Background & objectives: Mosquitoes transmit serious human diseases, causing millions of deaths
every year and the development of resistance to chemical insecticides resulting in rebounding vectorial
capacity. Plants may be alternative sources of mosquito control agents. The present study assessed the
role of larvicidal activities of hexane, chloroform, ethyl acetate, acetone, and methanol dried leaf and
bark extracts of Annona squamosa L., Chrysanthemum indicum L., and Tridax procumbens L. against
the fourth instar larvae of malaria vector, Anopheles subpictus Grassi and Japanese encephalitis vector,
Culex tritaeniorhynchus Giles (Diptera: Culicidae).
