Objective: To identity and evaluate mosquito larvicidal and repellent activity against\udthe malarial mosquito Anopheles stephensi (A. stephensi) and filarial mosquito Culex\udquinquefasciatus (C. quinquefasciatus).\udMethods: The eggs and egg rafts of A. stephensi and C. quinquefasciatus were procured from\udNational Centre for Communicable Diseases, Mettupalayam, Tamilnadu, India. Filter paper\udattached with eggs was dipped into a plastic tray containing 500 mL of dechlorinated water for\ud30-40 min, long enough to allow the eggs to hatch into larvae.\udResults: The larval mortality was observed for late fourth instar after 24-h treatment. The\udmaximum activity of LC50 value was 0.051 mg/mL and 0.0514 mg/mL for A. stephensi and C.\udquinquefasciatus respectively in essential oil treated at minimum concentration. Skin repellent\udtest at 1.0, 2.0, 3.0 and 4.0 mg/cm2 concentration of Rhizophora mucronata (R. mucronata)\udgave 100% protection up to 11 h. These results clearly revealed the potent larvicidal and\udrepellent activity of R. mucronata essential oil. The present study was conducted to identify\udthe chemical constituents with the GC-MS analysis in the most effective volatile oil of R.\udmucronata.\udConclusions: The results have clearly demonstrated the possibility of transforming the\udpotential natural products into commercial larval and repellent agent after being tested in\uddifferent geo-climates and mosquito species
