Essential oil from Ligusticum jeholense and Its Repellent Activity against Two Stored Product Insects
The essential oil extracted from Ligusticum jeholense Nakai et Kitagawa roots and rhizomes with hydrodistillation was investigated by gas chromatography-flame ionization detector (GC-FID) and gas chromatography-mass spectrometry (GC-MS).The main components in the essential oil were 1,3-dimethyl-2,4(1H,3H)-quinazolinedione (33.95%), 3-butylidenephthalide (18.33%), spathulenol (8.90%), bicyclo”2.2.2”oct-5-en-2-ol (7.97%) and myristicin (6.76%).The essential oil were assayed to exhibit repellent activity.At the dose of 78.63 μg/cm2 , the essential oil showed 94% repellency (Class Ⅴ) against the Tribolium castaneum adults after 2 h treatment,while it showed 78% repellency (Class Ⅳ) against the Lasioderma serricorne adults after 2 h treatment.The results indicated that the essential oil have potential for development into natural repellents to control insects in stored products.
