Chemical composition and toxicity of Moroccan and essential oils against , the potato moth.

The current methods employed to mitigate losses caused by primarily rely on the application of synthetic insecticides. We have utilised essential oils of L. and against . The essential oils were obtained using hydrodistillation and analysed gas chromatography-mass spectrometry. essential oil contained D-limonene (25.12%) and D-carvone (7.47%) while the essential oil of was rich of 3,3,5-trimethylcyclohexene (27.93%) and camphor (22.50%). Five concentrations (0, 1, 2, 4, and 8 µL/L of air) were applied to the four phases of , neonate larvae, nymphs, eggs and adults. The results of the biological tests showed that spearmint oil was more toxic than wormwood oil, particularly at the adult and Chrysalide stages. Essential oils could be considered good alternatives to chemical pesticides for the protection of potato crops.
