Mallick S., Banerjee R, and Chandra G., 2015, Mosquito larvicidal potential of ethanol leaf extract of the plant, Annona reticulata L. against Aedes aegypti L. and Culex quinquefasciatus Say (Diptera: Culicidae), Journal of Mosquito Research, Vol.5, No.19 1-7 (doi: 10.5376/jmr.2015.05.0019)

The larvicidal potential of ethanol leaf extract of Annona reticulata L. (A. reticulata), ( Annonaceae) was evaluated against 1st - 4th instars larvae of Aedes aegypti L. (Ae. aegypti) and Culex quinquefasciatus Say (Cx. quinquefasciatus) mosquitoes at 24, 48 and 72 h exposure. The extract was found more effective against Cx. quinquefasciatus than Ae. aegypti larvae and its LC₅₀ and LC₉₀ values gradually decreased with increased period of exposure. LC₅₀ values of the extract recorded after 24 h of exposure were 0.5021, 2.9374, 4.2048, 6.2245 ppm respectively against 1st- 4th larvae of Cx. quinquefasciatus and 6.8839, 5.9929, 14.5745, 19.8836 ppm against Ae. aegypti larvae. No mortality and any abnormal behavior up to 72 h post exposure were observed in aquatic non target organisms viz., Chironomus circumdatus larvae, Diplonychus annulatum  and tadpoles of frog when exposed to 24 h LC50 dose of the extract against 3rd instar larvae of Cx. quinquefasciatus. In conclusion, the ethanol leaf extract of A. reticulata exhibited excellent larvicidal activity against Cx. quinquefasciatus and Ae. aegypti mosquitoes.
