Abstract: | The study on the toxicity of leaf extracts of Capparis spinosa L. plant (Capparidaceae) harvested in the northern Sahara, Algerian East against the L 3 larvae of Culex pipiens L. (Diptera, Culicidae). It is noted that larvae of Culex pipiens treated with the aqueous extract Capparis spinosa, a mortality rate which varies with the concentration of extract. In effect the percentage of the maximum mortality is reported for the larvae treated with plant extract concentrated to 100%, 90%, 80%, 70%, 60%, 50%, 40% and 30% mortality rate 100% after five days of exposure. While extracts 20%, 10% where mortality is around 50% and 33.3% respectively were recorded. The CE50% and CE 90% calculated for the third-stage larvae (L 3 ) of Culex pipiens, have shown that the extract has proved advantageous in terms of toxicity, it has in effect an EC 50 and EC90% low, it is 0.08 mg / ml and 0.04 mg / ml respectively. Evaluation of lethal time 50 (LT50% ) and lethal time 90 (TL90% ), shows that the extract of C. spinosa 100%, 90%, 80%, shows a particular speed of action vis-à towards larvae of Culex pipiens. Well what these results are preliminary, they show a good larvicidal activity of aqueous extracts of leaves Capparis spinosa. |
