The hexane, acetone and methanol extracts of mature fruits leaves from Toddalia asiatica was investigated to establish its bio-control potentiality under laboratory condition against fourth instars larvae Dengue vector, Aedes aegypti Filarial Culex quinquefasciatus. Hexane extract T. showed highest larvicidal activity both mosquito vector. LC50 value A. were 37.23, 50.69 125.55 ppm C. quinquefasciatus 33.23, 82.20 215.19 ppm, respectively. Hexane, also potency with values 133.80, 177.20 79.48 164.53, 175.28 87.87 respectively .These results suggested that is promising as larvicide targeted mosquitoes.
