苦杏仁精油对白纹伊蚊的驱避活性研究

摘要

采用个体涂肤有效保护时间试验研究了苦杏仁精油对白纹伊蚊的驱避活性.结果表明,含HCN和去除HCN的苦杏仁精油对白纹伊蚊都具有很强的驱避活性,涂药8h后,2种苦杏仁精油对白纹伊蚊的驱避率均在96.76％以上,作为对照的隆力奇花露水的驱避率为58.28％.另外,2种精油对人体的有效保护时间分别为6h和7h,高于隆力奇花露水4h.可见苦杏仁精油对白纹伊蚊具有很强的驱避效果,且其有效保护时间高于隆力奇花露水,因而有望开发成为新型的蚊虫驱避剂.%The repellent activity of bitter almond oil with and without HCN and toilet water (with the main component of DEET) against Aedes albopictus were studied with human body. The results showed that both of bitter almond oils had strong repellent activity against A. Albopictus, after 8 h the repellent rate of bitter almond oil with and without HCN was 96. 76% while the repellent rate of toilet water was 58. 28%. The available protective time of two types of bitter almond oil was 6 h and 7 h, respectively, higher than that of toilet water, indicating the potential of bitter almond oil to be developed as a new mosquito repellent agent.
