Objective: To analyze the larvicidal effect of the aerial extracts of Ammannia baccifera on\udtwo important mosquito species, Aedes aegypti and Culex quinquefasciatus. Methods: The\udlarval mortality of fourth instar larvae of A. aegypti and C. quinquefasciatus after 24h and 48h\udof treatment were observed separately in control 50, 100, 150, 200, 250, 300, 350, 400, 450 and 500\udmg/L concentrations of the aerial extracts (methanol, ethyl acetate, chloroform) of A. baccifera.\udResults: Based on the probit analysis, the 24h and 48h aerial methanol extract of A. baccifera\udLC\ud50 value of C. quinquefasciatus was found to be in 164.00 mg/L and 107.00 mg/L and LC 90\udvalues for C. quinquefasciatus was found be in 310.00 and 261.00 mg/L. The 24h and 48h aerial\udpart of methanol extract of A. baccifera LC50 value of A. aegypti was found be in 226.00 mg/L and\ud186.00 mg/L and LC90 values was found be in 476.00 and 309.00 mg/L. Conclusions: The results\udindicate that the A. baccifera could be effectively used for the control of mosquito larvae and the\udpossibility of exploiting for the development of commercial larvicides a plant widely occurring in\udIndia
