The purpose of this study was to evaluate the bioactivity of essential oils extracted from the leaves of Verbena officinalis and Lantana camara L. for the control of Culex pipiens. Triplicate bioassays were performed with fourth larval instars of C. pipiens (n=25 per replicate) with solutions at 1, 5, 10, 50, 100 and 500 μL/L of V. officinalis and L. camara L. extracts. Cumulative mortalities were determined 3, 6, 12 and 24h after treatment. Results showed cumulative mortalities, at three (3) hours to be 30.0 ± 2.9% and 14.8 ± 1.5% and achieve 43.3 ± 1.9% and 44.4 ± 3.1% after 24h exposure time, at 100mg/L of essential oil from L. camara and V. officinalis, respectively.
本研究旨在评估马鞭草和马缨丹叶精油对控制致倦库蚊的生物活性。采用三重复试验，用浓度为 1、5、10、50、100 和 500μL/L 的马鞭草和马缨丹叶精油溶液处理 4 龄幼虫（每个重复 25 只）。处理后 3、6、12 和 24h 测定累计死亡率。结果表明，3h 时，浓度为 100mg/L 的马缨丹叶精油和马鞭草精油的累计死亡率分别为 30.0±2.9%和 14.8±1.5%，24h 时分别达到 43.3±1.9%和 44.4±3.1%。
