In the present investigation, the leaf essential oil of Feronia limonia was evaluated for chemical constituents and mosquito larvicidal activity against the larvae of Anopheles stephensi, Aedes aegypti and Culex quinquefasciatus. GC and GC–MS analyses revealed that the essential oil contain 51 compounds. Estragole (34.69 %) and β-pinene(23.59 %) were identified as the major constituents followed by methyl (Z)-caryophyllene (11.05 %), eugenol (6.50 %), linalool (3.97 %), phytol (3.27 %), sabinene (2.41 %) and limonene (2.27 %). Larval mortality was observed after 12 and 24 h of exposure period. The oil showed remarkable larvicidal activity against A. stephensi (LC₅₀ = 38.93 and LC₉₀ = 108.64 ppm (after 12 h); LC₅₀ = 15.03 and LC₉₀ = 36.69 ppm (after 24 h)), A. aegypti (LC₅₀ = 37.60 and LC₉₀ = 104.69 ppm (after 12 h); LC₅₀ = 11.59 and LC₉₀ = 42.95 ppm (after 24 h)) and C. quinquefasciatus (LC₅₀ = 52.08 and LC₉₀ = 124.33 ppm (after 12 h); LC₅₀ = 22.49 and LC₉₀ = 60.90 ppm (after 24 h)). Based on the results, the essential oil of F. limonia can be considered as a new source of larvicide for the control of vector mosquitoes.
