dc.description.abstract | The study on the toxicity of leaf extracts of Capparis spinosa L. (Capparidaceae) harvested in northern Sahara's Algerian against 3 rd instar larvae of the mosquito 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 fact, the percentage of the maximum mortality is reported for larvae treated with the plant extract concentrated to 100%, 75% and 50% after 24 hours of exposure. While extracts 25% and 15%, they reach the maximum mortality rate (100%) in the fourth and fifth day. This mortality manifest differently extracts 10%, 5% and 1% reaching the maximum rate of about 96.67%, 93.33% and 53.33% respectively at the end of 10th day. The effective concentration 50 (EC 50 ) and the EC90 , estimated value for the 3 rd instar larvae (L 3 ) of Culex pipiens showed that the extract revealed interesting in terms of toxicity, it has an EC50 and EC90 of 0.00041 mg / ml and 0.0037 mg / ml respectively. Evaluation of lethal time 50 (LT 50) and 90 lethal time (LT 90 ), shows that the extract of C. spinosa 100, 75, 50% showed a rapid onset particular against Culex pipiens. Although these results are preliminary, they show a good larvicidal activity of aqueous extracts of leaves of Capparis spinosa. | EN_en |
