Resumo: | The countryside of Rio Grande do Sul, is in a traditional farm barn, cutting and milk, and in this context, the tick Rhipicephalus (Boophilus) microplus, is responsible for numerous losses, by their direct and indirect damages. Nowadays, resistance to acaricides, affects almost all active ingredients on the market, and there is a lack of data on this process in the region under study. The aim of this study was to understand the evolution of the susceptibility of populations Riphicephalus (Boophilus) microplus to active ingredients for use in immersion and sprinkling on the market during the last decade in the region. To do so, 439 samples of properties were analyzed in the region by tick immersion "in vitro" testing at the Veterinary Doctor s Office (CONSULVET) - Bage / RS. We evaluated the following active ingredients: amitraz, cypermethrin + ethion association, deltamethrin, and from the year 2003, a combination cypermethrin + chlorpyrifos + citronellal, yielding the following averages of efficiency: 64.3%, 83.2%, 43.3 and 82.4% respectively. Upon examining the percentages of samples with ≥ 95% efficiency, we obtained the following results: 1st five-year period (2001-2005) = 50.7%, 38.2%, 16.0% and 38.8%, as in 2 ° five-year period (2006-2010) = 24.2%, 41.7%, 4.5% and 48.9% respectively. The study showed that in the countryside of Rio Grande do Sul, there are populations of R. (B.) microplus resistant to all the principles available for application by dipping or spraying is more serious the situation of deltamethrin. It also found that associations of pyrethroid with phosphorated and citronellal are the most indicated formulations in the present, since there was a significant reduction in the efficiency levels of amitraz, over the five-year periods, especially in the last year, which may be due to the use intensity of this principle in the region and the slow selection of resistant populations. It is, therefore, evident the critical situation of tick resistance to acaricides, even in a region where the climate allows only three annual generations of the ectoparasite, and the need for measures that allow the rational and oriented use of acaricides, and management measures and knowledge about the epidemiology of the tick in the region to exert less selection pressure on populations, favoring the life of the active ingredients on the market. |

Nos dias atuais, a resistência aos acaricidas, atinge quase todos os princípios ativos disponíveis no mercado, e existe uma carência de dados relativos a este processo, na região em estudo. O objetivo deste estudo, foi conhecer a evolução da susceptibilidade de populações de Riphicephalus (Boophilus) microplus aos princípios ativos para uso em imersão e aspersão, existentes no mercado, durante a ultima década, na região. Para isto, foram analisadas 439 amostras, de propriedades da região através do teste in vitro de imersão de teleóginas, no Consultório Médico Veterinário (CONSULVET) Bagé/RS. Foram avaliados, os seguintes princípios ativos: amitraz, associação cipermetrina+ethion, deltametrina e apartir do ano de 2003, uma associação ipermetrina+clorpirifós+citronelal, obtendo-se as seguintes médias de eficácia: 64,3%, 83,2%, 43,3 e 82,4% respectivamente. Quando avaliadas as amostras com percentuais de eficácia ≥ 95%, obteve-se os seguintes resultados: 1° qüinqüênio ( 2001-2005 ) = 50,7%, 38,2%, 16,0% e 38,8%, já no 2° qüinqüênio( 2006-2010 ) = 24,2%, 41,7%, 4,5% e 48,9% respectivamente. O estudo demonstrou que na região da Campanha do RS, existem populações de R. (B.) microplus resistentes a todos os princípios disponíveis para aplicação por imersão ou aspersão, sendo mais grave a situação da deltametrina. Também constatou-se que as associações de piretróides com fosforados e citronelal são as formulações mais indicadas na atualidade, uma vez que ocorreu significativa redução dos níveis de eficácia do amitraz, ao longo dos qüinqüênios, sobretudo no último ano, o que pode ser devido ao uso intensivo desse princípio na região e à lenta seleção de populações resistentes. Evidencia-se, assim, a situação crítica de resistência do carrapato a acaricidas, mesmo em uma região onde o clima permite apenas três gerações anuais do ectoparasito , e a necessidade de medidas que permitam o uso racional e orientado dos carrapaticidas, além de medidas de manejo e conhecimento sobre a epidemiologia do carrapato na região, a fim de exercer menor pressão de seleção nas populações, favorecendo a vida útil dos princípios ativos disponíveis no mercado.application/pdfporUniversidade Federal de PelotasPrograma de Pós-Graduação em ParasitologiaUFPelBRBiologiaAcaricidasCampanhaCarrapatoResistênciaAcaricidesCountrysideTickResistanceCNPQ::CIENCIAS BIOLOGICAS::PARASITOLOGIAAnálise da susceptibilidade de Rhipicephalus (Boophilus) microplus aos acaricidas de contato na última décadaAnalysis of the susceptibility of Rhipicephalus (Boophilus) microplus to acaricides contact in the last decadeinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesishttp://lattes.cnpq.br/8925874553408844http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4783838E2&dataRevisao=nullFarias, Nara Amélia da RosaBranco, Luciano Rocha Fagundes Alvesinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFPel - Guaiacainstname:Universidade Federal de Pelotas (UFPEL)instacron:UFPELORIGINALdissertacao_luciano_rocha_fagundes_alves_branco.pdfapplication/pdf1104758http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/2311/1/dissertacao_luciano_rocha_fagundes_alves_branco.pdfb30cb2cfcf60ed3e4183d926b91986c9MD51open accessTEXTdissertacao_luciano_rocha_fagundes_alves_branco.pdf.txtdissertacao_luciano_rocha_fagundes_alves_branco.pdf.txtExtracted Texttext/plain65564http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/2311/2/dissertacao_luciano_rocha_fagundes_alves_branco.pdf.txt278452fc31d8b0bd7862a71ec0998a45MD52open accessTHUMBNAILdissertacao_luciano_rocha_fagundes_alves_branco.pdf.jpgdissertacao_luciano_rocha_fagundes_alves_branco.pdf.jpgGenerated Thumbnailimage/jpeg1737http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/2311/3/dissertacao_luciano_rocha_fagundes_alves_branco.pdf.jpg28df0b635d48a6319480da31f540f5ceMD53open access123456789/23112023-01-25 15:45:17.713open accessoai:guaiaca.ufpel.edu.br:123456789/2311Repositório InstitucionalPUBhttp://repositorio.ufpel.edu.br/oai/requestrippel@ufpel.edu.br || repositorio@ufpel.edu.br || aline.batista@ufpel.edu.bropendoar:2023-01-25T18:45:17Repositório Institucional da UFPel - Guaiaca - Universidade Federal de Pelotas (UFPEL)false |
