ABSTRACT

There is an urgent need to explore and utilize naturally occurring products for combating harmful agricultural and public health pests. The present study was carried out to evaluate the insecticidal property of the methanol (ME) and water (AqE) extracts of Duranta erecta Linn. leaves against larvae of Culex quinquefascitatus (Say). The extraction was done by using methanol (ME) and water (AqE) as solvents. The preliminary phytochemical screening of the extracts showed the presence of sugars, tannins, saponins, steroids, alkaloids, phenols, flavanoids, glycosides, triterepens and carboxylic acid. Both extracts of D. erecta have larvicidal activity. Between the extracts, ME has more than AqE.
