The present communication deals with the laboratory studies carried out to ascertain the larvicidal properties of Chlorophytum borivilianum Sant. and Fernand.saponin extracts for the mosquito species Anopheles stephensi, Culex quinquefasciatus and Aedes aegypti. Methanolic extract (ME), crude saponin extract (CSE) and purified saponin fractions (PSF) were used as test solutions. Concentration to kill 50% larvae and concentration to inhibit emergence of 50% adult that is LC50 and EC50 values respectively were calculated. All extracts found to be larvicidal but PSF was found more effective.
Key words: Larvicidal, Chlorophytum borivilianum, saponin.
