Summary of "Larvicidal and ovicidal activity of carvacrol, p-cymene, and γ-terpinene from Origanum vulgare essential oil against the cotton bollworm, Helicoverpa armigera (Hübner)."

This study evaluated the larvicidal activity, and ovicidal activity of Origanum vulgare EO and its major components against the cotton bollworm, Helicoverpa armigera. The chemical composition of the O. vulgare EO was analyzed by gas chromatography-mass spectroscopy. GC-MS analysis revealed that the O. vulgare EO was composed of ten compounds. The major constituents were carvacrol (78.35%), followed by p-cymene (6.85%) and γ-terpinene (3.70%). In larvicidal activity assay, the O. vulgare EO achieved a LC value of 265.51 μg/ml. The three major constituents from the O. vulgare EO were tested individually for toxicity against larvae of H. armigera. Carvacrol, p-cymene, and γ-terpinene appeared to be most effective against H. armigera, with LC values of 51.53, 121.32, and 150.15 μg/ml, respectively. Moreover, EC values of carvacrol, p-cymene, and γ-terpinene against H. armigera eggs were 33.48, 47.85, and 56.54 μg/ml, respectively. Overall, this study showed that O. vulgare EO and its major constituents have the potential to develop as new eco-friendly insecticides against H. armigera.

Medical and Biotech [MESH] Definitions

A plant genus of the family VERBENACEAE. Lippsidoquinone; TRITERPENES; SESQUITERPENES; and THYMOL have been found in this genus. Plant extracts have cytotoxic activity. It is sometimes called Mexican oregano but that confuses it with real oregano (ORIGANUM).

A plant genus of the family LAMIACEAE that is the source of a familiar food seasoning.

A blood protein (NSILA) which mimics the biological activity of insulin in serum, but is not suppressed by insulin antibodies. During acid-ethanol extraction of Cohn fraction III, 10% of the activity is found in the supernatant (NSILA-S) and the remaining activity in the precipitate (NSILA-P). The latter is a large molecular compound, much less stable than the soluble fraction. NSILA-S is a more potent growth factor than insulin and exhibits sulfation activity.

A quantitative prediction of the biological, ecotoxicological or pharmaceutical activity of a molecule. It is based upon structure and activity information gathered from a series of similar compounds.

Bouts of physical irritability or movement alternating with periods of quiescence. It includes biochemical activity and hormonal activity which may be cellular. These cycles are shorter than 24 hours and include sleep-wakefulness cycles and the periodic activation of the digestive system.
