Abstract: The aim was to study the acricidal activity of six essential oil from Umbelliferae plants against Tetranychus cinabarinus B.. Six essential oils were extracted by steam distillation method from Coriandrum sativum L., Angelicae Dahuricae, Bupleurum chinense, Angelica grosseserratum, Ligusticum jeholense, Ligustici Chuanxiong, respectively. Their acricidal activities were checked by slide-dip method; and chemical constitution were analyzed by gas chromatography mass spectrometry (GC-MS) method. The results show that their half lethal concentration (LC50) were 2.9006 mg/mL, 1.1575 mg/mL, 3.2386 mg/mL, 1.6314 mg/mL, 1.8854 mg/mL, 0.3767 mg/mL, respectively. The chemical constitution of essential oil from L. Chuanxiong contained terpinen-4-ol (11.81% ), bicycle [2.2.1] heptan-2-ol,1,7,7-trimethyl-,2-acetate(8.28% ), 2-methoxy-4-vinylphenol (14.88% ), valerophenone (7.92% ), benzenemethanol, pentyl-1-hexanol (9.87% ). This was the first time to find that the volatile oil of Ligusticum chuanxiong had better acricidal activity for Teranychus cinnabarinus. The acricidal activity was like that of spirodiclofen (LC50=356.8878 mg/L). And terpinen-4-ol might be one of the effective components.
