Larvicidal Activity of Selected Xerophytic Plants Against Culex pipiens and Aedes caspius (Diptera: Culicidae). Pakistan journal of Zoology., vol. 45(1), 241-246.
Methanol extracts of different plants namely, Trichodesma africanum (Boraginaceae), Cleome
rupicola (Capparceae) and Ochradenus baccatus (Resedaceae), were tested for larvicidal activity against 4th instar
larvae of Aedes caspius and Culex pipiens mosquitoes. All plant extracts tested against Ae. caspius showed 100%
mortality at 10µg/ml except the stem of O. baccatus which showed 90% mortality. However, most of the plant
extracts tested against Cx. pipiens showed more than 50% mortality at 10µg/ml. Ae. caspius reported lower LD50 than
Cx. pipiens. The LD50 of the extracts tested ranged between 5.3-0.99. The lowest LD50 calculated against Ae. caspius
was 1.2±0.06 and 0.99±0.16 µg/ml for the stem of T. africanum and C. rupicola, respectively. In conclusion, we have
documented promising larvicidal potential of xerophytic plants, which could be considered as a potentially alternative
source for developing novel larvicides to be used in controlling vectors of mosquito-borne diseases.
