Control of Culex quinquefasciatus (Say, 1823) 4^th instar larvae by Azadirachta indica (A. Juss., 1830) and Pongamia pinnata (Pierre, 1898) oil under laboratory condition

Larvicidal test based on different concentrations of neem and karanja oil revealed that both LC₅₀ and LC₉₀ were higher for neem oil. Although both the oils were effective in controlling Culex quinquefasciatus larvae, karanja oil is considered as more effective due to its lower LC₅₀ and LC₉₀. None of these oil inflicted any mortality to non-target test organism Chironomus ramosus.
