Abstract
Pest infestation is a primary factor
contributing to decreased productivity in both field crops and stored grains.
Although synthetic insecticides and pesticides are commonly used to mitigate
economic losses, their application is associated with adverse effects on human
health and the environment. In light of these concerns, the present study
evaluated the insecticidal potential of an aqueous extract of Murraya
koenigii against Tribolium castaneum. The extract was assessed for
its adulticidal, larvicidal, residual, and repellent activities across five
concentrations (2 ppm > 1.75 ppm > 1.5 ppm > 1.25 ppm > 1 ppm).
Results indicated a significant dose-dependent efficacy in all tested parameters.
The observed bioactivity is likely attributable to the presence of bioactive
phytochemicals, including phenolic compounds such as rutin,
quercetin-3-glycoside, myricetin, and quercetin, along with volatile
constituents like β-caryophyllene, α-cedrene, α-copaene, β-cubebene, and
germacrene D. These findings suggest that M. koenigii may serve as a
promising botanical source for the development of eco-friendly insecticidal
agents targeting T. castaneum, thereby offering a potential alternative
to synthetic chemical pesticides.
