The melon fruit fly, Bactrocera zonata (Coquillett) (Diptera: Tephritidae), is a notorious pest, posing significant threat to wide range of fruits and vegetables, leading substantial agricultural losses worldwide. With growing concerns over chemical pesticide resistance environmental safety, plant-based insecticides have emerged as eco-friendly economically sustainable alternatives. In this context, the present study delves into insecticidal potential Ricinus communis extracts against B. zonata. crude extract R. was systematically fractionated using series organic solvents with increasing polarities. fraction demonstrating highest activity further purified for isolation bioactive compounds, employing advanced chromatographic techniques such Column Chromatography, coupled state-of-the-art analytical methods including Gas Chromatography-Mass Spectrometry (GC-MS) Fourier Transform Infrared Spectroscopy (FTIR). Bioassays were conducted on its fractions in n-hexane, methanol, ethyl acetate. Among isolated 11,14,17-Eicosatrienoic acid identified both methanol acetate fractions. This compound exhibited remarkable efficacy, an LC50 value 1.36%, linearity R2 = 0.64, statistically probability (p < 0.01). Particularly, most potent agent highlighting natural insecticide. These findings underscore valuable source compounds management cucurbitae. not only broadens scope pest control strategies but also opens avenues exploration integrated management.
