AB  - With the development of resistance to conventionally used synthetic insecticides, vector management has become very difficult. Hence, scientists have shown interest on botanicals. It is in this regard, present study was aimed to evaluate the efficacy of extracts of <I>Euodia ridleyi </I>leaves against the larvae of vectors of filariasis, malaria and dengue fever vectors namely <I>Culex quinquefasciatus</I>, <I>Anopheles stephensi</I> and <I>Aedes aegypti</I>, respectively employing the standard WHO bioassay method. Non-polar organic solvents such as petroleum ether, ethyl acetate, acetone and methanol were employed for soxhlet extraction. The results project that efficacy of ethyl acetate extract is the most effective among the four solvents. The efficacy was found to be maximum on the larvae of <I>Culex quinquefasciatus</I> with LC<SUB>50</SUB> of 64.59 ppm than the other two species. Similarly the LC<SUB>50</SUB> against <I>Anopheles stephensi</I> and <I>Aedes aegypti</I> were 120.07 and 139.88 ppm, respectively. The data highlights the importance of <I>Euodia ridleyi </I>as a promising local plants with larvicidal potency for further studies to isolate the active molecule in it.
