Abstract
Mosquito-borne diseases pose a significant
threat to global public health and socio-economic development. Aedes species
mosquitoes, including Aedes vittatus, act as vectors for various
diseases such as dengue fever, chikungunya, zika fever, and yellow fever. In
this study, we aimed to evaluate the larvicidal efficacy of Murraya koenigii
extracts against fourth-instar larvae of Ae. vittatus. The use of
natural products for vector control has gained attention due to the drawbacks
associated with synthetic insecticides. M. koenigii, known as curry
tree, contains bioactive compounds with larvicidal properties. Phytochemical
screening of M. koenigii extracts revealed the presence of alkaloids,
saponins, tannins, flavonoids, and glycosides. The aqueous extracts of leaves,
bark, and roots were prepared and tested against Ae. vittatus larvae.
The larvicidal bioassay followed the World Health Organization guidelines. The
results showed that all three extracts exhibited larvicidal activity. Leaf
extracts demonstrated the highest efficacy, with 88.33 ± 1.15% mortality at the
maximum tested concentration of 400 ppm. Bark and root extracts also exhibited
significant larvicidal activity starting from 200 ppm concentrations.
Concentration-dependent results were observed in all bioassays. The findings
suggest that M. koenigii extracts, particularly leaf extracts, could be
effective in controlling Ae. vittatus larvae. These results support
previous studies demonstrating the larvicidal efficacy of M. koenigii extracts
against different mosquito species. Further research is warranted to identify
and isolate the active compounds responsible for larvicidal activity and assess
the potential of M. koenigii extracts as a sustainable and environmentally
friendly approach for mosquito control.
