ABSTRACT

Mosquito borne diseases are one of the biggest health problem which is threatening the developing countries. Larviciding is a successful way of reducing mosquito densities in their breeding places before they emerge into adults. The present study aims at exploring the larvicidal properties of aqueous extracts of leave, flower and fruit of Moringa oleifera Lam. Larvicidal potential of leave, flower and fruit of Moringa oleifera aqueous extracts were evaluated against third and fourth instar larvae (Aedes aegypti). Aqueous extracts was prepared by maceration technique and the larvicidal assay was carried out at 5 test concentrations of 250,500,750,1000 and 2000μg/ml. Larvicidal potential was determined at 0,1,2,3,4,6,12 and 24 hours and the percentage mortality was calculated. None of the aqueous extracts had found to possess larvicidal property. It can be concluded that, the aqueous extracts of leave, flower and fruit of Moringa oleifera Lam are not suitable for larvicidal properties.
