The death rates calculated as %, after (2, 4, 8 and 24) hours, the results indicated that the used plant extract had good properties as a larvicide, and the results indicated significant differences at the 5% in the average killing rates for the first and fourth tested larvae, about 67.69% and 36.50%, respectively, the concentration of 1.0% achieved the highest values of 97.82% compared to 29.85% for the concentration of 0.1%. The results also showed that the average death rates % increase with increasing exposure time, reaching 69.50% over 24 hours and 36.63% over two hours.
