Plant extracts and oils may act as alternatives to conventional pesticides for malaria vector control. The aim of this study was to evaluate the larvicidal activity of essential oils of three plants of Apiaceae family against Anopheles stephensi, the main malaria vector in Iran.
Essential oils from Heracleum persicum, Foeniculum vulgare and Coriandrum sativum seeds were hydro distillated, then their larvicidal activity were evaluated against laboratory-reared larvae of An. stephensi according to standard method of WHO. After susceptibility test, results were analysis using Probit program.
Essential oils were separated from H. persicum, F. vulgare and C. sativum plants and their larvicidal activities were tested. Result of this study showed that F. vulgare oil was the most effective against An. stephensi with LC(50) and LC(90) values of 20.10 and 44.51 ppm, respectively.
All three plants essential oil can serve as a natural larvicide against An. stephensi. F. vulgare oil exhibited more larvicidal properties.
植物提取物和植物油可作为传统杀虫剂的替代品用于疟疾媒介控制。本研究的目的是评估伞形科三种植物的精油对伊朗主要疟疾媒介斯氏按蚊的杀幼虫活性。
对伊朗独活、小茴香和芫荽种子的精油进行水蒸馏，然后根据世界卫生组织的标准方法评估其对实验室饲养的斯氏按蚊幼虫的杀幼虫活性。在敏感性试验后，使用概率程序分析结果。
从伊朗独活、小茴香和芫荽植物中分离出精油并测试了它们的杀幼虫活性。本研究结果表明，小茴香精油对斯氏按蚊最有效，其LC(50)和LC(90)值分别为20.10 ppm和44.51 ppm。
所有三种植物精油均可作为针对斯氏按蚊的天然杀幼虫剂。小茴香精油表现出更强的杀幼虫特性。
