<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ABSTRACT In order to determine the insecticidal potential against Aedes aegypti of the essential oil of the rhizomes of Curcuma longa L., this was extracted by hydrodistillation and its quality evaluated by organoleptic and physicochemical parameters such as refractive index (1,4969), optical rotation (-33,412), density (0,937 3 g/mL) and its ultraviolet and infrared absorption spectra. The oil showed significant larvicidal activity with LC50 lower than 100 mg/L and by the methodologies of bottles and impregnated papers it produced 100% of the knockdown of adult mosquitoes at doses of 50 mg/mL. The processing of the bioassay data was performed using the Probit test of the SPSS statistical program (version 11 for Windows). The results obtained constitute the first characterization of the essential oil of C. longa cultivated in the eastern Cuban region and its insecticidal activity, an ecological and effective alternative for the control of Aedes aegypti mosquitoes.]]></p></abstract>
