Essential oils extracted by steam distillation from Zingiber officinalis was evaluated for larvicidal and repellent activity against the filarial mosquito Culex quinquefasciatus. The larval mortality was observed after 24 h treated for late third instar. The LC50 value was 50.78 ppm. Skin repellent test at 1.0, 2.0, 3.0, and 4.0 mg/cm2 concentration of Z. officinalis gave 100% protection up to 15, 30, 60, and 120 min. These results clearly reveal that the essential oil of Z. officinalis served as a potential larvicidal and repellent agent against filarial vector C. quinquefasciatus.
对通过水蒸气蒸馏法从姜中提取的香精油进行了评估,以测定其对丝虫传播媒介致倦库蚊的杀幼虫活性和驱避活性。对处于三龄晚期的幼虫进行处理24小时后观察幼虫死亡率。半数致死浓度(LC50)值为50.78 ppm。在浓度为1.0、2.0、3.0和4.0 mg/cm² 的姜香精油进行的皮肤驱避试验中,分别在15、30、60和120分钟内提供了100%的防护。这些结果清楚地表明,姜香精油可作为一种针对丝虫传播媒介致倦库蚊的潜在杀幼虫和驱避剂。
