Larvicidal activity of Medicinal Plants against Mosquito Vector

Mosquitoes are vector which can able to transmit wide number of diseases like Malaria, Yellow fever, Filariasis, Japanese encephalitis and Chikungunya. In India, the most common disease transmitting Mosquito species are Aedes aegypti, Anopheles stephensi and Culex quinquefasciatus, and they are known to transmit wide number of Vector borne diseases. Use of synthetic Chemical insecticides in Mosquito control results in various harmful effects which includes, Vector resistance, Environmental pollution and Health hazards. Researchers have necessitated the current significance in the search for plant-based insecticide products that are environmentally safe and effective to control mosquito. The present study was aimed to compare the Larvicidal activity of Pedalium murex and Erythrina variegate methanol extracts against Mosquito vectors. It was observed that the increase in concentration of Methanol plant extracts increases the Larvicidal activity of the selected Mosquito larvae. Among the three Mosquito larvae, the Medicinal plant methanol extract showed high mortality percentage against Culex quinquefasciatus followed by Anopheles stephensi and Aedes aegypti.
