SCREENING FOR LARVICIDAL ACTIVITY OF JATROPHA CURCAS PLANT EXTRACTS AGAINST AEDES AEGYPTI.L

Abstract

Jatropha curcas plant is reported to be harmful and resulted as effective insecticide. The different extracts of
Jatropha curcas plant leaf such as aqueous, methanol and acetone were checked on the 3rd in star larvae of dengue vector
Aedes aegypti to perform larvicidal activity. Phytochemical analysis was performed to determine active compounds.
Phytochemical screening showed active presence of alkaloid, flavonoids and steroids in acetone leaf extract. Different
concentrations (0.5, 2.0, 1.0 mg/ml) of the plant extracts were checked against the larvae. Maximum mortality shown in
acetone extract, while methanol extract showed significant mortality after 24 hrs exposure. Hence, these active plant leaf
extracts may be used to control a growth of larvae which causes dengue fever and other diseases.
