Abstract Vector-borne diseases continue to transmit many dangerous pathogens humans. After decades of continuous use insecticides, types vectors have shown the ability build resistance them. This has necessitated development more efficient and environmentally friendly alternatives in form bioinsecticides. Plants contain a wide range phytochemicals with specific targeting, rapid biodegradability, environmental sustainability variety medicinal properties, making them valuable source biologicals. Moreover, this led highly effective new drugs. study aimed identify active ingredients Ceratonia siliqua L., gathered from two consecutive fruiting seasons which were then divided into C. fresh (CSF), dry (CSd), old (stored) stem (CSO) extracts . Metabolomics profiling was performed using UPLC/MS multivariate data analysis. The resulted tentative identification 54 secondary metabolites. These compounds included flavonoids, phenolic acids, withanolides, terpenoids, phenylpropanoids, etc. CSd showed highest number identified components followed by CSO CSF. % nearly equal negative ion mode for three while positive it order CSF > CSO. several exposure periods, plant methanol research significant insecticidal activity against mosquito larvae, Cx. pipiens , housefly larvae M. domestica (CSd) demonstrated (100 MO%) (LC 50 = 0.09 0.07 mg/ml) following 24- 48-hour post-treatments at 1.0 mg/ml.
