In this study, the proximate composition and physicochemical analyses were carried out on the larva and extracted oil of ＂Rhynchophorus phoenicis＂. The results showed that the larva contained 0% moisture, 24% crude protein, 6.3% ash, 68.5% fat and 1.2% carbohydrate. The larvas were found to be good sources of minerals. Sodium (832.59 ± 0.5 mg/100g) was the highest, followed in descending order by magnesium (132.7 ± 0.20 mg/100g), calcium (72.4 ± 0.72mg/100g) and potassium (22.89 ± 1.7 mg/100g). The physical properties of the oil extracts showed the state to be semi-solid at room temperature. The oil w as found to contain high levels of unsaturated fatty acids, especially oleic (up to 41.20%) and linoleic (up to 12.50%). The dominant saturated acid was palmitic (up to 31.10%). The oil extracts exhibited good physicochemical properties and could be useful as edible oils and for industrial applications.
