Aim of the present study was to evaluate larvicidal and pupicidal properties of Phytolacca dodecandra
plant extracts against immature filarial vector, Culex quinquefasciatus. The powdered berries were extracted with
petroleum ether, acetone, benzene, methanol and water. The crude residue obtained from the extraction was used to
prepare 62.5, 125, 250, 500 and 1000 ppm concentration, respectively. The experiment was conducted by using
standard WHO protocol with modifications. The immature mosquitoes were exposed to selected concentration and
the percentage mortality was observed continuously for 12, 24 and 48 h, respectively. Among the various solvent
extracts tested, petroleum ether, acetone and benzene showed maximum mortality at 125 ppm concentration and
above. At 1000 ppm concentration, all the solvent extracts tested showed 100% mortality. The III-instar larva was
highly susceptible compared to IV-instar and pupa. The water and methanol extract was also proved to have
larvicidal and pupicidal properties. This study showed P. dodecandra plant extract have bioactivity compound to kill
the immature Cx. quinquefasciatus. These plants are growing naturally in Ethiopian highlands and proper utilization
may prevent unwanted pollution to the environment.
