摘要
研究毛莲蒿挥发油对常见储粮害虫赤拟谷盗成虫的生物活性。采用水蒸气蒸馏法提取毛莲蒿挥发油并通过触杀、熏蒸和驱避3种测试方法对生物活性进行评价。结果表明,毛莲蒿挥发油对赤拟谷盗成虫表现出较强的触杀活性(LD_(50)=30.63μg/头)和熏蒸活性(LC_(50)=7.91 mg/L);此外,在高测试体积分数78.63 nL/cm^(2)下分别作用2、4 h后,毛莲蒿挥发油对赤拟谷盗成虫表现出明显的驱避效果(驱避率均为100%)。因此,毛莲蒿挥发油对赤拟谷盗成虫具有较好的防治作用,能为我国储粮害虫的防治提供参考。
The bioactivity of essential oil extracted from Artemisia vestita against Tribolium castaneum was studied in this paper.The essential oil was extracted by means of steam distillation and evaluated by contact,fumigant and repellent activity methods.The essential oil from A.vestita enjoyed strong contact activity(LD_(50)=30.63μg/adult)and fumigant activity(LC_(50)=7.91 mg/L)against T.castaneum;In addition,after 2 and 4 hours treatments,the results showed that the essential oil of A.vestita had obvious repellent effect(78.63 nl/cm^(2))on T.castaneum adults(The repellent rates was 100%).Therefore,it has been concluded that the essential oil of A.vestita enjoys a good control effect on T.castaneum.In this regard,it can provide experimental basis for the control of stored grain pests in China.
