北细辛挥发油对二斑叶螨的毒性及其酶的影响
Effects of Essential Oil from Asarum heterotropoides on Toxicity and Related Enzymes of Tetranychus urticae
摘要
Abstract
To explore new botanical acaricide,the chemical components of Asarum heterotropoides var. mandshuriam essential oils were analysed,and the fumigant toxicity and the effects on related enzymes of the oils to Tetranychus urticae were investigated. In GC-MS analysis,9 major constituents accounting for 86. 1% of the total essential oil, of which methyleugenol (22.9% ) was the most,followed by safrole (19.8% ). Bioassay showed that the essential oils exhibited the most significant toxicity at 8 m/mL air concentration with the mortality was 72.6% ,100% and 100% after 24,48 and 72 h,respectively. In enzyme analysis,4 礸/mL essential oils decreased the activity of Na+ , K+ -ATPase, and increased the activity of glutathione S-transferase during 24 h fumigation. As a conclusion, the essential oils of A heterotro-poides possessed the potential for developing botanical acaricide against T. urticae.关键词
