GC-MS and larvicidal activity of seed aqueous and ethanol extract of Carica papaya against Aedes aegypti (Dengue vector)


P Malathi, S Sujitha

The present study was designed to evaluate the larvicidal activity of aqueous and ethanol extract of Carica papaya against the dengue vector Aedes aegypti. The 4th instar larvae of Aedes aegypti were exposed to various concentrations (1%, 2%,3%,4%, and 5%) for 12 and 24 hrs. Seed ethanol extract of Carica papaya against 4th instar Aedes aegypti after 12 hrs and 24 hrs exposure reveals the most effective larvicidal activity than aqueous extract. The lowest LC50 and LC90 values of seed ethanol at 12 hrs exposures were 1.779 g/100ml and 5.855 g/100ml and 24hrs were 1.298 g /100ml 3.527 g/100ml, respectively. The composition of seed aqueous and ethanol extract of Carica papaya was qualitatively analysed by using GC-MS. The major phytocomponents identified were alcohol (34.68%), ester (39.18%) and Benenepropanoic acid alpha (26.09%),undeconoic acid ethyl ester (8.86%). Results of the present study revealed that the phytocompounds which is present in aqueous and ethanol extract of Carica papaya considered as a potent source for the production of predictable larvicides.
