| Abstract: | The larvicidal activity of ethanol,
chloroform and hexane soxhlet extracts obtained from S. guttata seeds was investigated against the IVth
instar larvae of Dengue fever vector, Aedes
aegypti and filarial vector, Culex
quinquefasciatus. All extracts including fractions of ethanol extract
exhibited 100% larval kill within 24 hr exposure period at 500 ppm
concentration. Fraction A1 of
ethanol was found to be most promising; its LC50 was 21.552 and 35.520
ppm against C. quinquefasciatus and A. aegypti respectively. Naturally
occurring S. guttata seed derived
fractions merit further study as potential mosquito larval control agents or
lead compounds. |
