[Chemical components of Artemisia scoparia volatile oil and its poison activity to mosquito].
The study showed that Artemisia scoparia contained 0.38% of volatile oil, in which, a total of 38 chemical components were identified, accounting for 87.53% of the substances detected,and 12 kinds of terpenoids compounds were the main components, accounting for 45.04% of the total. The oil had a high and rapid poison activity on Culex pipiens pallens larva and adult. The LC50 value for the larva was 12.5 mg x L(-1) within 2 days, and the mortality of the adult in 24 hours was 70% and 100% when the dosage was 1 and 10 microg x cm(-2).
