In this test using a concentration of aqueous extract i.e., concentration of 0%, 30%, 40% and 50%. The results from the observation of mortality at 72 hours after application at a concentration of 0% (control) does not happen of death and the criteria of his death is not effective. At a concentration of 30% occurs mortality by 30%, the criteria of death is quite effective. At a concentration of 40% occurs mortality by 40%, the criteria of death is quite effective.
