Summary, etc. <span>The present investigation aimed to evaluate the bioefficacy of the essential oil from the leaves of </span><em>Toddalia asiatica </em><span>(L.) Lam. against the dengue vector mosquitoes, </span><em>Aedes aegypti</em><span> L. and </span><em>Aedes albopictus Skuse.</em><span> The essential oil was extracted using Clevenger apparatus and tested at different concentrations (62.5, 125, 250, 500, and 1000 µg/mL) against I, II, III, and IV instar larvae of </span><em>Ae. aegypti</em><span> and </span><em>Ae. albopictus.</em> The larval mortality was recorded after 24 h of treatment. <span>The LC</span><span>50</span><span> values of the essential oil against I, II, III, and IV instar larvae of </span><em>Ae. aegypti </em><span>were 29.90, 31.75, 54.70 and 86.63 µg/mL, respectively and LC</span><span>90</span><span> values were 86.00, 110.97, 296.38 and 500.97 µg/mL, respectively. When tested against I, II, III and IV instar larvae of </span><em>Ae. albopictus</em><span>, the LC</span><span>50</span><span> values were 31.18, 34.40, 64.24, and 98.52 µg/mL, respectively and the LC</span><span>90</span><span> values were 99.61, 251.03, 383.49, and 542.93 µg/mL, respectively. No mortality was observed in control groups of the two mosquito species. The results suggest that the essential oil of </span><em>T. asiatica </em><span>has the potential to be used as an ecofriendly larvicide against </span><em>Ae. aegypti </em><span>and </span><em>Ae. albopictus</em><span>.</span><br />
