Abstract
The present study was conducted to evaluate the larvicidal potential of
the ethanolic leaf extract of Manilkara zapota against mosquito larvae,
which are responsible for transmitting various vector-borne diseases. The
leaves were shade-dried, powdered, and extracted using ethanol through
maceration. The obtained extract was tested for larvicidal activity against the
early third and fourth instar larvae of Aedes aegypti under laboratory
conditions. Different concentrations of the extract were evaluated, and
mortality rates were recorded after 24 and 48 hours of exposure. The results
revealed a concentration-dependent increase in larval mortality, indicating
potent larvicidal efficacy. The LC₅₀ and LC₉₀ values were determined to assess
the effectiveness of the extract. The findings suggest that Manilkara zapota
leaf extract possesses significant larvicidal activity, likely attributed to
the presence of bioactive phytochemicals such as alkaloids, flavonoids, and
terpenoids. Therefore, the plant could serve as a natural alternative for
eco-friendly mosquito control strategies.
