Abstract

ZARIDAH, M. Z., NOR AZAH, M. A. & ROHANI, A. 2006. Mosquitocidal activities of Malaysian plants.
Extracts from about 30 species of plants in Malaysia were tested for their ability to kill the larvae or to repel
or knock down the adults of Aedes aegypti, the vector mosquito for dengue and dengue hemorrhagic fever.
Observation of mortality was made after 24 hours of exposure to the plant extract/essential oil to obtain
the median lethal concentration (LC50) of the plant extract/essential oil tested. In repellency and knockdown
effects of adult mosquitoes, median effective concentration (EC50) was obtained after each test. The
three best extracts for killing larvae were the essential oils of Zanthoxylum acanthopodium stem, Aquilaria
malaccensis wood and Pelargonium citrosum plant. For repelling adult mosquitoes, the most effective was the
leaf essential oil of Cymbopogon nardus, followed by that of A. malaccensis. Knock-down ability was best with
mosquito coils made from the seed kernel of Azadirachta indica, followed by the leaf of C. nardus and the
wood of Fernandoa adenophylla.
