Abstract

The essential oils extracted by hydrodistillation from fivearomatic plants from Algerian West –Ammoїdes verticillata (Apiacae), Origanum glandulosum (Lamiacae), Thymus capitatus (Lamiacae), Rosmarinus officinalis (Lamiacae), Artemisia herba-alba (Asteracae), were tested with various amounts on the larvaeof Tineola bisselliella, under the conditions of laboratory (Temperature of 26°C and with a relative humidity of 75 %). These oilscaused a significant larvicidalactivity. The essential oils extracted from Artemisia herba-alba, Rosmarinus officinalis, Origanum glandulosum are most toxic with LD50of 5,92μL/50,24cm², 6,66μL/50,24cm², and 7,16μL/50,24cm² respectively, Ammoїdes verticillata present alittle variable toxicity with LD50= 7,95μL/50,24cm², whereas the essential oil of Thymus capitatus is the least toxic on the larves of T. bisselliella with one LD50de 9,81μL/50,24cm².The analysis of the chemical composition shows the richness of five essential oils in compounds known for their insecticidal properties like α-pinène, β-pinène, p-cymène, carvacrol, camphre, γ-terpinène, and1,8-cineole, what explains the results obtained.

从阿尔及利亚五种芳香植物中提取的精油的杀幼虫效果评价：对双锥虫的测试（鳞翅目：Tineidae）

从阿尔及利亚西部的五种芳香植物——阿胶（Apiacae）、牛至（Lamiacae，在实验室条件下（温度26°C，相对湿度75%）。这些油具有显著的杀幼虫活性。从白蒿、迷迭香、牛至中提取的精油毒性最大，LD50分别为5,92μL/50,24cm²、6,66μL/50:24cm²和7,16μL/50~24cm²，而头状百里香的精油对双孢T.bisselliella幼虫的毒性最小，其LD50de为9,81μL/50,24cm²。化学成分分析表明，五种精油富含以其杀虫特性而闻名的化合物，如α-pinène、β-pinèe、p-cymène，香芹醇、camphre、γ-萜品油和1,8-烯醇，这解释了所获得的结果。
