Resumo: The objective of this work was to determine the biology and life table of Tetranychus bastosi on physic nut (Jatropha curcas). The experiment was carried out under controlled conditions at 26ºC and 75% RH, with photophase of 12 hours. The eggs used in the experiments were obtained from stock culture. Evaluations were performed twice a day for the biology of the mite, and once a day for reproductive parameters. The average life cycle of females was 9.63 days and that of males was 8.94 days. The sex ratio was 0.65, and the mean longevity of females was 16 days, with average production of 59 eggs per female. The life table parameters obtained were: liquid reproduction rate (Ro), 45.41 individuals; average generation length (T), 12.66 days; intrinsic growth rate (rm), 0.0538 female per female per day; finite growth rate (λ), 1.023 female per female; and time required for doubling the population (TD), 3.15 days. The spider mite T. bastosi develops well and presents a high reproductive potential on leaves of physic nut.

O experimento foi realizado em ambiente controlado a 26ºC e 75% de UR, com fotófase de 12 horas. Os ovos usados nos experimentos foram oriundos de criação estoque. As avaliações foram realizadas duas vezes ao dia, para a biologia do ácaro, e uma vez, para os parâmetros reprodutivos. O ciclo médio de vida das fêmeas foi de 9,63 dias e o dos machos, de 8,94 dias. A razão sexual foi 0,65 e a longevidade média das fêmeas foi de 16 dias, com produção média de 59 ovos por fêmea. Os parâmetros de tabela de vida obtidos foram: taxa líquida de reprodução (Ro), 45,41 indivíduos; duração média das gerações (T), 12,66 dias; taxa intrínseca de crescimento (rm), 0,0538 fêmea por fêmea por dia; razão finita de aumento (λ), 1,023 fêmea por fêmea; e tempo para duplicação da população (TD), 3,15 dias. O ácaro T. bastosi desenvolvese bem e apresenta alto potencial reprodutivo sobre folhas de pinhão‑manso.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCNPq e CAPESPedro Neto, MarçalSarmento, Renato AlmeidaOliveira, Wennder Parente dePicanço, Marcelo CoutinhoErasmo, Eduardo Andrea Lemus2013-06-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/13660Pesquisa Agropecuaria Brasileira; v.48, n.4, abr. 2013; 353-357Pesquisa Agropecuária Brasileira; v.48, n.4, abr. 2013; 353-3571678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/13660/11344https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/13660/9279https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/13660/9280info:eu-repo/semantics/openAccess2013-06-27T18:15:54Zoai:ojs.seer.sct.embrapa.br:article/13660Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2013-06-27T18:15:54Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
