Resumo: The objective of this work was to evaluate the susceptibility of R. microplus larvae from different oviposition times to fipronil. The LPT was performed in sextuplicate, at concentrations of 18.75, 37.5, 75, 150 and 300 μg.mL-1. The LC50 found for the egg masses incubated with +7, +14 and +21 days were respectively 105.87, 110.71 and 121.22 μg.mL-1. The larvae originating from egg masses from the same group of engorged females, incubated on different days, presented similar mortality rates compared to the evaluated fipronil concentrations, facilitating the maintenance of laboratory colonies of this tick species.

O TPL foi realizado em sextuplicata, nas seguintes concentrações 18,75; 37,5; 75; 150; 300 μg.mL-1. Não houve diferença estatística entre as mortalidades das larvas oriundas de posturas incubadas nos dias mais sete, +14 e +21, expostas ao fipronil. As CL50 encontradas para as posturas incubadas com +7, +14 e +21 dias foram respectivamente 105,87; 110,71 e 121,22 μg.mL-1. Observou-se que as larvas oriundas de posturas, do mesmo grupo de fêmeas ingurgitadas, incubadas em dias diferentes apresentam taxas de mortalidade parecidas frente as concentrações de fipronil avaliadas, facilitando a manutenção das colônias laboratorias desta espécie de carrapato.Sociedade de Medicina Veterinária do Estado do Rio de Janeiro.2023-03-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/xmlhttps://bjvm.org.br/BJVM/article/view/128210.29374/2527-2179.bjvm005922Brazilian Journal of Veterinary Medicine; Vol. 45 (2023); e005922Revista Brasileira de Medicina Veterinária; v. 45 (2023); e0059222527-21790100-2430reponame:Brazilian Journal of Veterinary Medicineinstname:Sociedade de Medicina Veterinária do Estado do Rio de Janeiro (SOMVERJ)instacron:SBMVenghttps://bjvm.org.br/BJVM/article/view/1282/1312https://bjvm.org.br/BJVM/article/view/1282/1313Copyright (c) 2023 Daniela de Oliveira Rocha, Roxanne Marina da Silva Roque, Thiago de Souza Vieira, Brena Gava Guimarães, Ingrid Lins Raquel de Jesus, Marisa Beatriz da Silva Rocha, Fabio Barbour Scott, Barbara Rauta Avelarhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessRocha, Daniela de OliveiraRoque, Roxanne Marina da SilvaVieira, Thiago de SouzaGuimarães, Brena Gavade Jesus, Ingrid Lins RaquelRocha, Marisa Beatriz da SilvaScott, Fabio BarbourAvelar, Barbara Rauta2023-04-12T12:58:31Zoai:ojs.rbmv.org:article/1282Revistahttps://rbmv.org/BJVMONGhttps://rbmv.org/BJVM/oaicontato.rbmv@gmail.com2527-21790100-2430opendoar:2023-04-12T12:58:31Brazilian Journal of Veterinary Medicine - Sociedade de Medicina Veterinária do Estado do Rio de Janeiro (SOMVERJ)false
