Resumo: | The objective of this study was to evaluate the efficiency, phytotoxicity and residual effect of the aqueous extract of leaves of Prosopis juliflora (Sw.) DC (Fabaceae) for Tetranychus bastosi Tuttle, Baker & Sales (Acari: Tetranychidae) on Jatropha curcas L. (Euphorbiaceae). For the evaluation of the control efficiency, physic nut plants were infested with 30 adult mite females and after 12 days were sprayed with the lethal concentrations (m/v) of the extract (LC50 = 53.45% or CL90 = 85.35%) and with distilled water (control), which corresponded to the treatments. After 24, 48, 72, 96 and 120 hours after application of the extract, two leaves of the lower, middle and upper third of the plants were sampled and the live mites were counted per treatment. The evaluation of the residual effect was done three, 24, 48, 96, 192 and 288 hours after spraying. To evaluate the phytotoxic effect of the extract, scores were given according to the intensity of the symptoms in the plants. Control efficiency was verified throughout the evaluated period, with an average of 81.67% for LC50 and 73.05% for LC90, with no significant difference between the evaluation intervals. The extract had a low residual effect on T. bastosi, but at the end of 12 days the average percentage of oviposition reduction of mite was 49.21% and 68.86% for LC50 and LC90, respectively. The plants did not present phytotoxicity. P. juliflora extract presents potential for the alternative control of T. bastosi in physic nut due to its efficiency on the mortality of this mite, oviposition reduction of females and absence of phytotoxic effect in the plants. |

DC. (Fabaceae) para Tetranychus bastosi Tuttle, Baker & Sales (Acari: Tetranychidae) em Jatropha curcas L. (Euphorbiaceae). Para a avaliação da eficiência de controle plantas de pinhão-manso foram infestadas com 30 fêmeas adultas do ácaro e após 12 dias, foram pulverizadas com as concentrações letais (m/v) do extrato (CL50 = 53,45% ou CL90 = 85,35%) e com água destilada (testemunha), correspondendo aos tratamentos. Decorridas 24, 48, 72 e 96 e 120 horas após a aplicação do extrato, duas folhas do terço inferior, médio e superior das plantas foram amostradas e contabilizou-se os ácaros vivos por tratamento. A avaliação do efeito residual foi feita três, 24, 48, 96, 192 e 288 horas após a pulverização. Para avaliação do efeito fitotóxico do extrato foram atribuídas notas de acordo com a intensidade dos sintomas nas plantas. Constatou-se eficiência de controle por todo período avaliado, com média de 81,67% para a CL50 e 73,05% para CL90, sem diferença significativa entre os intervalos de avaliação. O extrato apresentou baixo efeito residual sobre T. bastosi, mas ao final de 12 dias a porcentagem média de redução da oviposição do ácaro foi de 49,21% e 68,86% para a CL50 e CL90, respectivamente. As plantas não apresentaram fitotoxicidade. O extrato de algarobeira apresenta potencial para o controle alternativo de T. bastosi em pinhão-manso em razão de sua eficiência sobre a mortalidade deste ácaro, redução da oviposição de fêmeas e ausência de efeito fitotóxico nas plantas.Universidade Federal Rural do Semi-Árido2018-10-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/704310.1590/1983-21252018v31n429rcREVISTA CAATINGA; Vol. 31 No. 4 (2018); 1054-1061Revista Caatinga; v. 31 n. 4 (2018); 1054-10611983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/7043/9878Copyright (c) 2018 Revista Caatingainfo:eu-repo/semantics/openAccessNascimento, Maria da Penha Martins doOliveira, Carlos Romero Ferreira deMatos, Cláudia Helena CysneirosBadji, César Auguste2023-07-20T13:57:15Zoai:ojs.periodicos.ufersa.edu.br:article/7043Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:46:32.883766Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
