Brazil. The mean temperature during the study was 25.9± 0.9 ºC. The results showed a mean duration of the period egg-adult of 9.42 days and a viability of parasited eggs of 88%. The mean number of T. pretiosum emerged by egg of the host was 1.41 with a maximum of two individuals/egg. The mean longevity of females was 5.53 days while the males lived an average of 3.08 days when both were fed with pure honey. |

Não houve controle de temperatura, umidade relativa e fotoperíodo, com o objetivo de simular as condições do Submédio do Vale do São Francisco, Estado de Pernambuco. A temperatura média registrada durante o desenvolvimento do trabalho foi 25,9±0,9 oC. Os resultados mostraram uma duração média do período ovo-adulto de 9,42 dias e uma viabilidade de ovos parasitados de 88%. O número médio de T. pretiosum emergido por ovo do hospedeiro foi de 1,41, com um máximo de dois indivíduos/ovo. As fêmeas viveram, em média, 5,53 dias, enquanto os machos apresentaram longevidade média de 3,08 dias, quando ambos os sexos foram alimentados com mel puro.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraAlencar, José Adalberto deHaji, Francisca Nemaura PedrosaOliveira, José Vargas deMoreira, Andréa Nunes2000-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5943Pesquisa Agropecuaria Brasileira; v.35, n.8, ago. 2000; 1669-1674Pesquisa Agropecuária Brasileira; v.35, n.8, ago. 2000; 1669-16741678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5943/3047info:eu-repo/semantics/openAccess2011-08-26T13:07:43Zoai:ojs.seer.sct.embrapa.br:article/5943Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2011-08-26T13:07:43Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
