Resumo: The aim of this study was to compare Larval Immersion Test in syringes, originally proposed by Souza et al. (2008), with two modified bioassays proposed by Silva et al. (2011) and Sindhu et al. (2012). Rhipicephalus (Boophilus) microplus larvae were exposed to nine dilutions of commercial acaricide. After 24 hours, the number of dead larvae was counted. The LC50 for the three methods were 0.186%, 0.125% and 0.153%, respectively. Mortality of larvae exposed to chemical dilutions on Silva et al. (2011) were significantly higher than other methods at lower concentrations, probably in consequence of longer exposure time of larvae to solutions. However, modifications proposed by Sindhu et al. (2012) make technic execution more practical and safer.

(2008), com duas modificações propostas por Silva et al. (2011) e Sindhu et al. (2012). Larvas de Rhipicephalus (Boophilus) microplus foram expostas a nove diluições de acaricida comercial. Após 24 horas, contabilizou-se o número de larvas mortas. A CL50 nos três métodos foi de 0,186%, 0,125% e 0,153%, respectivamente. Houve maior mortalidade de larvas no método de Silva et al. (2011), nas menores concentrações, quando comparado aos demais métodos, provavelmente devido ao maior tempo de exposição das larvas ao composto químico. Entretanto, as modificações propostas por Sindhu et al. (2012) proporcionam maior praticidade e segurança na execução da técnica.UEL2016-10-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionCOMUNICAÇÃO CIENTÍFICAAvaliado por paresapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2276010.5433/1679-0359.2016v37n5p3205Semina: Ciências Agrárias; Vol. 37 No. 5 (2016); 3205-3208Semina: Ciências Agrárias; v. 37 n. 5 (2016); 3205-32081679-03591676-546Xreponame:Semina.
