为了解绒柏Chamaecyparis pisifera精油和日本扁柏Chamaecyparis obtuse精油对蚊虫的生物活性,通过浸渍法测试了两种植物精油对白纹伊蚊Aedes albopictus和致倦库蚊Culex pipiens quinquefasciatus 4龄幼虫及蛹的毒杀活性,采用人体局部涂肤法测试其对白纹伊蚊成蚊的驱避活性,并利用气相色谱-质谱联用仪(GC-MS)定性分析了精油的化学成分。结果表明,绒柏精油和日本扁柏精油对白纹伊蚊4龄幼虫/蛹的24 h LC_(50)分别为47.66/152.33和73.11/205.06 μg/mL,对致倦库蚊4龄幼虫/蛹的24 h LC_(50)分别为31.74/107.61和63.94/131.42 μg/mL。以1.5和2.0 μL/cm~2剂量涂抹人体皮肤,绒柏精油、日本扁柏精油驱...

The insecticidal potential of the essential oils from Chamaecyparis pisifera and Chamaecyparis obtuse were tested against the 4th instar larvae and pupae of Aedes albopictus and Culex pipiens quinquefasciatus using the immersion method. The repellent activity of the essential oils against adults of A. albopictus was assayed by topical application on the skin. The compositions of essential oils were qualitatively analyzed using gas chromatography-mass spectrometry. The 24 h LC_(50) values of C. pisifera and C. obtuse oil against the 4th instar l...
