Water-distilled essential oil from the aerial parts of Dipsacus japonicus Miq. (Dipsacaceae) at the flowering stage was analysed by gas chromatography-mass spectrometry (GC-MS). Forty-six compounds, accounting for 96.76% of the total oil, were identified and the main compounds of the essential oil were linalool (11.78%), trans-geraniol (8.58%), 1,8-cineole (7.91%), β-caryophyllene (5.58%), α-terpineol (5.32%), β-selinene (5.15%), and spathulenol (5.04%). The essential oil of D. japonicus possessed contact toxicity against two grain storage insects, Sitophilus zeamais and Tribolium castaneum adults, with LD50 values of 18.32 μg/ adult and 13.45 μg/adult, respectively. The essential oil of D. japonicus also exhibited pronounced fumigant toxicity against S. zeamais (LC50 = 10.11 mg/l air) and T. castaneum adults (LC50 = 5.26 mg/l air). Of the three major compounds, 1,8-cineole exhibited stronger fumigant toxicity than the crude essential oil against S. zeamais and T. castaneum adults with LC50 values of 2.96 mg/l air and 4.86 mg/l air, respectively
