Evaluation of mosquitocidal activity of Annona squamosa leaves against filarial vector mosquito, Culex quinquefasciatus Say.
Methanolic extract of leaves of A. squamosa was tested for mosquitocidal effect against C. quinquefasciatus. A liquid mosquito insecticide formulation was prepared with the extract (1, 3 and 5 %w/w) using deodorized kerosene as solvent and investigated for its knock-down and 24 hr mortality. The extract formulation produced dose dependent activity, exhibited significantly shorter knock down KD50 and KD90 values and produced significant mortality. The results suggest the potential mosquitocidal effect of A. squamosa on C. quinquefasciatus.
