Abstract

Ziziphora hispanica L. and Mentha pulegium L. are aromatic shrubs known to produce essential oils demanded by food industries. This study reports on the insecticidal activity of these two oils harvested in Khenifra (Morocco) and of its major compound (Pulegone) against the main legume bruchids. Chromatographic analysis revealed the presence of 33 compounds in the essential oil of Ziziphora hispanica (EOZH) and 24 compounds in the essential oil of Mentha pulegium (EOMP), with pulegone being the most dominant in both with percentages respectively of 79.1% and 63.8%. According to the insecticidal activities exerted, the two essential oils, as well as the pulegone, showed significant results against all the bruchids tested of legumes. Pulegone has shown good insecticidal activity, thus the lethal doses of 50% are between 61.6mg/g and 74.4mg/g, which explains the remarkable activity of the two essential oils which are rich in this molecule. moreover, the addition of essential oils in the storage of legumes does not have a significant effect on the legumes and does not diminish their nutritional qualities. This study indicates that essential oils and their main constituent have the potential to be developed into botanical insecticides.

富含蒲公英酮的精油对豆科植物的杀虫作用:以西班牙紫叶花和蒲公英花为例。

西班牙紫枝和薄荷是一种芳香灌木，以生产食品工业所需的精油而闻名。本研究报道了在摩洛哥Khenifra收获的这两种油及其主要化合物Pulegone对主要豆科植物的杀虫活性。经色谱分析，西班牙紫枝挥发油(EOZH)和薄荷挥发油(EOMP)中分别含有33种和24种化合物，其中以紫枝酮含量最高，含量分别为79.1%和63.8%。从杀虫活性来看，这两种精油以及普乐酮对豆科植物的所有糙毛虫均有显著的杀虫效果。普乐酮显示出良好的杀虫活性，50%的致死剂量在61.6mg/g ~ 74.4mg/g之间，这就解释了富含普乐酮分子的两种精油的显著活性。此外，豆科植物在贮藏过程中添加精油对豆科植物的营养品质没有显著影响，也没有降低豆科植物的营养品质。本研究表明，精油及其主要成分具有开发成植物性杀虫剂的潜力。
