ABSTRACT

The filarial mosquito Culex quinquefasciatus is the most common and the most important mosquito among the genus, Culex occurring mainly in the urban areas, responsible for the spread of filarial worm, Wuchereria bancrofti that causes the dreadful disease called Malabar leg / elephantiasis among human beings. Many methods have been developed to eradicate the mosquito larvae, but often chemicals are being used because of their speedy action. Since they cause so many deleterious effects to environment, many biologically active plant extracts have been studied for their potential efficacy to minimise the extent of pollution caused by synthetic pesticide. Therefore, in the present investigation the efficacy of the leaf extracts of Momordica tuberosa on the larval and pupal period, larval, pupal and adult mortality, percentage of adult emergence and growth index of the filarial mosquito C. quinquefasciatus was carried out. In the sublethal concentrations, prolongation of larval and pupal period and reduction in the percentage of adult emergence were observed.
