Abstract
This research examines the phytochemical constituents and mosquitocidal
efficacy of Carica papaya bark extract against Aedes aegypti, the
principal vector of dengue fever. Phytochemical analysis identified bioactive
substances including flavonoids, alkaloids, tannins, and saponins, recognised
for their insecticidal activities. The extract exhibited considerable
larvicidal, pupicidal, ovicidal, and adulticidal effects in a dose-dependent
manner. Larvicidal experiments demonstrated elevated death rates at minimal dosages,
whilst ovicidal activity revealed suppression of egg hatching. Adulticidal
experiments demonstrated reduced survival and reproductive capacity of exposed
mosquitoes. The results indicate that Carica papaya bark extract is a
viable natural option for regulating Aedes aegypti populations,
providing a sustainable and ecologically safe method to mitigate dengue
transmission. Additional study is advised to identify and delineate the active
components accountable for its mosquitocidal properties.
