Methanol extracts of 19 indigenous plants were evaluated as mosquito larvicide. Amongthese, pericarp of Zanthoxylum limonella was found to have the most promising larvicidal
properties against Aedes(s) albopictus and Culex quinquefasciatus with LC90 values at 0.47 ppm
and 0.73 ppm, respectively. The extract of Piper nigrum was also found very effective (LC90)
on the larvae of both the species at 6.8 ppm and 8.4 ppm, respectively. The extracts of the
remaining plant parts showed LC90 values at above 100 ppm concentration. Extract of Calotropis
gigantea was found to be the least effective ( LC90 values at 962.8 ppm and 1091.8 ppm) against
the larvae of both the species. However, plant extracts were found more effective against Aedes(s)
albopictus larvae than against Culex quinquefasciatus larvae.
