Plant products are considered to be potential alternatives for chemical pesticides. These to test the larvicidal activity of Aegle marmelos, Coleus aromaticus and Vitex negundo leaf extract are tested against II, III, IV instars and pupa of Culex quinquefasciatus. The LC50 values of V. negundo for II, III, IV instars and pupa is 66.31 ppm, 74.08 ppm, 84.36 ppm and 133.37 ppm respectively. LC50 value obtained for A. marmelos for II, III, IV and pupa is 91.52 ppm, 105.16 ppm, 151.43 ppm and pupa 203.78 ppm respectively. Similarly LC137.77 ppm for II instar, 175 ppm for III instar, 188.36 ppm for IV instar and 221.04 ppm for pupa. Among these three plants studied V. negundo is more effective than other two plant extract. The adult emergence recorded in this study indicates that there a reduction in adult emergence as a function of concentration irrespective of plant extracts studied
