Resumen
Introduction. In recent years, it was discovered that
the Aedes aegypti vector developed a resistance against
chemical-synthetic controls in the Cesar province
and, then, the number of sick people increased.
Objective. Therefore, this study aims to assess
the in vitro effects of the raw extracts of Sapindus
saponaria at different concentrations in the last three
larval stages of A. aegypti. Materials and methods.
Heated ethanol was used for the extraction. Results.
As a result, lethal effects of the 0.9 g/mL of Sapindus
saponaria were found in all of the larval stages during
the first 24 hours of application. Conclusions. In the
process of determining the saponins percentage in the
pure extract by means of the Miller´s sugars hydrolysis
method, a high 1, 3 % ratio of concentration was
obtained, thus confirming the correlation between the
saponins concentration and the larval mortality rate.
