In order to develop more environmentally benignant insecticides, the
Ligusticum pteridophyllum
Franch. rhizomes essential oil and supercritical fluid (SFE-CO
2
) extract were obtained by two published techniques, hydrodistillation and SFE-CO
2
. The chemical components of this two tested samples were identified by using gas chromatography-mass spectrometry (GC-MS) and gas chromatography-flame ionization detector (GC-FID). Repellent activity and contact toxicity of the obtained samples and myristicin against the adults of
Tribolium castaneum
(Coleoptera: Tenebrionidae),
Lasioderma serricorne
(Coleoptera: Anobiidae), and
Liposcelis bostrychophila
(Psocoptera: Liposcelididae) were compared. Nineteen components were identified in the SFE-CO
2
extract. Twelve components were identified in the
L. pteridophyllum
rhizomes essential oil. SFE-CO
2
extract exhibited higher contact toxicity against
T. castaneum
,
L. serricorne
, and
L. bostrychophila
(LD
50
= 69.60 μg/adult, 14.58 μg/adult, and 1.69 μg/cm
2
, respectively) than that of
L. pteridophyllum
rhizomes essential oil (LD
50
= 87.99 μg/adult, 89.82 μg/adult, and 7.87 μg/cm
2
, respectively). Besides, myristicin (LD
50
= 36.46 μg/adult) showed superior contact toxicity against
T. castaneum
than that of the
L. pteridophyllum
rhizomes essential oil and SFE-CO
2
extract. It possessed potentially practical significance to develop
L. pteridophyllum
rhizomes into plant pesticide or repellent agent for these stored insect controls.
