Resumo: The aim of this study was to determine the potency (ITU) and efficacy of a liquid formulation of Bacillus thuringiensis israelensis developed by the State University of Londrina named BioUel, against early fourth instar larvae of Aedes aegypti and Culex quinquefasciatus. The ITU/mg of BioUel was 960, the LC?? was of 0.271 (? 0.39) ppm, and the LC?? was 0.634 (? 0.099) ppm, in larvae of C. quinquefasciatus. In A. aegypti larvae, LC?? was 0.332 (? 0.042) ppm and LC?? was 0.694 (? 0.073) ppm. The ITU level of BioUel and its control results were similar to most commercial products tested. Stability was of approximately 90 days, which allows for local production.
