Abstract The aim of this work was to study the essential oil effect of Ruta graveolens used in traditional medicine and cultivated in the Tebessa (Northeast Algeria) and to evaluate its potential larvicidal activity against fourth instar larvae of Culiseta longiareolata (Aitken, 1954). A total of 25 fourth instar larvae of Culiseta longiareolata were exposed to a variety of concentrations (0.5–25 ppm) in laboratory following the standard procedure of the World Health Organization. The effects were examined on the mortality, biometrical, the biochemical composition (proteins, lipids, and carbohydrates) and the activities of glutathione S-transferase (GST), gluhatione (GSH) rate of larvae body. The EO yield calculated from the dry matter of the aerial part of the plant was 1.78 ± 0.07% and is found to exhibit insecticidal activity against fourth instar larvae with a concentration–response relationship. Moreover, fourth-instar larvae of Culiseta longiareolata is treated using two lethal concentrations (LC25 and LC50) of essential oil and then individual survivals are subjected to a biometrical and biochemical study. It is found that the compound interferes with the growth in reduce the body volume and the main biochemical contents (proteins, carbohydrates and lipids) of different periods are affected. Both concentrations (CL25 and LC50) cause an activation of the detoxification system by an increase in the GST activity and a decrease in the rate of GSH. Therefore, essential oil of a plant (Ruta graveolens) is suggested as botanicals for controlling mosquito larvae.

芸香(Ruta Graveolens)精油对 Culiseta longiareolata 的死亡率、发育、生化和生物标志物的影响

摘要 这项工作的目的是研究在 Tebessa(阿尔及利亚东北部)种植的传统医学中使用的 Ruta Graveolens 的精油作用,并评估其对 Culiseta longiareolata 的四龄幼虫的潜在杀幼虫活性(Aitken,1954)。按照世界卫生组织的标准程序,在实验室中将总共 25 只 Culiseta longiareolata 的四龄幼虫暴露于各种浓度(0.5-25 ppm)。对幼虫体的死亡率、生物特征、生化成分(蛋白质、脂质和碳水化合物)和谷胱甘肽S-转移酶(GST)的活性、谷胱甘肽(GSH)率的影响进行了检查。根据植物地上部分的干物质计算的 EO 产量为 1.78 ± 0。07% 并被发现对四龄幼虫表现出杀虫活性,呈浓度-反应关系。此外,使用两种致死浓度(LC25 和 LC50)的精油处理 Culiseta longiareolata 的四龄幼虫,然后对个体存活进行生物统计学和生化研究。研究发现,该化合物在减少体体积的过程中干扰生长,不同时期的主要生化成分(蛋白质、碳水化合物和脂质)受到影响。两种浓度(CL25 和 LC50)都会通过 GST 活性的增加和 GSH 速率的降低来激活解毒系统。因此,建议将植物精油(芸香)作为控制蚊子幼虫的植物药。使用两种致死浓度(LC25 和 LC50)的精油处理 Culiseta longiareolata 的四龄幼虫,然后对个体存活进行生物统计学和生化研究。研究发现,该化合物在减少体体积的过程中干扰生长,影响不同时期的主要生化成分(蛋白质、碳水化合物和脂质)。两种浓度(CL25 和 LC50)都会通过 GST 活性的增加和 GSH 速率的降低来激活解毒系统。因此,建议将植物精油(芸香)作为控制蚊子幼虫的植物药。使用两种致死浓度(LC25 和 LC50)的精油处理 Culiseta longiareolata 的四龄幼虫,然后对个体存活进行生物统计学和生化研究。研究发现,该化合物在减少体体积的过程中干扰生长,不同时期的主要生化成分(蛋白质、碳水化合物和脂质)受到影响。两种浓度(CL25 和 LC50)都会通过 GST 活性的增加和 GSH 速率的降低来激活解毒系统。因此,建议将植物精油(芸香)作为控制蚊子幼虫的植物药。
