摘　　要：采用三角瓶密闭熏蒸法和微量点滴法,分别测定蒜头果油、紫茎泽兰精油、青蒿精油、蓖麻子油、巴豆油和桉树油6种植物精油对赤拟谷盗(Tribolium castaneum Herbst)成虫的熏杀和触杀活性。结果表明,蒜头果油、桉树油对赤拟谷盗成虫具有强烈的杀虫活性,处理24 h后,熏蒸和触杀校正死亡率均达到94%以上;青蒿精油处理48 h后,触杀校正死亡率为94.19%,在100μL/L浓度下熏蒸校正死亡率达83.33%;巴豆油、紫茎泽兰精油和蓖麻子油具有一定的触杀和熏杀作用,但触杀作用均明显强于熏杀作用。Six kinds of plant essential oils including Malania oleifera Chun oil,Eupatorium adenophorum oil,Artemisia annua oil,Ricinus communis seed oil,Croton tiglium oil and Eucalyptus robusta oil were used to treat Tribolium castaneum Herbst,which were determined fumigation and contact activity by triangular bottle closed fumigation method and microdrop method.The results showed that the M. oleifera Chun oil and E. robusta oil had strong insecticidal activity against T. castaneum adults,the corrected mortality rate of fumigation and contact more than 94% for 24 hours. The corrected mortality rate of contact was 94.19% and corrected mortality rate of fumigation was 83.33% under 100 μL/L,when used A. annua oil treatment for 48 hours. Although C. tiglium oil,E. adenophorum oil and R. communis seed oil had a certain insecticidal and fumigation activity. But the insecticidal activity was significantly stronger than the role of fumigation.
