Larvicidal Effects Of Pongamiaglabra and Syzygiumaromaticum On Aedes Aegypti Mosquito Larvae

Mosquitoes are considered as the most nuisance causing vectors they responsible for a widespread of diseases. Malaria-borne mosquitoes killing two to three million people and infect an estimated hundred or more annually. A host other mosquito-borne diseases including filariasis, yellow fever, dengue, encephalitis kill debilitate hundreds millions more. The present study investigates bio efficacy commercially available plant oils from Pongamia glabra (Karanja) Syzygium aromaticum (Clove). These were tested against Aedes aegypti (Dengue fever mosquito) determine their lethal concentration doses (LC50). larval toxicity assay was performed where stock solution 10% prepared both at range 100 900 ppm 90 1300 set respectively. batch each 10 IVth instar larvae subjected with test, combination control period 24 48 hrs.
