Resumo: Rhipicephalus microplus (cattle tick) stands out as one of the most economically important ectoparasites of cattle, but controlling this species has been difficult because populations are resistant to synthetic acaricides. The goal of this study was to evaluate the efficiency of Lecythis lurida extracts, fractions and secondary metabolites against R. microplus. This is the first report of a phytochemical and biological study of L. lurida, which was collected in the cerrado of eastern Maranhão where it is known as sapucarana. In this region, L. lurida stands out for its population density and flowers, which are commonly visited by several bee species. The compounds obtained from L. lurida during this study were triterpenoids, such as friedelanol and friedelin (the major compound), in addition to mixtures of triterpenes and steroids. The evaluation of acaricide activity on larvae and engorged ticks of R. microplus revealed that only some of the extracts and fractions, obtained from the leaves and bark of L. lurida, had moderate activity.

O controle do carrapato bovino tem sido dificultado pela resistência de populações aos acaricidas sintéticos. Dessa forma, o objetivo do trabalho foi avaliar a eficiência carrapaticida de extratos, frações e metabólitos secundários de Lecythis lurida no combate ao R. microplus. Esse é o primeiro relato de estudo químico e biológico da espécie L. lurida, conhecida no cerrado leste do Maranhão, onde foi coletada, como sapucarana. Destaca-se pela sua densidade populacional e também pela exuberância de sua floração, muito visitada por várias espécies de abelhas. A investigação química revelou que os compostos obtidos da espécie L. lurida se agrupam na classe dos triterpenos, entre eles o friedelanol e a friedelina, esse último, como composto majoritário, além de misturas de triterpenos e esteroides. A avaliação da atividade carrapaticida sobre larvas e fêmeas ingurgitadas de carrapatos da espécie R. microplus revelou que apenas alguns extratos e frações apresentaram atividade moderada, considerando como parâmetros as concentrações testadas dos extratos e frações obtidos a frio e a quente de folhas e cascas de L. lurida.Universidade Federal de Santa Catarina2015-09-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2015v28n4p11910.5007/2175-7925.2015v28n4p119Biotemas; v. 28 n. 4 (2015); 119-1302175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2015v28n4p119/30393Copyright (c) 2015 Sinval Garcia Pereira, José Ribamar Silva do Nascimento Júnior, Aldilene da Silva Lima, Livio Martins Costa Junior, Giselle Skelding Pinheiro Guilhon, Lourivaldo da Silva Santosinfo:eu-repo/semantics/openAccessPereira, Sinval GarciaNascimento Júnior, José Ribamar Silva doLima, Aldilene da SilvaCosta Junior, Livio MartinsGuilhon, Giselle Skelding PinheiroSantos, Lourivaldo da Silva2017-10-19T15:52:58Zoai:periodicos.ufsc.br:article/38256Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2017-10-19T15:52:58Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false
